Bearings

Bearings are mechanisms that are used to support and rotate various parts and mechanisms. They can be ball, roller or needle, depending on the type of mechanism they support.

Ball bearings consist of two rings, between which there are many balls. These balls support the shaft and ensure its rotation. Ball bearings are widely used in various mechanisms such as electric motors, pumps, compressors and others.

Roller bearings are also used to support shafts. They consist of an inner and an outer ring, between which there are rollers. The rollers support the shaft and allow it to rotate without friction. Roller bearings are commonly used in heavier machinery, such as machine tools, automobiles, and other vehicles.

Needle bearings consist of an outer and an inner ring, between which the needles are located. The needles support the shaft and allow it to rotate. Needle bearings are used in small mechanisms where high precision and small size are required.
In general, bearings are important elements of many mechanisms and are used to ensure their efficient operation.
