What Is Inside A Bowling Ball? Things To Know ( 2023 )

Most people don’t consider what is inside a bowling ball when they first pick one up. Given that the ball is rather hefty, it is most likely solid throughout.

Is it true, though? You might be shocked to learn what constitutes a bowling ball’s inside. And that’s what this post will look into.

What Is Inside a Bowling Ball

The coverstock and the inner-core materials that make up a bowling ball can be seen as two separate parts. The majority of materials used to make bowling balls are polyurethane-based goods.

However, the industry uses the terms plastic, urethane, reactive resin, hybrid reactive, and particle materials to describe different coverstock mixes.

Typically, reactive resin coverstocks are found in general performance range bowling balls between the weights of 12 and 16 lbs. while hybrid or particle coverstocks are found in pro performance range bowling balls between the weights of 12 and 16 lbs.

Naturally, the coverstock plays the largest role in choosing the best ball for you, but don’t discount the significance of the inner core designs. Manufacturers will create urethane and polymer-based cores in a variety of densities, forms, and sizes so the final product will reliably alter the ball’s overall motion as it travels down the lane.

What’s Inside a Cheap Bowling Ball?

A low-density substance, such as polyester or rubber of poorer quality, may be used in the core of a budget bowling ball. The coverstock might also be constructed from a lesser-quality material, such as plastic, which could not be as durable or effective as more expensive coverstocks made of reactive resin or urethane. Additionally, inexpensive bowling balls could not have extra features like vibration-dampening mechanisms, weight blocks, or asymmetrical weighting.

Are bowling balls created equally? 

Not all bowling balls are made the same. Bowling balls can have a variety of qualities and attributes since different manufacturers produce them using various materials and manufacturing techniques. For instance, while certain bowling balls may be more durable than others, others may be more reactive on the alleys. Additionally, different coverstocks, core designs, and drilling patterns may be used to create bowling balls in a variety of weight ranges. The performance of the ball on the lanes can be impacted by all of these variables.

Are expensive balls created differently? 

Bowling balls that cost a lot of money are frequently produced differently than cheaper balls. They may make advantage of better materials and more sophisticated production techniques, which might improve performance on the lanes.

More sophisticated and responsive coverstock may be found in more expensive balls, which can increase hook potential and improve responsiveness on the lanes. Additionally, they could have more intricate core designs, which might lead to a lower RG (Radius of Gyration) and higher differential, making the ball more aggressive and responsive.

Additionally, certain expensive bowling balls could be specially drilled to meet each bowler’s unique requirements, which could have an impact on the ball’s performance.

It’s important to keep in mind, though, that a bowling ball’s cost is not necessarily a good indication of its performance or quality. While some more costly balls might not perform as well as others, certainly less expensive balls might still provide good performance. It’s critical to select a ball based on your unique requirements and preferences rather than just selecting the most costly choice.

What is the different ball made of?

Rubber, plastic, and urethane are just a few of the materials that may be used to create bowling balls.

The original ball used in the sport was a rubber bowling ball. They are renowned for their endurance and are constructed from a variety of rubber compositions. They don’t perform quite as well as other kinds of balls, though.

The low-friction surface of thermoplastic bowling balls, which are constructed of this material, makes them popular. They are often utilized by bowlers with a straighter ball motion and are less reactive on the lanes than other kinds of balls.

The synthetic substance used to make urethane bowling balls is more reactive on the alley than plastic. They perform better and are also more resilient than rubber balls. Professional bowlers and those with a more ferocious ball motion frequently utilize them.

In addition to varied materials, bowling balls may also have various coverstock and core configurations, which may have an impact on how well the ball performs on the lanes. The coverstock of the ball refers to its exterior covering that makes contact with the lanes, while the core design describes how the ball’s interior weight is distributed.

How Does a Bowling Ball’s Construction Affect Gameplay?

There are various ways in which a bowling ball’s design might influence gameplay:

  • Coverstock: The outside layer of the ball that makes touch with the lanes is known as the coverstock. The friction and reactivity of the ball on the lanes might vary according to the coverstock. A more reactive coverstock will have a stronger reaction on the lanes and higher hook potential, whilst a less reactive coverstock will have less hook and a straighter reaction.
  • Core Design: The interior weight distribution of the ball is described by the core design. A ball with a greater RG and lower differential will be less aggressive and offer a straighter trajectory than one with a lower RG and higher difference.
  • Drilling Layout: The location of the finger and thumb holes on the ball is referred to as the drilling layout. The reactivity of the ball on the lanes and the bowler’s ability to control the ball may both be influenced by a drilling arrangement that is tailored to a particular bowler’s hand size and throwing technique.
  • Weight: There are many weight ranges for bowling balls, which might impact a bowler’s capacity for power production and ball control. Although it will take more work to toss a heavier ball, it can produce greater force and have a larger impact on the lanes. Although it will be simpler to toss a lighter ball, it could not have as much power or response on the lanes.
  • Construction in general: The ball’s resilience, reactivity, and performance may all be impacted by the caliber of the materials used and the production method. Most generally, more expensive balls are created with superior materials and manufacturing techniques, which can result in improved performance and longevity.

Final thoughts: 

Every bowler has a unique style and set of requirements, so what works for one person may not work for another. Therefore, it’s crucial to try out many balls and select the one that best meets your unique requirements and tastes.
