2-piece ball: Consists of the outer shell and the weight block. The weight block can be modified, thereby changing the dynamics.

3-piece ball:Consists of the outer shell, the filling material (Compund) and the weight block.

Axis of Rotation:Horizontal position of the axis after the ball is released in °.

Axistilt:Vertical axis position after the ball is released in °.

Backend: stop motion, strength, change of direction after the breakpoint.

Balance Hole: balancing hole through the proper placement of such a hole, you can change the ball dynamics and the running behavior. Through a certain position on the running performance can be increased or decreased. In the predominant case, we positioned the balance hole on the vertical axis line.

Bowling ball: A bowling ball has a maximum circumference of 27 "(68.58 cm) and a maximum diameter of 21.6 cm In addition, the weight of a ball is limited to 16 lbs...

Center of Gravity (CG) were: focus, often characterized by a logo. Indicates the position of the center of weight of the entire ball. For over drilling the second important feature next to the pin.

Torque Core: Core torque meant here is the distribution of mass within the core, the core and the asymmetry of the arrangement of the lever arms. Furthermore, one can see the kind of change of direction by Cor torque.

High Core Torque: effective, but very strong change of direction

Low Core Torque: uniform and predictable response

Cover Stock: outer shell of the ball, which can consist of different materials, such as polyesters, urethanes, Reactive

D-Scale: hardness of the outer shell, measured in Durometer

Differential: strength of direction change.

The differential is the difference between the position of the core toward the shell.
If the core of the ball more to one side, the Differnetial is higher.
He is the central core in the core interior, the position is balanced. The ball has little differential.
The higher the differential, the more aggressive is the change of direction at the breakpoint.
The lower the differential, the more uniform and stable the running behavior of the breakpoint.
By Drilllayouts little different length adjustment can be made at low differential balls.
When balls having a high differential in contrast, up to three times the length can be achieved.
For data to the balls the differential is usually as RG Diff. specified.

Dull: matt ball surface, suitable for cars with more oil or long oil pattern units

Finish Out of Box: State of the ball surface after leaving the factory.

Horizontal Axial line (HAL): the line that runs horizontally right through the center handle and the PAP.

Hookout: 0 ° axis, the ball can no longer produce any change in direction

Lbs. Unit weight of a bowling ball. Lbs. = Pound, a pound is about 453 grams

Length: specifies how long the ball is run until it changes direction.

Negative Axis Point (NAP): negative axis point is located opposite the positive axis point.

Particle: additives in the shell, may be made of different material such as ceramic or glass.

In addition, a distinction is made between low (low), medium (medium) and high (High Load) charge of particle fractions in the shell.
Wherein high load particle balls is more than 5% of the total amount.
In addition, the particles are injected at different depths in the shell (shot).
Particle balls should have the advantage in producing various tracks smoother ball run.

Particles are called by different manufacturers: ProActive, mica, Pet
Pin: The pin is a round contrasting point on the ball he is the center of the weight block (core) to. There are different pin positions, in relation to the CG (CG Pindistanz pin):

- Pin Add: 0 "to 1 1/2"
- Pin Medium: 1 1/2 "to 3"
- Pin Out: More than 3 "

Positive Axis Point (PAP): position Tivier axis point, the axis around which the ball was when the ball is released first rotates. The position of the PAP may be influenced by different charges. Therefore, the position in almost all bowlers is different.

Radius of Gyratin (RG): The mass distribution in the ball is meant. High RG balls (high RG) concentrate their mass under the skin and produce a longer straight. Balls with a low RG (low RG) have concentrated their more mass in the center of the ball, thereby producing an early rolling phase.

Shiny: Polished ball surface, suitable for cars with a little oil units or short oil pattern.

Track flare: Hike of the race of the tax until impact. A large flare always brings a fresh, dry piece of race track surface in contact with. When the ball comes from the oil in the dry part of the web, created by the dry piece of tread and a larger hook than previous balls with a lower track flare. By the width of the flare you see which balls you should pack up again or should play.

Track flare Potential: maximum size of the race.
Prerequisite: The player must release maximum energy in the delivery, but this create very few players.

There are three types of Trackflare that a bowler can produce:

High track flare: the race passes close to the finger and thumb holes long, thereby improving the response to oil is produced, less length and former Hooks

Flare medium track: the race is further away from the bore, characterized a slightly evenly ball-pattern is generated.

Low Track flare: the race is far away from the hole, it is not used much ball surface, it is more un length produces a small hook later.

Vertical Axial line (VAL): vertical axis line, the vertical line that passes directly through the PAP.
