Bowling is an indoor sport, which is popular all over the world. People from all the age groups play this sport. It requires the player to lift a heavy bowling ball and roll it on the alley in an angle that the ball is able to knock off the bowling pins present at the end of the alley. However, all of this depends on the weight of the bowling ball. Here we will talk about different kinds of core materials of bowling balls that affect the weight.

The two categories of bowling ball cores

The bowling ball cores can be classified into the following categories –

  • Asymmetrical -in this, the weight of a core is not distributed evenly. This type is usually used by players, who are unable to put a nice amount of revolution in each shot.
  • Symmetrical – in this, the weight of acore is equally divided throughout. However, bowling ball cores can only be horizontally symmetrical.

It should be noted that neither of them is considered as more beneficial than the other. Each of them has their own functions.

The different kinds of cover stocks

A cover stock is a shell that is placed around the core of the ball. The various kinds of cover stocks are –

  • Plastic – the shells of these balls are made up of polyester mixed up with peroxide. These are usually scratch resistant and are very hard. They were introduced in the 1950s.
  • Urethane -the shells are created by the reaction of two liquid polymers. These balls were introduced in the 1980s. They allow the player to manipulate the number of hooks on the balls.
  • Reactive urethane – reactive urethane balls are comprised of urethane and bringing in the reactive element. These were advertised in the 1990s. They have a drier surface that not only increases the friction but also increases the potential of the ball to hook.

Apart from all of the above, the introduction of particle balls created breaking news for everyone in the later 1990s. They are known to be the most efficient as they are comprised of reactive urethane shells mixed with some microscopic particles. It is advisable to use them on the freshly oiled lanes to enhance the friction and allow more hooks to the ball.

For slightly drier lanes, using urethane shell balls is advisable as it helps in increasing the rotations of the ball. If the lanes are completely dry, plastic shell balls must be used.
