Types Of Bowling Ball Cores

Symmetrical bowling ball cores are equal proportion from top to bottom prior to being drilled.

Types of bowling ball cores. The big difference between these coverstock materials is how they perform and react on the lane surface. Symmetrical cores have a radius of gyration values of the y high rg while the z intermediate rg hinge does not vary by more than 5 percent of the overall differential of the bowling ball. Plastic or polyester also known as your spare ball. This makes one end of the ball heavier than the other which can give them low track flare and hook potential.

Symmetrical and asymmetrical cores there are two types of bowling ball cores. Pancake type pancake type cores are literally bowling ball. That is it may be symmetrical horizontally but not vertically. Asymmetrical symmetrical urethane and plastic.

For this discussion we ll broadly classify cores into three different types. Pancake type or high mass designed to prevent the ball from getting into a heavy roll pancake or high mass bowling balls have a thin layer of pancake or puddle shaped weight block finished with a large amount of filler material. They are outlined in more detail below. There are three main types of bowling ball cores that we ll discuss.

A symmetrical core is the same all the way around one axis although it is not necessarily the same around another. There are 3 main types of cores in a bowling ball which include 3 piece 2 piece symmetrical and asymmetrical. Now here are the bowling ball types we get to choose from. Pancake type symmetrical and asymmetrical.

Bowling balls are made of four main different types of coverstocks plastic urethane reactive resin and particle proactive. In increasing level of complexity the three main types that we ll explore are the low performance pancake type core the symmetrical core and the asymmetrical core. The rg values in the y and z axes of asymmetrical cores vary by more than 5 percent. As an example when bowling ball core designs include a shape which places mass in specific areas near the center of the ball and also places mass to the top of the ball the overall ball motion will become one which promotes early roll to fight front end excessive oil coupled with a strong back end reaction from the break point to the pocket.

Asymmetrical bowling cores have three x y and z this. Modern bowling ball cores come in a wide variety of types shapes and sizes. Modern day bowling ball cores come in a wide variety of types shapes and sizes. Who would this type of ball match up to.
