Description

Our Self-Lubricating Copper Split Wrapped Bronze Bushings are engineered for automotive engine and motor applications requiring minimal maintenance and compact installation. Featuring a split-sleeve design for easy assembly, a bronze-wrapped surface for wear resistance, and embedded solid lubricants for zero-maintenance operation, these bushings excel in high-temperature, high-vibration environments.

Key Features & Benefits

1.Self-Lubricating Technology

  • Embedded Lubricants: Graphite or PTFE particles within the bronze layer reduce friction (μ 0.08–0.12) without external grease.
  • Dry-Running Capability: Maintains performance in oil-free conditions, ideal for sealed engine compartments.

2.Split-Sleeve Design

  • Easy Installation: Radial assembly eliminates shaft disassembly.
  • Adjustable Fit: Compensates for misalignments up to ±0.03mm.

3.Bronze-Wrapped Copper Base

  • Material Science: Copper substrate (90% Cu) wrapped with a 0.5–1.0mm bronze layer (CuSn8).
  • Heat Dissipation: Copper’s high thermal conductivity (385 W/m·K) prevents overheating.

4.Automotive-Grade Durability

  • Temperature Resistance: Operates up to 200°C without deformation.
  • Vibration Resistance: Withstands engine frequencies up to 5,000 RPM.

5.Factory-Direct Advantages

  • Cost Efficiency: 30–50% lower pricing vs. distributors.
  • Custom Diameters: Precision-machined to 8–50mm (ID/OD customizable).
  • Rapid Prototyping: Samples within 7 days for testing.

Applications

  • Automotive Engines: Camshaft bushings, crankshaft bearings, turbocharger mounts.
  • Electric Motors: Rotor bushings, gearbox assemblies.
  • Hybrid Vehicles: Battery cooling fan bearings, e-motor mounts.
