What Causes Bowling Balls to Crack?

Bowling is a beloved sport and leisure activity enjoyed by many worldwide. As such, it’s important for bowlers to ensure that their equipment remains in good condition. Unfortunately, bowling balls are prone to cracking due to several factors and conditions. In this blog post, we’ll explore some of the most common reasons why bowling balls crack or become damaged over time.

Physical Damage Caused by Impact

The most obvious cause of damage in your bowling ball is the physical impact of repeatedly throwing or rolling it on a hard surface. Since even the toughest polyurethane coverstock can’t withstand infinite force, repeated impact will eventually cause micro-cracks in its surface that could lead to larger cracks down the line if left unchecked. To minimize this kind of damage, it’s best practice for bowlers to use an appropriate lane conditioner at all times and avoid dropping or throwing their balls too hard against any surfaces that may be particularly rough or rigid.

Damage From Age & Temperature

Another major factor causing bowling ball cracks is age and temperature changes over time – especially when stored improperly during seasons where temperatures fluctuate drastically between cold and hot summer days. This can cause the plastic molecules used in polyester resin covers – which make up much of a modern-day bowling ball – to weaken over time, leading them susceptible to cracking with more aggressive throws as well as shortening their lifespan overall if not taken care of properly. To avoid these kinds of damages, always keep your equipment out of direct sunlight and extreme temperatures as much as possible!


Cracking is one issue every bowler should know about – whether you’re just starting out or have been playing for years! Fortunately, there are plenty of ways you can prevent your ball from falling victim to wear-and-tear caused by physical impact, age, or unfavorable temperatures. Just remember to take proper care of your equipment so you won’t end up having a cracked ball syndrome!
