Product Description
Product Overview
Our JDB flanged graphite plugged bronze bushing (also known as flange self-lubricating copper sleeve) is manufactured from high-strength high-lead bronze / high strength brass alloy, with solid graphite plugs embedded evenly on the sliding surface. It works without oil refueling, ideal for heavy load, low speed, oscillating motion and occasions where oil lubrication is hard to realize. The integrated flange design can bear both radial load and axial thrust load, easy for positioning and installation.
This flanged self-lubricating bearing can replace traditional rolling bearings in many harsh working conditions, widely adopted in mold, hydraulic cylinder, automation machinery, construction machinery, textile equipment and automotive industry.
Key Features
✅ Self-lubricating performance: Embedded solid graphite provides continuous lubrication, no frequent oil supply required
✅ High load capacity: High strength bronze base, withstand heavy static & dynamic load
✅ Low friction coefficient, excellent wear resistance
✅ Flange one-piece structure: Radial + axial bearing capacity, anti-offset, simple mounting
✅ Wide working temperature range: -40℃ ~ +300℃
✅ Customizable: Inner diameter, outer diameter, length, flange size, graphite density can be customized
✅ No oil pollution, suitable for clean environment such as food and medical equipment
Application Fields
- Injection molds, die casting molds
- Hydraulic cylinders & pneumatic equipment
- CNC machine tools, automation assembly line
- Construction machinery, excavator hinge joints
- Packaging & textile machinery
- Automotive, new energy equipment
- General industrial machinery
