What does RG and diff mean on a bowling ball?

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 mean on bowling ball?

Low RG vs.

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. Low RG bowling balls rev up earlier on the lane than high RG bowling balls.

What does a low diff mean in a bowling ball?

LOW DIFF:.

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.

What is int diff bowling?

Intermediate differential - The difference in radius of gyration between the Y (high RG) and Z (intermediate RG) axes on the bowling ball. The higher the the intermediate differential the stronger a balls PSA.

What is RG and diff?

We define differential as the difference between the maximum and minimum radius of gyration, better known as the X and Y-axes of the weight block. RG-differential indicates the bowling ball's track flare potential. Therefore, the higher the differential, the more the ball will flare.

What are the numbers on bowling balls?

Bowling balls have a RG (Radius of Gyration) converted to a scale of 1-10. 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. Mass distribution numbers describe the distribution of mass in the bowling 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.

How do you read a bowling ball stats?

Just the opposite with High RG, the higher the number the more length you will get out of the bowling ball.
...
Now lets break this down with the numbers involved:

1. RG ranges from 2.460” – 2.800”
2. Low RG: 2.460” - 2.570”
3. Med. RG: 2.570” - 2.680”
4. High RG: 2.680” - 2.800”

What is the RG value of a bowling ball?

The RG value of a bowling ball is defined by the USBC as the measurement of the distance of where the ball's total mass is concentrated from its axis of rotation without any changes to its moment of inertia.

Can you use Windex on a bowling ball?

According to most bowlers who have used Windex as a bowling ball cleaner, it does wonders getting dirt and grime off the 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 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.

What is flare in bowling?

Flare: To expand or open outward in shape.

At that point it simply rolls end over end. The easiest way to visualize this is when you throw the ball. The rings of oil draw the flare for you. Every time the balls has one complete roll it will shift to another axis, creating a new oil ring.

Are bowling balls perfectly round?

Balls used in pin bowling must be exactly round in shape, but they contain hidden weights that affect their balance and rotation. They also differ from lawn-bowling balls by having finger holes; they may have two (for the thumb and middle finger) or, more popularly, three (for the thumb and middle and ring fingers).

What is the correct bowling form?

Hold your hand straight while you swing the ball out and back. Begin to rotate the wrist, hand, and fingers on your bowling arm toward the opposite side of your body as the ball comes forward. If you're left-handed, rotate your wrist toward the right. If you're right-handed, rotate your wrist toward the left.

What is a good bowling ball for an intermediate?

Brunswick Tzone – Best Overall

How do I know what bowling ball to buy?

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.

What bowling shot does not curve?

The straight shot is exactly what its name implies except that it is rolled down the alley slightly off center in order to hit the first pin at an advantageous angle. The hook shot consistently beats other shots in producing strikes.

What is durometer in bowling?

A durometer is a device which is used to indent an object (like a bowling ball) to measure the resistance to indentation. This resistance reflects the hardness of an object. Since objects can be very soft or hard, there are multiple Durometer scales used to determine hardness. In bowling we use the Shore D Scale.

What does polishing bowling ball do?

Polishing is used to reduce the friction on the surface of a ball. There are many types of polishes available on the market. From polishes that clean off grime and belt marks, to polishes that are available in different grit levels for medium oil conditions to dry conditions.

How do you get more revs in bowling?

In bowling, we can add power (more revs) by adding lag in the forward swing. Adding lag in the forward swing requires a couple of arm and hand action moves so you get into position to uncoil your wrist as your thumb exits the bowling ball producing an increase in your rev-rate.

How do you drill a bowling ball?

Choose a hole configuration.

1. A conventional grip is achieved by drilling holes deep enough so that your fingers and thumb are inserted into the ball up to the second knuckle joint. ...
2. A fingertip grip is achieved by drilling holes that allow your fingers to be inserted into the ball up to the first knuckle joint.

What does a yellow dot on a bowling ball mean?

The pin marks the top of the core inside the bowling ball. It is also the point around which the ball wants to rotate. Given an infinite length and time, a ball will eventually rotate around the pin, either with the pin down on the lane or on top of the ball.

Why do bowlers have two balls?

There's a particular reason that bowlers carry more than one ball. Most bowlers roll their first shot with a hook, and a spare ball is used for a more precise second throw that won't hook away from the pin(s) that remain.
