bowlingball.com Differential of RG Specifications
When searching for information about any given bowling ball at our site, you can easily find
bowlingball.com Differential of RG Specifications which will help you make a good decision in purchasing your next bowling ball. The
bowlingball.com Differential of RG Specifications is one key factor relating to bowling ball construction and the hook potential a given bowling ball possesses.
The United States Bowling Congress defines the RG (Radius of Gyration) of a
bowling ball as a measurement in inches and 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. 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.
bowlingball.com describes the Differential of RG as a measurement varying numerically from .01 - .08 in range. These measurements describe the
bowling ball flare potential rating and indicate if the flare potential is low, medium, or high.
The higher the number, the greater the track flare potential.
Placing Differential of RG range measurements into three relative numerical spreads would read as follows:
Low Diff.-RG: .01 - .02 (low flare potential)
Med. Diff.-RG: .021 - .04 (med flare Potential)
High Diff.-RG: .041 - .08 (high flare potential)
The United States Bowling Congress defines Intermediate Differential of RG as the difference in radius of gyration between the Y (high RG) and Z (intermediate RG) axes on a bowling ball.
Some manufacturers use an Intermediate Differential rating (sometimes referred to as Mass Bias rating) to accompany the Differential and RG ratings when providing technical data on their given bowling ball products. bowlingball.com also provides this information on Intermediate Differential, as necessary, when our visitors reference the technical specifications on any given bowling ball.
Intermediate Differential of RG measurements range in inches from 0.008" - .037."
Low Int. Diff. .008 - .020
High Int. Diff. .021 - .037
The higher the measurement of Intermediate Differential, the greater the asymmetry and the lower the Intermediate Differential, the lower the asymmetry of a given bowling ball. The greater the asymmetry, the more area is created at the break point and the ball will respond to friction faster symmetrical balls.
As an example of our
bowlingball.com Differential of RG Specifications reference, let's look at the posted specifications for the
Chosen Path Pearl Black/Lime Green 2024 DEAL which is available for purchase at our site:
Release Date: 10/24/2013
Perfect Scale®: 228.4
Performance: Pro Performance(10)
RG: 2.52
Differential: 0.043 v
Mass Bias Diff: 0.015Flare Potential: 6"+ (High)
Durometer: 76
Lane Condition: Medium-Heavy
Finish: Polished
Coverstock: Reactive Resin
Coverstock Name: GPS Navigational Pearl
Factory Finish: 2000 grit Abralon/Factory Polish
Color: Black / Lime Green
Core Type: Asymmetric
Core Name: SG 19.5 Asymmetric
Quality: First Quality
Please note all of the technical data details referenced for the
Chosen Path Pearl Black/Lime Green 2024 DEAL ball and make special note of the references to the highlighted Differential and Mass Bias Specifications. The Differential is .043 which falls into the high Differential rating as noted above in our chart. Mass Bias, in this case, is a reference by the manufacturer to the Intermediate Differential rating and shows as .015 which is a medium rating also indicating the Chosen Path Pearl ball has a high degree of asymmetry in the core design.
According to our informal chart above, this ball would fall into a low RG rating with high track flare potential and has an asymmetric core type matching well with medium-heavy and heavy oil conditions.
Next time you are searching for a new ball at our site, please check out the description details and the Differential specifications to help you select a new ball with the appropriate hook potential rating.
It should be mentioned that the coverstock surface texture influences the hook potential of any given bowling ball and can be altered or modified to help you further control the hook potential.
