There are two types of bearings:
– Plain bearings – sliding contact between shaft and bearing
– Rolling bearings – contact roll over ball or roller between shaft and bearing
Bearings Oil-lubricated bearings: White metal, copper, lead alloys, etc.
Air bearing: Used in applications with high running precision and low friction.
Magnetic bearing: The shaft is supported by using magnetic force.
Self-lubricating bearings: Plastic bearings, solid lubricating bearings, etc.
