Advantages

Pure Copper Alloy Bushing

Unlike conventional steel bushings, we utilize pure copper alloy bushings with exceptional self-lubricating properties and impact toughness. The copper bushing acts as a sacrificial wear component, effectively protecting the more expensive roller shaft from damage. Even under marginal lubrication conditions, the copper alloy maintains a low friction coefficient, preventing seizure between the shaft and roller body.

Advanced Sealing System

The sealing system combines precision-engineered floating seals with imported O-rings. This robust configuration maintains elasticity across a wide temperature range—from -40°C to 200°C—effectively preventing the ingress of mud, sand, and debris while retaining lubricating oil within the roller cavity. The reliable seal ensures long-term performance even in wet, muddy, or dusty construction environments.
