Bimetal Bearings|Self-lubricating Bearings-bronzelube.com

Low Maintenance

Bimetal Bushing Manufacturer,Steel backing bronze plated bushing lead free with CuSn8Ni Sliding layer can be machined with lubricating grooves and/or with grease indents.High load capacity.

Bimetal bearing products structure of low carbon steel backing and bronze alloy (CuSn8Ni1) sliding layer. This product is lead-free and RoHS compliant. To decrease abrasion, oil grooves can be formed on the surface of alloy. According to the requirement, the steel back can be plated with tin plating.

MATERIAL AND COMPOSITION

Materiai:Steel+CuSn8Ni (Steel+lead-free bronze+solid Lubricant RoHS)

Based on high quality low carbon steel sintering process lead free bronze alloy and solid lubricant on the surface,

reduce the wear factor. The solid lubricant supplying the lubricant source when working. Compare with

traditional bi-metal material, it not only meets the lead free requirement, also can achieve excellent wear resistance, suitable for the condition of boundary lubrication and fluid lubrication.

BI-METAL BEARINGS STRUCTURE

1. Sinter lead-free bronze powder, provides bearing performance, have good wear resistance and excellent load carrying capacity.

2. Steel backing, provides exceptionally high load carrying capacity and excellent heat dissipation.

BI-METAL BEARINGS FEATURE

The lead-free bronze layer with steel support offers high specific loads, excellent fatigue strength in dynamic and impact load applications, superior performance under oscillating movement, indentations and grooves in the bearing lining provide a grease reservoir and therefore allow prolonged re-greasing intervals.
