Product Description

CARRIER ROLLER

A carrier roller, also known as a top roller or upper roller, is a component of the undercarriage of tracked machinery such as excavators, bulldozers, and other construction equipment. The carrier roller is located at the top of the undercarriage and serves to support the weight of the track chain and distribute the weight evenly across the undercarriage.

The carrier roller typically has a cylindrical shape with a bearing in the center and rotates on an axle, allowing the track chain to move smoothly and reduce friction. Carrier rollers play an important role in ensuring the stability and durability of the undercarriage and preventing premature wear and tear of the track chain.

Carrier rollers are designed to support the weight of the track chain and distribute the weight evenly across the undercarriage. They are typically located at the top of the undercarriage and serve to keep the track chain in place. Carrier rollers are also known as top rollers or upper rollers.

* Excavator carrier rollers are made of the roller body, shaft, collar, bimetallic bearings, and seal group. it is made through forging, machining, heat treatment, assembly, and painting.

* The quality and working life depend on the quality of the raw steel, the hardness of the rail surface, the depth of the hardness layer, and the quality of the seal group

ROLE OF ROLLERS

Upper rollers support the weight of the track chain and maintain proper tension, allowing the track to move smoothly along the track frame.

Upper rollers are made of high-strength steel and are durable enough to withstand the rigors of heavy-duty excavation operations.

Heavy-duty upper rollers can withstand the forces applied during operation and maintain performance for a longer period of time
Regular maintenance and timely replacement of worn rollers are essential practices.

STRUCTURE AND COMPOSITION OF CARRIER ROLLER

A typical Carrier Roller is composed of a drum, bearings, sealing device, and supporting structure. The drum is usually manufactured from high-quality alloy steel to withstand heavy loads and meet the high-strength demands of prolonged usage. Bearings are embedded within the drum to ensure smooth and unobstructed rolling. The sealing device provides effective dust and water protection, prolonging the roller's lifespan. The supporting structure connects the drum to other components of the machinery, securely anchoring it to the track chain.
