Product Description
JF800 Bimetallic Sliding Bushing
Steel Bronze Composite Bearing with Custom Oil Grooves
Heavy Load, Wear Resistant, For Hydraulic & Construction Machinery
Product Overview
JF800 bimetal bushing is a composite sliding bearing made of low carbon steel back sintered with CuPb10Sn10 bronze alloy layer. The inner surface is precision machined with oil grooves to store lubricant and form stable oil film during operation.
It combines high mechanical strength from steel substrate and low friction, good wear resistance from bronze layer. This type of bimetal bearing is widely used for heavy-duty rotary and oscillating motion under grease or oil lubrication. Custom oil groove structure, shoulder step and dimension are available according to drawings.
Core Advantages
✅ High Load Capacity
Steel backing provides strong structural support, withstand heavy static & dynamic load for engineering equipment.
✅ Excellent Wear Resistance
Homogeneous sintered bronze alloy layer, good anti-friction performance, extend service life under continuous swing motion.
✅ Custom Oil Groove Design
Precision internal oil grooves reserve lubricant, maintain continuous oil film, reduce friction and seizure risk.
✅ Flexible Customization
Custom ID, OD, length, shoulder step shape, oil groove pattern, anti-rust surface treatment are acceptable.
✅ Stable & Reliable
Strict CNC machining, consistent dimension tolerance, ISO9001 quality control for mass production.
Application Scenarios
Hydraulic cylinders & hydraulic systems
Construction machinery, excavators, loaders
Automotive chassis & transmission assemblies
Agricultural machinery
Mining equipment & lifting devices
Gearbox, general industrial machinery
