Interior of the Bowling Ball
Home Bibliography
One of the most essential aspects of bowling is the ball that is being used.
The interior of the bowling ball is the basis its motion. Most bowling balls
made from a mixture of urethane, plastic, and reactive resin with a maximum
weight of 16 pounds. The outside of the ball is a hard shell with a smooth
surface to reduce friction as the ball goes down the lane. While the outside of
the ball is what makes contact with the lane and the pins, the inside of the
bowling ball is the more important part.
Inside the ball is a weight block that off sets the weight distribution to effect
the spin of the ball and its curve as it rolls.

A pin can be seen from the surface of the ball and shows which side is more
heavily weighted. The weight is also closest to the ouside of the ball on this
side. How the weight effects the curve of the ball is very important to a bowler's
performance because it effects the angle at which you can hit the pins.
See The Angle link for a more detailed discussion on how the angle effects
a bowlers game.
