FAQ

What are the main advantages of a bimetal bearing like the AKN BM series?

Bimetal bearings combine the strength of a steel backing with the excellent anti-friction properties of a bronze or other alloy sliding layer. This results in high load-bearing capacity, good fatigue resistance, and effective heat dissipation, making them superior to monolithic polymer or bronze bearings in many heavy-duty applications.

What are the installation requirements for this 38x42x40mm plain bearing bush?

This bearing should be press-fitted into a rigid housing with an H7 tolerance. It is crucial to use a suitable mandrel that applies force only to the outer ring of the bush to prevent damage. The housing bore should be clean and free of burrs before installation.

Is this bearing pre-lubricated or does it require external lubrication?

The sliding surface of this type of bimetal bearing typically has indents or pockets to retain lubricant. While it may have a light protective coating, it is designed for operation with external lubrication (oil or grease) to achieve its maximum performance and lifespan. The lubrication regime depends on the specific application’s speed, load, and operating environment.
