Product Description
Product Overview
This split wrapped bimetal bushing (TCB300 / JF800 equivalent) is a steel-backed bronze sliding bearing. The outer layer adopts high-strength low-carbon steel, and the inner friction layer is lead bronze alloy with diamond-shaped oil pockets. The special split design allows easy installation into housing bores. It is engineered for heavy-load, low-speed and oscillating motion working conditions under boundary lubrication, widely used in construction machinery, hydraulic cylinders, automotive assemblies and general industrial equipment.
Key Features
✅ High mechanical strength: Steel backing provides excellent load-bearing capacity and impact resistance.
✅ Optimized lubrication: Diamond oil reservoirs on the inner surface store lubricant continuously, reducing friction and wear.
✅ Convenient mounting: Split wrapped structure for simple assembly, no special press-fit tool required.
✅ Stable performance: Good wear resistance and fatigue resistance under intermittent dry-running and heavy shock loads.
✅ Customizable dimensions: ID, OD, length and oil groove patterns can be produced according to drawings or samples.
✅ Optional surface treatment: Tin plating or copper plating on steel outer surface for anti-corrosion.
