Product Description

Product Overview

This bi-metal sliding bushing is manufactured with a sintered composite structure: low carbon steel backing bonded with copper alloy lining. The unique wavy seam design on the outer surface guarantees powerful bonding between steel and copper layers, preventing delamination under heavy load. Precisely machined oil holes are available to store lubricant and form a stable oil film during operation, greatly reducing friction and wear.
It is a preferred heavy-duty sliding bearing widely adopted in engine connecting rods, piston pins, construction machinery, hydraulic cylinders, automotive transmissions and other oscillating & rotating motion applications. Custom sizes based on drawings or samples are supported.

Key Features

✅ High Load & Impact Resistance
Solid steel base provides high mechanical strength; copper alloy inner layer absorbs impact force, suitable for heavy-duty working conditions.

✅ Excellent Wear Resistance & Low Friction
Sintered copper alloy lining delivers good anti-friction performance, reduces shaft abrasion and extends service life under continuous lubrication.

✅ Strong Bonding Structure
Special wavy interlocking structure between steel and copper layers avoids separation under cyclic load and vibration.

✅ Precision Machining
CNC turning, fine boring & surface finishing. Strict tolerance control for interference press fit, smooth inner bore surface Ra ≤0.8μm.

✅ Customizable Options
Custom ID, OD, length, oil hole position, oil hole quantity and oil groove design to match your equipment requirements.

✅ Wide Compatibility
Works well with mineral oil lubrication, suitable for automotive, engineering machinery, agricultural machinery and hydraulic systems.

Application Scenarios

- Automotive engine connecting rod, piston pin
- Excavators, loaders and other construction machinery hinge points
- Hydraulic cylinders & hydraulic power units
- Truck & agricultural machinery transmission assemblies
- General industrial heavy-duty sliding mechanisms
