Description
Our Bimetal Bush Bearings combine steel and copper alloys to deliver exceptional strength, wear resistance, and self-lubricating performance. Engineered for high-load environments like engine crankshafts, industrial gearboxes, and brake systems, these bearings feature a dual-layer structure: a robust steel back for support and a copper-alloy lining for reduced friction. Factory-direct production ensures competitive pricing and rapid customization.
Key Features & Benefits
1.Dual-Metal Layer Construction
Steel Back: Provides structural integrity under loads up to 100 MPa.
- Copper Alloy Lining: Tin/lead bronze or aluminum bronze for low-friction surfaces (friction coefficient 0.03–0.1).
- Bonding Process: Rolled or sintered composite technology ensures zero delamination.
2.Advanced Lubrication Design
- Oil Grooves & Holes: Circumferential grooves and radial oil holes (as shown in) distribute lubricant evenly.
- Edge Chamfering: Reduces stress concentration and eases installation.
3.High-Temperature & Corrosion Resistance
- Operates in temperatures from -40°C to 300°C.
- Resists corrosion from oils, fuels, and industrial solvents.
4.Custom Precision Engineering
- Machined to your specifications (ID, OD, length, flange details).
- Supports special designs like stepped sleeves, dual-radius profiles, and threaded ends.
5.Factory-Direct Advantages
- Cost Efficiency: 30–50% lower pricing vs. distributors.
- Quality Control: ISO 9001-certified production with material traceability.
- Rapid Prototyping: Samples within 7 days for testing.
Applications
- Automotive: Engine crankshaft bearings, connecting rod bushings, brake caliper guides.
- Industrial Machinery: Gearbox bearings, hydraulic pump sleeves, compressor shafts.
- Heavy Equipment: Excavator pin bushings, mining machinery joints, agricultural harvester components.
- Marine: Propulsion system bearings, winch assemblies, deck machinery.
