Wrapped Aluminium Steel Shaft Bimetal Bearing Bushes Tin - Plated AlSn20Cu

Wrapped bushing steel aluminum AlSn20Cu Bimetal Bearings is a maintenance-bound composite sliding bearing. Oil or grease lubrication is necessary. Standard white metal bearing, Heavy maintenance.For high rotational speeds in a sealed and oil-lubricated application.Get in touch ...

High percentage of tin with aluminum alloy bushing is backing on low carbon steel, pressed with AlSn20Cu as liner. It has fairly good performance in anti-fatigue and good load capacity, anti-corrosion and smooth sliding movement.

It usually used as engine bearing with middle or low power, air compressor bushing. It is a good substitution for Babbit material.

Liner material: AlSn20Cu

Load capacity: 30N/mm2

Temperature Max: 150℃

Liner hardness: HB30~40
