Custom Copper Inner-Lined Bushings for Heavy Industrial Machinery
MetalKeen manufactures custom copper inner-lined bushings designed for demanding industrial applications requiring excellent wear resistance, low friction, and long service life.
Our bushings combine a durable structural body with a precision-machined copper alloy bearing surface. The copper inner lining provides excellent sliding performance, thermal conductivity, and resistance to wear, helping protect shafts while extending equipment life. Copper and bronze alloy bushings are widely used in heavy-load, low-speed, and oscillating applications where rolling bearings are not suitable.
Manufactured according to customer drawings or OEM specifications, MetalKeen provides complete machining, oil groove processing, lubrication hole machining, assembly, and quality inspection services.
What Is a Copper Inner-Lined Bushing?
A copper inner-lined bushing is a plain bearing consisting of a structural outer body with a copper alloy bearing surface that supports rotating or oscillating shafts. The copper lining reduces friction, distributes loads, absorbs vibration, and improves wear resistance, making it suitable for heavy-duty industrial equipment.

Frequently Asked Questions
Why choose a copper-lined bushing instead of a rolling bearing?
Copper-lined bushings perform exceptionally well in heavy-load, low-speed, shock-load, and contaminated environments where rolling bearings may have reduced service life. They also provide excellent vibration damping and shaft protection.
Can MetalKeen manufacture custom bushings?
Yes. We manufacture according to customer drawings, CAD files, or samples, including customized lubrication grooves, flange designs, and special dimensions.
Which industries commonly use copper alloy bushings?
Our bushings are widely used in paper mills, hydraulic systems, mining equipment, marine machinery, steel plants, pumps, and construction machinery.
Can lubrication grooves be customized?
Yes. Straight grooves, spiral grooves, figure-eight grooves, annular grooves, oil holes, and grease pockets can all be machined according to your operating requirements.
