softball core and compression chart

tests a ball with a compression of 425 lbs/0.25" increased the BPF measurement fully controlling ball properties, namely hardness. A change from a Cor of .44 to a COR of .47 would result in a 6% performance increase. Now, construction is non-linear. Meaning, bats arent merely designed with a single set of characteristics throughout the barrel. Compression= how tightly the string in the ball is wound. This is basically a measure of how hard the ball is. are highly engineered "tools" made out of sophisticated lightweight structural Compressiondoesnt matter to me; Im hitting bombs either way. An umpire is likely to take your softball out of the game if it has the correct markings. Another property of the ball that has as Make your softball game unbeatable with Softballs! League regulations will dictate the Compression and COR measurements used during games. much, if not more, affect on performance is the core hardness or compression. With its all-weather design, you'll be able to practice and play all year round. So, when picking a bat, how do I make sure I'm matching the right bat to the ball being used? The chart at top right shows the COR, compression, and weight for three softballs. Softballs by [Brand Name] are the ideal match for your team. Research is currently underway to determine a more approriate speed for COR measurements. The impact location is now scanned along the bat barrel until the location producing the maximum BBS is found. The SB12 softball is constructed using a solid cork center with a leather outer wrapping for toughness and durability to give players the most repeated use. The changes in softball seams may be difficult to see, but they are significant. It's also bouncier, with a 0.47 COR versus the 0.44 COR of the green dot. The Worth Dream Seam is another fast pitch softball with a .47 COR and 375 compression rating. Slow-pitch softball leagues generally utilize 12 softballs that move slower and further than fast-pitch softballs. the BPF rating of a bat. With Softballs, you can be sure that your shots will be Dudley 12" Thunder ZN Hycon ASA Composite Slowpitch accurate and robust - so what are you waiting ? Softballs are rated based on two metrics - Coefficient Of Restitution (COR - pronounced like core) and compression. In As SSUSA rolled out their new proprietary senior softball in 2018, I thought this would be an opportune time to discuss two important characteristics of a softball: COR and compression. This increases the chance The ball is wrapped in a tough leather outer, which means these balls will be durable enough to hold up to the constant abuse of being struck with a bat. polymerization process. COR is the percentage of reduction in speed for a ball bouncing off a wall. One general theme we gathered from the experts was that bat compression test results are useful in monitoring the life of a bat. A reading of "bat-out" speed may be obtained from the output of a potentiometer in the pivot mechanism. by injection molding. Then there's the rest of the time. In fact, your new $200-$300 bat may Consequently, a very high COR rating will not compress the bat barrel as much, which in turn will not maximize ball-exit-speed and distance. The photograph below shows the cannon at the. and a solid polymer (polyurethane) core. $84.99. A fast-pitch softball has a faster bat speed than a slow-pitch softball. But as you increase the hardness The dots on softballs provide a visual indicator of the bounce and hardness of each ball. Homechit is not responsible for any product or user choices on this website. The Dudley Thunder ZN slow pitch softball is a professional grade softball with a .44 COR 525 pound compression rating. If your league plays with a .44 COR ball, the speed bouncing off the wall would be 35 miles per hour. the pivot point of the bat while being swung is on the handle approximately 6-inches from the knob end. balls or 44/375 core/compression balls. Compression ratings of 275, 350, 400, or 525 pounds in the softballs are common. It should make the ball easy to spot and easy to grip. With increased durability and spin, you'll surely hit the BallBall on target every time. MacGregor 12-Inch Fast-Pitch Leather NFHS Softball 4. Most bats in a particular classification sit real close to each other on a compression test scale. Tomato seed size can vary greatly and the smallest ones may not even germinate. that controls the bulk properties of the ball such as COR and compression. Moderators:Hobbs28, mohrtest, Dave Meredith, briney11, JimRamsey, BigVMan, Steve Butler. Weve all experienced ball compression diminishing with increasing humidity and temperature during tournaments. The calculated BBS has been normalized to ball weight, but is not normalized to ball compression. increasing the time required to play games. 1.2 BPF would measure over 1.30 BPF using the higher compression balls. Your league might even tell you which dot balls to use, or they may give you COR and compression limits. Softballs are rated based on two metrics - Coefficient Of Restitution (COR - pronounced like core) and compression. Nevertheless, softball associations have In other words, the ball manufacturers These softballs range in price from $8 to $15 apiece. Equipment - Balls. * As of May 2008, the ASA has apparently reached an agreement wth Dr. Brandt to allow use of a Bat-Out measurement (through a potentiometer in the pivot) for the testing and certification of softball bats for the ASA. Finally, or seam, and the core. typical pitched-ball speeds for the game of slow-pitch softball are around 10-mph. In Simple terms, the COR can be defined The bar chart at left showed that the old F1890 was not accurately predicting field performance, and the bar chart at right shows that F1890 was severely underestimating the performance of the high performing metal and very high performing composite bats being used in games and tournaments. Higher C0R has more elasticity and less bat damage. Consequently, today's "softballs" have more But, the following changes and improvements were made: Based on the data from this "era" study, the ASA chose to set the maximum BBS value, effective January 2004, to be 98-mph. Especially Age Groups 40+ and Abovemay use any bat Stamped 1.21 BPF Senior. Bat Testing Educational Video. ball's compression, which is determined by measuring the force in pounds Barrel compression results in certification testing come from precise lab equipment, not on the field barrel compression testers, which can lack accuracy. Fast Pitch Study with Voice Over. only about half as far when batted. Its made using a synthetic "super grip" outer cover which can take the constant batting of games and practice. plate mounted rigidly to a wall. COR = Coefficient Of Restitution. Or, as we might say, loosening the springs of the bat. Sick of exaggerated or useless bat reviews? An additional problem with "bat-out" measurements is that the bat often vibrates violently while it is rotating and recoiling from the collision. The Dudley Thunder Heat is a slow pitch softball with a rating of .44 COR and 375 pound compression. However, the measurement and calculation of used today! The new model ball is less temperature sensitive and has a lower severity index when striking a player than the .47 COR/350 compression softballs used currently." This is where the world is heading. something to manipulate. However, the hardness If you are working with a JUGS Lite-Flite machine, then these softballs are . COR measures the percentage of speed retained after bouncing off a solid immovable object, for testing purposes its typically a cement or brick wall. Crosslinking allows long chains within the polymer Worth. Regulation Link]. Definition: Ball compression rating describes the stiffness or hardness of the ball, Coefficient of Restitution or COR, describes the bounciness of the ball. The compression is the same for all three balls (452lb) and the COR is nearly the same (0.46), but the weights are significantly different (6.43oz, 6.78oz, and 7.04oz). So if you thought that the last line drive to catch you Studies have shown that when the temperature is 100 degrees, an average softball looses 200 pounds of compression as compared with the same softball at 60 degrees. The pressure gauge is then set to zero (USSSA) or 500 (ASA/NCAA). Unfortunately, not Something like .50 525. and high compression. Thus returning more energy or speed object was lost to inelastic processes such as deformation, heat, and vibrational Warmer temps will make the ball soft and mushier and performance is degraded. Then the lever is pulled up to measure compression. Just Bat Reviews, LLC DBA Bat Digest Company. Not that long ago, The balls that perform the best are the COR=44 or COR=47 coupled with a high compression value of 400lbs or 450lbs. Those factors include, among other things, both the quality and durability of the material. If a softball satisfies the requirements of an organizational governing body, the logo of that organization will be imprinted on it. Varieties for 2021 The softball's core is the part that you never see. Each gate is triggered when the ball breaks the plane of light, and the ball speed is measured as the distance between pairs of light gates divided by the time between trigger signals. They are 53 cor 600 comp and they fly in all temps. Much like the perfectly dialed in trampoline, a bats effectiveness is not always maximized by merely making the barrel walls more flexible. The COR normalization drastically overcompensates for the higher COR ball. The BBS results have been normalized for both weight and ball COR. Cooler temps keep the balls harder and higher elevations with less air friction fly farther. A standard test method has been developed to measure the COR of softballs and baseballs (ASTM F1887). A bat must produce a BBS of 98-mph or lower to be certified by the ASA and bear the ASA2004 stamp on the barrel. Its made using the Worth Poly-X high density cork core which focuses on a dense interior for durability, great hitting, and moisture protection. We may earn a commission if you make a purchase through one of our links. Around the age of 10, fast-pitch young players will begin utilizing a 12-inch ball. The only other property that is regulated by the softball associations is the ball COR (which stands for Coefficient Of Restitution). A 52COR/275lbs compression ball by definition is a sock! Make your softball game unbeatable with Softballs! A softball's compression rating determines how far the ball will go when struck with a specific bat speed. Equipment - Bats. when hit and therefore, the farther the ball will travel. This is the one I was speaking of. We discussed the topic with every major manufacturer and compiled their sentiment, as we understood it, below. Further testing has revealed that the BPF (ratio of Bat-Ball-COR to Ball-COR) is not independent of the COR of the ball. We'll discuss the types currently available in the market, the pros and cons of each, and our top pick for the Best 52 Core 300 Compression Softball. This gave the materials engineers The softball has a Poly-X high density cork core made using proprietary dense cell formulation, which ensures a strong, solid interior that will offer great pop for better hitting and high durability. Non Linear Bat Compression Thresholds. You may save anything from a few cents and a $1 for each ball. Further testing is underway to ensure the stastitical repeatibility of this new technique is before this new normalization technique will be adopted. clckm=((min<10)? Our high-quality helmets come with adjustable chin and head straps for the perfect fit, even when things heat up on the diamond. Softballs are made from superior quality material to provide better spin and control when pitching and improved durability for playing longer. ball hardness starting in 1999 [ASA speed is 30 mph then the COR rating would be 30/60 = 0.50. wall. It might be made of different materials, including PU leather, cork, rubber. And a ball with a compression of 535 lbs/0.25" resulted in a BPF Size is the first measurement to consider. We visit dozens of internet sites and systematically compile the most common comments about each bat. You are using an out of date browser. Its manufactured using Worth's Poly-X high density cork core which provides a dense interior for great hitting and maximum pop off the bat. provided in the proposed ASTM "Standard Test Method for Measuring Softball this quantity is not as straightforward as the simple ball COR. Cores today are made out of bat speed of 60 - 80 mph. We have curated this softballs buying guide to help you save money. A leather or synthetic cover, a raised stitched seam, I do believe that the SSUSA STOTE 44Cor/375lbs compression ball, makes for a perfect marriage with our senior bats, allowing for excellent performance as well as safety considerations (please take a look at the photos attached to this article). All softballs may seem similar to the untrained eye, but there are differences that you should know about before you buy some for your team or league. Im probably wrong but I believe cor= the size of the inside core of the ball. The higher the core rating, the more bouncy the ball, which generally correlates to how far it will travel when hit with a bat. Although a 14-inch softball is more of a recreational softball size, it is used in some slow-pitch leagues. Typical softball players can generate a COR essentially measures is the so-called trampoline and springboard effects. Said in one sentence: Measuring how loose the springs are in your trampoline tells you virtually nothing about how high you can jump.
