Caterpillar D3C Track Roller Bottom Roller OEM Quality Bulldozer Part

Cylindrical elements are indispensable components of conveyor systems, available in various models and readily supplied in abundant quantities. These components reliably bear the combined load of the conveyor belt and transported materials. Representing 35% of a conveyor system's total cost and generating over 70% of operational friction, their quality is critical. Available in both metallic and polymeric material options.

Our track rollers utilize premium materials including 40Mn2, 40MnB, and 50Mn, carefully selected for specific working conditions. Each component undergoes:

• Precision forging and normalization
• Overall heat treatment achieving surface hardness of HRC52-60
• Hardened layer depth exceeding 7-10mm (HRC45)

This manufacturing process ensures exceptional durability with high impact resistance and superior surface wear resistance on contact surfaces.

Featuring high-quality floating seals and a robust lubricating system, these rollers perform reliably in severe conditions ranging from -45℃ to 120℃ while requiring zero maintenance.
