Bowling Ball Rg

Rg numbers range from 2 460 to 2 800 but some companies have converted them to a 1 10 scale to help give the consumer a better frame of reference.

Bowling ball rg. If you set out to determine how to select the best bowling ball rg then there are three factors to help you to make the right choice. The rg of a bowling ball tells you how soon the core is designed to roll. Usbc could change the rule. Rg scales every ball will rate somewhere between 2 460 and 2 800 although many ball manufacturers have converted to a 1 10 scale to give consumers an easier frame.

The lowest allowed by the usbc is 2 43 the highest is rg 2 80. Rg means radius of gyration. 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. A quick explanation of what an rg radius of gyration rating is in reference to a bowling ball.

Mass distribution numbers describe the distribution of mass in the bowling ball. Well rg means radius of gyration. 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. The bowling ball rg is one key measurement engineers use to identify how the mass distribution inside a bowling ball is concentrated.

If you were to create a spherical core that was 2 46 inches wide and 2 8 inches tall it would look like a perfect sphere on first glance although upon close inspection you would be able to tell that it was actually a slightly squished ball. 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. Think of it like a. 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.
