Why Do Caster Wheels Wobble?

If your casters wobble, it’s a good idea to check for the excessive caster. Excessive caster causes the wheel to shimmy out of center and slant slightly in the other direction. The centering forces create a shimmy that motorcyclists call “the death wobble.” This shaky sensation is very frightening and only goes away when you slow down and reduce speed.

Impact loading causes caster wheels to wobble

Caster wheels can wobble due to a variety of factors. Some of these factors are caused by improper lubrication of the wheels. If your casters are wobbly, make sure to lubricate them at least five minutes before use. Improper lubrication of heavy duty casters can put the products or operation of your business at risk. This article will explore some of the more common causes of wobbly casters and ways to prevent them from happening.

In addition to impact loading, high speeds and misalignment can also cause caster wheels to wobble. Casters can also suffer from flutter when their swivels become loose or worn out. If you experience a caster flutter, be sure to take the proper steps to remedy the situation. Improper caster operation can cause the wheels to lose traction and can result in an accident.

The improper caster may cause the wheel to wobble due to a lack of balance in the suspension system. Specifically, the excessive caster can cause the wheel to move away from its center. This can cause the wheel to shimmy and wobble. Motorcyclists refer to this as a “tank slapper,” and it is a frightening experience. Only when you slow down do you see the wobble disappear.

Extending the lead reduces caster flutter

One simple way to minimize caster flutter is to extend the lead of your cart. This will result in a larger angle for the forks, which will relieve stress on your casters and employees. Be sure to adjust the weight of the load to compensate for the increased angle. Then, you can check your casters for excessive flutter. This is a quick fix, but be sure to consult your manufacturer before making any modifications.

Caster flutter is a symptom of misaligned wheels. They will flutter at a particular velocity and natural frequency. Industrial caster wheels are not balanced. To solve this issue, you can extend the lead and increase the wheel’s composition. To make things worse, you may be tempted to add more weight to the caster wheel. But this method is not recommended in all cases.

Dial indicator

If you’re working with your skateboard, you should invest in a dial indicator to accurately measure caster flutter. These tools offer easy-to-read quantitative readings of actually measured deviations, allowing you to make comparisons and gauge the quality of your parts. They feature graduated scales with red and green sections to easily read deviations.

The needle in these instruments can indicate the quality of a part without interpretation, while a good indicator will also show if a part is trending towards its tolerance limits. The two most common types of indicators are dial indicators and test indicators. The latter is more commonly used in the manufacturing industry, but it’s worth noting that it’s equally as useful in measuring caster flutter.


They differ in a number of other ways. Dial indicators have a smaller lever that fits into tighter places, while test indicators can’t measure holes in the material they’re designed to measure. They’re also much smaller than dial indicators and may not be as accurate for measuring deformable materials.

A dial indicator is a must-have tool for calculating caster flutter. They have two different styles, the standard model and the dial test indicator. Standard models feature a circular dial with numbers and a pointer hand. These indicators have a metallic sensor in the bottom of the device. Indicators are available for under $30. Indicators come in a variety of sizes and price ranges, and can be used for a variety of applications.
