Bowling Ball Rg Numbers

The bowling ball rg is one key measurement engineers use to identify how the mass distribution inside a bowling ball is concentrated.

Bowling ball rg numbers. Just as the track flare potential and differential of rg ratings are important pieces of information the rg numbers ratings is also a key factor in bowling ball construction. Using a different finish can affect the way the bowling ball interacts with the lane so be careful if you decide to have the bowling ball refinished while at the pro shop. Mass distribution numbers describe the distribution of mass in the bowling ball. Understanding the rg numbers when shopping for a new bowling ball will help you in the selection process.

The radius of gyration is an account of the location of the mass inside a given bowling ball and relates whether the ball mass is concentrated toward the center of the ball low rg toward the coverstock of the ball high rg or between the two points medium rg. Depending on the drilling layout that is applied the numbers may go up or down from there. High rg numbers indicate that the balls mass is distributed more towards the cover cover heavy which promotes length through the heads of the bowling lane. Now these numbers will change once your pro shop drills into the bowling ball.
