Product Description
1. Material Structure
SF-2 is a two-layer composite boundary lubricating bushing designed for working conditions with thin oil or intermittent oil supply.
Backing: Low carbon steel substrate with anti-corrosion electroplating
Surface layer: Porous sintered bronze layer (0.25~0.35mm), impregnated with solid lubricant & oil storage structure
2. Material & Performance Features
Boundary Lubrication Adaptation: Bronze porous matrix can store lubricating oil, works reliably under thin oil, intermittent oil supply or grease replenishment conditions.
High Load & Wear Resistance: Sintered bronze surface with good bearing property, less adhesive wear under heavy low-speed load.
Good Embeddability & Conformability: Tolerates minor shaft surface impurities and slight misalignment, protects shaft surface.
Simple Maintenance: Periodic grease filling can greatly extend service life, lower replacement cost.
Steel Backing Reinforcement: High mechanical strength, stable dimension under heavy load.
3. Application Scenarios
Suitable for low-speed heavy-load boundary lubrication occasions. Widely used for agricultural machinery, construction equipment hinge parts, gearbox sliding sleeves, lifting machinery, conveyor equipment, general machinery pivot bushes.
