How to choose track rollers

1. Whether the steel grade meets the standard and the heat treatment process fails to perform well.

2. Whether corners have been cut in several important structures of the product, such as the diameter of the wheel body being reduced, the spindle becoming thinner, the length of the copper sleeve being shortened, etc.

The reduction of the wheel body diameter causes the wheel linear speed to increase, and the shaft sleeve bears more friction. The same principle applies to the thinning of the fulcrum. It will also not be strong enough to withstand the impact, causing the shaft to deform or break. The copper sleeve plays a role of friction. The copper layer must be rolled and rolled to prevent it from falling off. Normally, the copper layer must be above 0.35mm to meet the standard. Reducing the length of the copper sleeve will lose the meaning of the roller. Reducing the length is equivalent to reducing the force. area.
