Rollers
What is a Track Roller?
The track roller is an essential component of the undercarriage system in crawler-type construction machinery. Its primary function is to support the weight of excavators and bulldozers, ensuring the smooth movement of tracks along the rollers.
Track rollers not only bear the machine’s weight but also guide the track along the rail link or track shoe surface, preventing lateral slippage. During turns, they facilitate track movement on the ground. Operating in harsh conditions—mud, water, dust, and heavy impacts—track rollers require wear-resistant rims and reliable sealing for durability and performance.
Their role is crucial in transferring the machine’s weight to the ground while maintaining stability and alignment. To withstand extreme working conditions, track rollers must feature wear-resistant rims, robust bearing seals, and low rolling resistance.
Siderwin is one of the leading track roller manufacturers and suppliers in China.
Construction Dozer Rollers
Rollers Features
- Undercarriage rollers are sealed for life using the most advanced sealing system solutions.
- Mining dozer roller shells are differential quenched to provide high wear resistance at the rail diameter and high mechanical strength at the inner diameter to avoid any kind of deformation under load.
Construction Excavator Rollers
Rollers Features
- Rollers for medium-range excavators are sealed for life using the most advanced sealing system solutions.
- Roller shells are differential quenched to provide high wear resistance at the rail diameter and high mechanical strength at the inner diameter to avoid any kind of deformation under load.
