What do the specs on a bowling ball mean?

With that being said, the lower the RG number the earlier the hook. Just the opposite with High RG, the higher the number the more length you will get out of the bowling ball. Stated earlier, Differential is the number that tells us Track Flare Potential.

What does RG and differential mean in bowling balls?

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 low Rg for a bowling ball?

Radius of Gyration (RG) – An account of the location of the mass inside a bowling ball. Rg tells us whether the ball has the mass toward the center of the ball (low rg), toward the cover of the ball (high rg) or somewhere in between (medium rg). Low rg balls rev up quickly.

What does RG mean on a bowling ball?

High RG. The USBC defines RG ( radius of gyration ) as: Measured in inches, radius of gyration is the distance from the axis of rotation at which the total mass of a body might be concentrated without changing its moment of inertia. Simply put, RG is when your ball begins to rev up.

What is bowling ball flare potential?

The bowling ball flare potential is the maximum amount a bowling ball can migrate while traveling down the lane. Flare potential can be used as an indicator for which bowling balls are best suited for certain patterns and conditions i.e. oily lane conditions (high flare) and or drier lane conditions (low flare).

What is a urethane bowling ball?

High RG means the exact opposite: the higher the number, the more length the ball will create. When we see the RG number advertised on a ball box, they provide the low RG plane number.

What is RG value?

The Rg represents the root mean square distance of the molecule’s components from the mass center of the molecule. The single Rh and Rg numbers generated by a GPC/SEC analysis are the weight average values obtained from compiling the calculated values at each data slice.

How do I choose a bowling ball core?

Some say your ball should be approximately 10 percent of your body weight, up to the maximum 16 pounds. Most pro bowlers use 16-pound balls, although more than you think use 15-pounders. Another method is to add one or two pounds to the weight of the house ball you normally use.

How do bowling ball sizes work?

A bowling ball should weigh 10 percent of your body weight (up to 16 pounds), which means you really shouldn’t be grabbing, say, an 8-pound ball if you weigh 150 pounds. You want some weight to the ball, but it shouldn’t be so heavy that it’s uncomfortable. Young bowlers should choose balls in the 6 to 14 pound range.

What do the numbers mean on a Brunswick bowling ball?
