What is the function of rollers?

It is one of the four-wheel belts of the crawler-type construction machinery chassis. Its main function is to support the weight of the bulldozer and allow the crawler to advance along the wheels.

Its main function is to support the weight of the excavator and the bulldozer, so that the crawler tracks move along the wheels to complete the work.

Track rollers 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.). 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.
