Product Description
Product Overview
Our JF800 bimetallic bushing is a high-performance composite sliding bearing, manufactured by metallurgically bonding a low-carbon steel backing with a bronze alloy lining. The inner surface is precision machined with oil pockets to store lubricant, delivering outstanding wear resistance and load capacity under heavy-duty working conditions.
This bi-metal bearing can be customized with flanges, oil holes and lubrication grooves to match your equipment requirements. Widely adopted in construction machinery, hydraulic cylinders, trucks, automotive assemblies and agricultural machinery.
Key Features
✅ High load capacity & excellent impact resistance, steel base provides strong structural rigidity
✅ Bronze inner layer with oil pockets, retains lubricant and reduces friction & wear
✅ Good fatigue strength, stable performance under alternating heavy loads
✅ Compatible with oil or grease lubrication; optional pre-lubrication design
✅ Customizable dimensions, flange, oil hole and groove processing available
✅ Strict quality control, ISO standard tolerance, stable batch consistency
Application Scenarios
- Construction machinery: excavator hinge points, boom & connecting rod bushes
- Hydraulic equipment: hydraulic cylinder guide bushes
- Automotive & truck: engine, camshaft, starter motor components
- Agricultural machinery, gearboxes, heavy-duty automation equipment
- General heavy mechanical articulated joints
