Bearing classifiexcavatorion
sliding bearing
Plain bearings are not made of internal or external rollers, and are usually made of wear-resistant materials. It is often used in low speed, light load and lubriexcavatoring oil and difficult to maintain mechanical rotation parts.
Joint bearing
The sliding contact surface of the joint bearing is spherical, which is mainly applicable to swing motion, tilt motion and rotation motion.
Rolling bearing
Rolling bearings are divided into centripetal bearings and thrust bearings according to their load directions or nominal contact angles. The radial contact bearing is a centripetal bearing with a nominal contact angle of 0, and the centripetal angular contact bearing is a centripetal bearing with a nominal contact angle greater than 0 to 45. The axial contact bearing is a thrust bearing with a nominal contact angle of 90, and the thrust angle contact bearing is a thrust bearing with a nominal contact angle greater than 45 but less than 90.
According to the shape of rolling body, it can be divided into ball bearings and roller bearings. Roller bearings are classified according to roller types: cylindrical roller bearings, needle roller bearings, tapered roller bearings and spherical roller bearings.
According to its work, it can be divided into aligning bearings - the raceway is spherical, the angular deviation between the two raceway axis and the angular motion of the bearing and the non - adjustment bearing (rigid bearing) - the bearing that can impedance the axis angle deviation between the raceway.
According to the number of rollers, it can be divided into single row bearings, double row bearings and multi row bearings.
It can be divided into separable bearings and non separable bearings according to whether their components (rings) can be separated.
According to its structure and shape (if there are no filling grooves, the shape of inner, outer ring and ring, the structure of the block, even without the cage) can be divided into many kinds of structure types.
According to its outer diameter, it is divided into micro bearing (<26mm), small bearing (28-55mm), medium and small bearing (60-115), medium and large bearing (120-190mm), large bearing (200-430mm) and super large bearing (>440mm).
It is divided into motor bearing, rolling mill bearing, main bearing and so on.
According to the material, it is divided into ceramic bearing, plastic bearing and so on.
