Stub Axle Bimetal Bushing, Oilless Sliding Bearing Bushing, Bimetal Bush Bearing

Description

Bimetal Bush Bearings are engineered for high-load, low-maintenance environments, featuring a steel outer layer for structural integrity and a copper-alloy inner layer for reduced friction. Ideal for gearboxes, pumps, and construction equipment, these bearings offer a cost-effective alternative to solid bronze while maintaining superior performance.

Key Features & Benefits

1.Dual-Metal Construction

• Steel Back (50 HRC): Provides rigidity and load-bearing capacity up to 120 MPa.
• Copper-Alloy Lining (CuSn8/CuAl10): Self-lubricating surface with friction coefficients as low as 0.08.

2.Advanced Lubrication Design

• Porous Structure: Micro-pores retain oil for extended service life (up to 3x longer than standard bearings).
• Embedded Lubricants (Optional): Graphite/PTFE particles for dry-running applications.

3.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, threaded ends, or dual-radius profiles.

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

• Industrial Machinery: Gearboxes, hydraulic pumps, compressors.
• Automotive: Transmission systems, steering knuckles, differential assemblies.
• Construction: Excavator pins, crane mechanisms, loader arms.
• Energy: Wind turbine pitch systems, hydraulic actuators.
