Movement of spherical plain bearings

Combination of slide bearing: a Plastic bearing formed by the combination of bearing structure in the above-mentioned two or more of rolling bearings. Such as needle roller and cylindrical roller thrust bearings, needle roller and thrust ball bearings, needle roller and angular contact ball bearings, etc..
Other bearings: Rolling of the other structures in addition to the above.
Plain bearings: plain bearings, regardless of inside and outside the ring rolling element, usually made ​​of wear-resistant materials. Commonly used in low-speed, heavy and filling oil and difficult to maintain the mechanical rotating parts.
Rolling mill bearings: rolling mill bearings are generally only used to bear radial load, compared with the same size deep groove ball bearings have a greater radial load capacity, speed limit close to the deep groove ball bearings, but with such bearings with shaft shell holes higher processing requirements, allows the axis of the inner ring and outer ring axis tilt is very small (2 ° -4 °), two axis tilt beyond the limits of the roller and ring raceway contact situation will be worse, seriously affect the load bearing capacity, reduce bearing life. Bearing such as need to install the host components to withstand the axial load, and only used at the same time other types of bearings to bear under the premise of the axial load before use.
The general said the bearings for rolling bearings (ball and roller bearing). Rolling is the sliding friction between the operation of the shaft and shaft seat into rolling friction, thereby reducing the friction loss of a precision mechanical components. Rolling bearing is usually from the outer ring, inner ring, rolling element and cage. Rolling maintenance, reliable, good starting performance, higher carrying capacity at medium speed. Compared with sliding bearings, rolling bearings radial size, poor damping capacity, high speed, low life, sound.
