Track roller must hold the weight of excavator and bulldozer equipments along with load capacity, it requires precision, strength and durability.

Our track roller for excavators are specially designed, engineered and manufactured for high impact applications. Bulldozer bottom rollers are designed for applications that call for the maximum wear resistance.

ROLLERS: Developed with the highest-quality materials in an efficient, quality controlled manufacturing environment. we serves the heavy equipment and industrial markets with track and carrier rollers for machinery such as excavators, bulldozers, mini excavators and skid steer loaders. Our roller offering is one of the most complete in the world, with hundreds of line items from which to choose.

We use good material to ensure quality and consistency. Our heat treatment process provides hardness in high wear areas, and elastic core to resist shock and impact loads. With strict quality management, we produces effective and stable excavator and bulldozer undercarriage parts meet customer’s demand.

Wr collected professional undercarriage parts catalog from OEM suppliers, which gathered almost models part number and sizes, formed our special part number system and convenient for you to check your parts. Also we have some special machine model parts sizes, which will provide specialize production for your own machine. By the way, producing according to customer drawing is another way we make special service for customers. Caterpillar Rock Chisel Tooth

Track rollers
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.).

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.

Rollers failures
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 301.7D

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.
