It also called Excavator bottorm roller and excavator lower roller is composition of two pieces of forged semi-roller and the roller body is welded by CO2 automatic welding.
Excavator track roller also called Excavator bottorm roller and excavator lower roller is composition of two pieces of forged semi-roller and the roller body is welded by CO2 automatic welding.
Each excavator bottom roller shaft is machined by the utilization of the most modern technological advances known to the industry, Grinding and finishing methods ensure mirror like finish and tempering with medium to low frequency heat treating equipment guarantees maximum strength.
Maximum life
Each excavator lower roller shell is carefully heat treated to ensure long wear life and stress resistance.
Precision care
Each track roller is precision machined to house special high impact low wear bimetal bushings.
In the process of assembly of roller, the expected and reliable sealing and lubricating rotation of roller are guaranteed by testing of air pressure tightness and load-bearing rotation.

What is track roller ?
Track Rollers: The Crucial Support of Crawler Construction Machinery
Track rollers are an integral part of the chassis system in crawler-type construction machinery, serving as one of the four-wheel belts that provide essential support. Their primary role is to bear the weight of heavy equipment such as excavators and bulldozers, allowing the tracks to move smoothly along the wheels.
Function of Track Rollers
Weight Support: Track rollers support the weight of the machinery while they roll on the guide rail (rail link) or the track shoe surface, ensuring the stability of the machine during operation.
Lateral Movement Restriction: They also serve to limit the track's lateral movement, preventing side slippage which could lead to derailment.
Turning Assistance: During turns, the track rollers facilitate the process by causing the track to slip laterally on the ground, aiding in the steering mechanism of the machine.
Operating Environment of Track Rollers
Track rollers often operate in harsh conditions, such as mud, water, and dust, and are subjected to significant impacts. As a result, they require specific attributes:
Reliable Sealing: To prevent the ingress of mud and dust into the roller mechanism, which could lead to premature wear or failure.
Wear-Resistant Rims: Given their operation in challenging environments, track rollers need to have durable rims that can withstand abrasion.
Low Rolling Resistance: To enhance the machine's energy efficiency and operational capabilities, track rollers should be designed with low rolling resistance in mind.
Design Considerations for Track Rollers
When designing track rollers, the following key factors should be taken into account:
Durability: Track rollers must be robust enough to handle the rigorous conditions encountered during various types of terrain operations.
Maintenance Accessibility: The design should allow for easy inspection and maintenance to minimize downtime.
Performance Enhancement: Track rollers should be engineered to optimize rolling balance and reduce vibration, thereby improving the overall performance of the machinery.
