Bimetal Bush Bearing Engine Shaft Bush Manufacturer Brake Shoe Bushing

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.
