Product Description
Product Overview
This flanged graphite bronze bushing (also named flanged oilless self-lubricating bearing) adopts high-strength bronze alloy as base material, with solid graphite plugs embedded on the sliding surface. It works without oil lubrication under heavy load, high temperature, low speed, reciprocating motion and other harsh working conditions.
The integrated flange design provides axial positioning and thrust load bearing capacity. Precisely machined mounting holes make installation fast and stable. It is widely used in automation equipment, injection molds, hydraulic cylinders, engineering machinery, machine tools and other industries, replacing traditional oil lubricated bearings and reducing maintenance cost.
Key Features
✅ Self-lubricating Performance: Embedded solid graphite works as lubricant, no need for oil supply, suitable for oil-free or difficult oiling scenarios.
✅ High Load & Wear Resistance: High strength bronze substrate offers excellent compressive strength and anti-wear property, long service life.
✅ Wide Temperature Range: Stable performance from low temperature up to high temperature environment.
✅ Low Friction Coefficient: Reduce friction heat, avoid shaft seizure.
✅ Flange Integrated Structure: Bear radial load and axial thrust load at the same time; mounting holes for easy assembly.
✅ Customizable: Support custom ID, OD, length, flange size, graphite distribution according to drawings.
Application Scenarios
- CNC machine tools, automation linear motion equipment
- Plastic injection molds, die casting molds
- Hydraulic cylinders, construction machinery, excavator hinge parts
- Packaging & textile machinery, automotive new energy equipment
- Heavy-duty low-speed rotating mechanism
