Copper Bearing

Copper Bearing (also known as Bronze Bushing) is a core wear-resistant spare part for heavy-duty automatic draught device / drawbar coupling. Made of high-strength tin bronze alloy, this sliding bushing bears radial load and absorbs impact force during towing operation. It reduces friction between pivot shaft and coupling housing, avoiding metal direct contact, extending service life of the whole drawbar assembly. Designed for heavy load, vibration and harsh road conditions of semi-trailers, dollies and tank trailers. Good wear resistance, shock resistance and corrosion resistance. Interchangeable OEM replacement part.

Key Features

1. .High strength tin bronze alloy material: Excellent load-bearing capacity, anti-impact under heavy towing shock load.
2. .Precision machining: Strict tolerance control, perfect fit for drawbar coupling pivot shaft.
3. .Outstanding wear resistance: Low friction coefficient, stable lubrication performance.
4. .Good shock & corrosion resistance: Adapt to dust, mud and variable temperature environment.
5. .Easy replacement: Standard dimension, direct replacement for worn original bushing.
6. .Optional self-lubricating graphite embedded type: For low-maintenance working condition.
