High Quality OEM Undercarriage Parts Carrier Roller Support Roller For Excavator Bulldozer Loader
Structure of carrier roller/support roller:
Wheel Body :Rolls directly in contact with the track chain, supporting upper track weight and resisting heavy abrasion, impact and deformation for smooth track operation.
Wheel Axle: Firmly fixed on the track frame, acting as the stable support shaft to bear heavy loads and keep the roller assembly positioned without loosening.
Bearing: Built-in precision tapered roller bearings to ensure flexible rotation, reduce friction and withstand heavy working loads.
Floating Oil Seal: Provides excellent anti-silt, anti-dust and oil-leakage performance, blocking mud and sand to protect internal parts and lubrication.
End Caps and Sealing Rings: Form a reliable multi-layer sealing system to prevent oil leakage and impurity ingress, keeping internal components well-lubricated and durable.
How to select a carrier roller for your excavator/bulldozer/loader ?
When you select a carrier, it is important to select according to your excavator's brand and model.
6 tons, 13 tons, 20 tons, and 30 tons cannot be mixed, as the size, shaft diameters, and installation distances of these carrier rollers are different. The groove spacing of the carrier roller must be consistent with the track pitch, otherwise it is very easy for the chain to get stuck, wear out quickly, and fall off easily.
