What is the bearing

Bearing: the definition of bearing is a bearing parts, it can guide the axis of rotation, can also turn over the shaft parts, under the concept of bearing is very broad. Bearing can be divided into rolling bearing and sliding bearing, the most common bearing is rolling bearing, roller bearing all the rolling bearing; Sliding bearing to denote no rolling element bearings, sliding bearings are sliding bearing of the movement. The classification of the rolling bearing is mainly according to the shape, roller bearing force and structural type classification, rolling bearing structure generally consists of inner ring and outer ring, rolling body, and a cage. See below, the below indicate the bearing the name of the parts. Listed above, just three of the most common, the most commonly used single-row roller bearing, according to the number of columns, roller bearing and also can be divided into bearing, in the same set of bearings is equipped with two or several row roller. In the bearing ring or shaft, seat ring with a number of roller, roller by keeping uniform spacing, cage to prevent rolling body collide with each other, in order to reduce resistance to bearing can achieve higher speed. Classification of rolling bearings are classified by carrying the load stress direction of the bearing of the bearing, bearing ring rolling surface between the roller and the load direction and perpendicular to the plane of the center line of the bearing is called contact Angle formed by the point of view, when the contact Angle is less than 45 ° bearing is mainly for radial force, called the centripetal bearing; When the contact Angle between 45 ° ~ 90 ° when called thrust bearing. On the radial and axial please see below: the classification of the sliding bearing, mainly divided into the joint bearing and dry sliding bearing. Joints and points to the heart joint bearings, thrust joints, rod end joint device, etc. , which is divided into two major categories of lubrication and self-lubrication. Dry sliding bearing points of dry sliding shaft sleeve, sliding gasket, linear slider etc. The classification of the sliding bearing
