Track rollers /386-0791/ are an essential part of the overall undercarriage system as they carry a whole host of tracked machines. The size of the rollers is selected so that the machine can work without any problems in normal working mode. And the temperature resulting from prolonged loading is safely removed from all components (bearings, seals, etc.). Bottom Track Roller for CAT Excavator 302.4D
The maximum resistance to abrasion of the rollers is achieved thanks to appropriate castings, precise machining and induction hardening. Moreover, good parameters are obtained thanks to tempering, increasing durability and extending the life of the rollers through their even wear.
Premature failure of the rollers /386-0791/ may be caused by their uneven load. E.g. when working with rollers that are worn to varying degrees (when they were not completely replaced during repair work). CAT Track Roller 301.7D (381-3040)
What’s more, 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 track 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. Bottom Roller For CAT CAT Excavator Bottom Roller 302.4D, 386-0791
Track rollers /386-0791/ 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.
