What are Bowling Balls Made Of: A Complete Guide

What are Bowling Balls Made Of

Bowling balls have undergone a fascinating evolution in materials throughout history.

  • Early bowling balls: Centuries ago, bowling balls were simply made from hardwood, particularly a wood called Lignum vitae. This wood was chosen for its durability and density.

  • Rubber revolution: In the early 1900s, rubber became the material of choice for bowling balls. This marked a significant improvement in performance and popularity of the sport.

  • The rise of polyester: The 1970s saw the introduction of polyester bowling balls. These balls were lighter, easier to control, and more affordable than their rubber predecessors. They quickly became the standard for recreational bowling.

  • Urethane and beyond: In the 1980s, urethane balls emerged, offering even more control and hook potential for experienced bowlers. Today, reactive resin balls are the top choice for professional bowlers, providing the most grip and hooking action on the lane.

Modern bowling balls are actually made of two main parts:

  • The core: This is the inner part of the ball, typically made from a dense material like resin combined with heavy substances such as barium or bismuth graphite. The core’s weight and shape significantly impact the ball’s weight distribution, influencing its rolling characteristics and ability to hook.

  • The coverstock: This is the outer shell of the ball, made from various materials like polyester, urethane, or reactive resin. The coverstock material determines the ball’s friction on the lane, affecting how much it hooks and skids. Read about How Long is a Football Game

Traditional Materials Used in Bowling Balls


Rubber was one of the earliest materials used in bowling ball construction. It provided durability and a consistent roll but lacked the performance capabilities of modern materials. Discover about Pickleball vs Tennis


Plastic became popular due to its affordability and durability. It offered a smoother roll and better control, making it a favorite among casual and professional bowlers alike.


Urethane revolutionized the industry with its increased hook potential and versatility. It allowed bowlers to achieve greater control and power, leading to improved scores and gameplay.

Evolution of Bowling Ball Composition

Reactive Resin

Reactive resin bowling balls introduced enhanced friction capabilities, providing increased hook potential on various lane conditions. This innovation revolutionized the way bowlers approached the game.


Particle bowling balls incorporated additives to the coverstock, creating additional traction on oily lanes. This technology further expanded bowlers’ options and strategies on challenging lane conditions.

Solid Urethane

Solid urethane bowling balls offered a predictable motion and smooth backend reaction, making them suitable for a wide range of bowlers and lane conditions.

Modern Bowling Ball Construction

Modern bowling balls feature a combination of advanced materials and design elements.


The coverstock of a bowling ball plays a crucial role in its performance. Manufacturers offer a variety of coverstock materials, each with its unique characteristics and benefits.


The core of a bowling ball determines its weight distribution and overall motion on the lane. Different core designs cater to varying playing styles and lane conditions.

Weight Block

The weight block influences the ball’s overall stability and hook potential. Bowlers can choose from a variety of weight block configurations to suit their preferences and playing conditions.

Factors Influencing Bowling Ball Composition

Several factors influence the choice of bowling ball composition for individual bowlers.

Lane Conditions

Bowlers must consider the oil patterns and friction levels of the lanes when selecting a bowling ball.

Bowler’s Style

Each bowler has a unique throwing style that may require specific ball characteristics for optimal performance.

Skill Level

Beginners may prefer more forgiving bowling balls, while advanced bowlers may seek higher-performance options to match their skill level.
