Track rollers – also referred to as idler rollers – are motion transmission components designed to work with all varieties of tracks. They see use in conveyor systems, cam drives, and a wide range of similar material handling systems. Regardless of the material or machine, these components play a critical role in track and rail operations.
The rollers also degrade when driving at higher speeds for longer. Then there are leaks, from which oil leaks, which leads to incorrect lubrication of the bearings, and this leads to failure of the rollers. If the lower rollers lack the right amount of oil, the bearings get stuck and are not able to rotate around their axis inside the roller. As a result they are seriously damaged. Lower rollers with leaking or blocked bearings should be replaced immediately to prevent damage to other track components, such as the link chain, because non-rotating rollers lead to rapid wear of the track chains. This is due to an increase in the frictional force on the roller shell and the contact surface of the chains.
