The differential is defined as the difference between the maximum and minimum RG. So the DIFFERENTIAL tells us the bowling balls flare potential (or overall hook). This measurement determines the flare potential as a rating of high, medium, low.
How does differential affect 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 high differential bowling ball mean?
RG-differential indicates the bowling ball's track flare potential. Therefore, the higher the differential, the more the ball will flare. The more flare on a bowling ball, the more the bowling ball cover touches the lane surface. With more of the surface touching the lane, the earlier the ball wants to hook.
What's the difference between RG and differential bowling?
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 does RG do to a bowling ball?
Low RG vs.
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.

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.
What bowling ball should I use?
Find your ideal ball weight.
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.
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.
What does backend mean in bowling?
Backend is the ability to convert the ball's revolutions in to a forward move in the final 3rd of the lane, after the ball reached its breakpoint and revolution axis and the ball's path point into the same direction: the pocket.
Are bowling balls heavy?
There are many different types of bowling balls, and they typically weigh between 6 and 16 pounds. The lighter bowling balls are typically used for kids who want to bowl, while the heavier bowls are meant for adults.

Are heavier bowling balls better?

Where should the pin be on a bowling ball?

Do 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 pin buffer?
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.
What do the numbers mean on a Brunswick bowling ball?
Re: What do the Numbers on a Ball mean
Yes they are the serial number of the ball. Each ball for a manufacture has a unique number assigned as it is made. For Brunswick it is a code. If you know the code you can tell when the ball was made and what batch it was in.
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.
