bearing [ imenica {mehanika} ]
Device used in a machine to allow free movement between two parts, typically the rotation of a shaft in a housing. Ball bearings consist of two rings, one fixed to a housing, one to the rotating shaft. Between them is a set, or race, of steel balls. They are widely used to support shafts, as in the spindle in the hub of a bicycle wheel.
The sleeve, or journal bearing, is the simplest bearing. It is a hollow cylinder, split into two halves. It is used for the big-end and main bearings on an automobile crankshaft.
In some machinery the balls of ball bearings are replaced by cylindrical rollers or thinner, needle bearings.
In precision equipment such as watches and aircraft instruments, bearings may be made from material such as ruby and are known as jewel bearings.
For some applications bearings made from nylon and other plastics are used. They need no lubrication because their surfaces are naturally waxy.
