About Carrier Roller

Carrier rollers, located at the top of the track frame to maintain the position of the track chain, are also called top rollers or upper rollers. They are composed of a roller body, axle, and bi-metal bearings, and are part of the four main rollers along with the idler, drive sprocket, and bottom rollers. As one of the essential undercarriage parts, their main function is to support and tension the track, distribute weight evenly, reduce friction, and prevent premature wear. FridayParts carrier rollers are wear-resistant, impact-resistant, and designed to work on soft ground. Importantly, they are OEM quality and compatible with original equipment.

FAQs

What affects the quality and lifespan of carrier rollers?

Factors include the quality of raw steel, surface hardness of the rail, depth of the hardness layer, and quality of the seal group.

What's the difference between carrier rollers and track rollers?  

Carrier rollers contact the track chain to drive the track forward or backward, providing traction. Track rollers are located at the bottom of the track frame, in direct contact with the ground, supporting the track's weight and reducing friction. Track rollers have a more complex structure and stronger load-bearing capacity.

How to maintain excavator carrier rollers?

Carrier rollers, bearing lighter loads, require less lubrication and maintenance. However, they should be lubricated once with grease. If there is oil leakage, the rollers should be replaced promptly. Keep the slanting platform of the X-frame clean to prevent accumulated dirt and gravel from hindering the rollers' rotation.
