Ball BearingsFriction Resistance Is Small
- Aug 25, 2017 -

Ball bearings are a kind of rolling bearing, ball balls are fitted in the middle of the steel ring and outer steel ring, can withstand the larger load. Also known as ball bearings. Ball bearings than the journal bearing friction frictional resistance is small, so the same speed, the friction will produce a relatively low temperature. Ball bearings have a single row to the heart, double row of the spherical surface, to the heart thrust, thrust and thrust to the heart and other structural types. This kind of bearing is mainly used to bear the radial load, but also can not bear the axial load, suitable for multi-support and flexible deformation of the larger drive shaft. Two-way thrust ball bearings have two live rings, one tight ring, two rolling elements and two cage.

Ball bearings are mainly composed of four basic components: ball, inner ring, outer ring and retainer, also known as cage. General industrial ball bearings meet the AISI 52100 standard, the ball and the ring is usually made of high chrome steel, Rockwell hardness) between about 61-65. (Such as: medium carbon steel, aluminum alloy) or non-metallic (such as: Teflon, PTEF, polymer materials), and the hardness of the retainer is lower than that of the ball and the ring. Ball bearings than the journal bearing friction frictional resistance is small, so the same speed, the friction will produce a relatively low temperature.

Ball bearings have a single row to the heart, double row of the spherical surface, to the heart thrust, thrust and thrust to the heart and other structural types . ① single row radial ball bearings: compact structure, easy to use, wide application. Mainly used to bear the radial load, but also can withstand a certain amount of axial load. In high-speed devices, it can also be used instead of thrust bearings. This kind of bearing friction resistance is small, the limit speed is high, is suitable for the double rigidity big shaft.
