We define differential as the difference between the maximum and minimum radius of gyration, better known as the X and Y-axes of the weight block. RG-differential indicates the bowling ball's track flare potential. Therefore, the higher the differential, the more the ball will flare.
What does differential do to a bowling ball?
Differential is an indicator of a bowling ball's track flare potential. Bowling balls with lower differentials are more stable, therefore generating less track flare potential. Bowling balls with higher differentials are unstable, therefore generating a much larger track flare potential.
What does RG and diff mean on a bowling ball?
In short, the RG of a bowling ball is an account of the location of that mass inside the given bowling ball. Differential of RG is the difference between the maximum and minimum Radius of Gyration. RG-differential indicates the bowling ball's track flare potential.
What is considered a low RG bowling ball?
Low RG: 2.460” - 2.570” Med. RG: 2.570” - 2.680” High RG: 2.680” - 2.800”
What does PSA mean in bowling?
The preferred spin axis (PSA) on an asymmetrical ball is one of the most misunderstood topics surrounding bowling ball technology in today's game. A majority of bowlers don't realize how important it is and how much more the ball reaction can be fine-tuned when drilling an asymmetrical ball.
27 related questions foundDo all bowling balls have cores?
Most modern “two-piece” bowling balls have, at minimum, a coverstock, a core, and a spherical outer core.
What is RG and diff?
We define differential as the difference between the maximum and minimum radius of gyration, better known as the X and Y-axes of the weight block. RG-differential indicates the bowling ball's track flare potential. Therefore, the higher the differential, the more the ball will flare.
What do the numbers on bowling balls mean?
As mentioned, these small numbers usually mean the serial numbers of the balls. These serial numbers are typically preceded by the code USBC. These numbers can help you identify crucial information about the ball. These include things like its manufacturing date, its type, and more.
What does low RNG mean in bowling?
Low RG numbers indicate that the balls mass is distributed more towards the center (center heavy) which promotes an earlier roll through the front part of the lane. Medium RG describes sufficient bowling ball skid length to reach the mid-lane before transitioning into the hook phase of overall motion.
What is hook rating for bowling balls?
The Perfect Scale® ranges from 1 to 300. Plastic bowling balls with very low hook potential, rate a 5. The highest number achieved on the scale to date is 237.7. As you can see, we've left room for improvement on our scale in anticipation of new technologies that will add additional hook potential.
What bowling shot does not curve?
The straight shot is exactly what its name implies except that it is rolled down the alley slightly off center in order to hit the first pin at an advantageous angle. The hook shot consistently beats other shots in producing strikes.
What is intermediate differential?
Intermediate differential - The difference in radius of gyration between the Y (high RG) and Z (intermediate RG) axes on the bowling ball. The higher the the intermediate differential the stronger a balls PSA.
What is ball flare?
Flare: To expand or open outward in shape.
When a ball flares, that means that as it rolls, it continues to migrate to a different axis with each roll. It does this until it reaches it's preferred spin axis. At that point it simply rolls end over end. The easiest way to visualize this is when you throw the ball.
Why do bowlers have two balls?
There's a particular reason that bowlers carry more than one ball. Most bowlers roll their first shot with a hook, and a spare ball is used for a more precise second throw that won't hook away from the pin(s) that remain.
What is a pancake core bowling ball?
PANCAKE CORE
This is the traditional core design found in the typical spare ball, but with carbon fiber added. It features a high RG and low differential to keep flare and hook potential low.
What Coverstock hooks the most?
In order from Strongest to Weakest Coverstocks are: Solid, HyBrid, Pearl, Urethane, and then Plastic. This is not always true but more often than not, this is the order they go.
What is pin buffer in bowling?
The distance of the pin to the bowler's initial PAP controls the amount of total flare. The PSA to PAP distance dictates how quickly the ball loses axis rotation (side roll). The pin to VAL distance, also known as the pin buffer, controls the shape of the hooking motion at the breakpoint.
How important is the PAP on the bowling ball?
The PAP is important because it can be seen throughout a shot and the bowling ball's reaction is influenced by how far the pin and mass bias is away from the PAP.
Does pin to CG distance matter?
It doesn't really matter. I requested a 3-4" pin from Motiv and for some reason the ball i got only had a 2 1/4 - 2 1/2" pin. I still used the same layout i planned on using.
What is a high RG?
Simply put, RG is when your ball begins to rev up. Low RG bowling balls rev up earlier on the lane than high RG bowling balls. Low RG bowling ball cores have more mass on the bottom of the core. High RG bowling balls rev up later on the lane. These cores have the majority of their mass located on the top of its core.
What does an F mean in bowling?
An “F” indicates a “foul,” in which part of your body went past the foul line. An “O” around a number indicates the pins that were left standing after the first roll were in a “split” formation, though you can also use an “S” before the number to indicate a split formation.

What bowling ball hits hardest?
The Ebonite Choice is the most aggressive bowling ball out there thanks to its durable GSV-1 cover stock which eats up heavy oil patterns and turns it into fiery back-end reactions. It's such an aggressive bowling ball that the lack of a heavy oil pattern could actually be detrimental to its cover stock.
