Bowling Ball Rg And Differential

Scott pohl owner of on track pro shop breaks down differential rg cores and what it all means to you and your game.

Bowling ball rg and differential. Within the core of any bowling ball exists measurements of mass distribution which are used to measure a bowling ball in motion on the lane surface. In a bowling ball the usbc has required all balls have a low rg no shorter than 2 46 inches and the high rg can be no longer than 2 8 inches. Now companies also provide us with differential along with the rg. The bowling ball differential rg is one key measurement engineers use to identify the difference of the rg of a given bowling ball s x axis weight block vertical measurement compared to the rg of the y or z axes weight block.

Bowling balls are made with different coverstocks and cores. Rg and differential terms used in bowling ball specifications rg differential and rg what does this mean. I first must tell you i am not a scientist or a ball designer.

Bowling ball differential ratings. Stated earlier differential is the number that tells us track flare potential. High rg the usbc defines rg radius of gyration as. The bowling ball differential of rg is one key measurement engineers use to identify the difference of the rg of a given bowling ball s x axis weight block vertical measurement compared to the rg of the y or z axes weight block horizontal measurements.

If you would like to identify the bowling ball hook potential when searching for your next bowling ball then check out the differential of rg rating provided by the manufacturer to aide in your equipment selection process.
