Bearing Classification
May 06, 2022
Bearings are usually divided into two categories according to their purposes:
1.General bearing: It is divided according to structure or size.
2. Special bearing: It is divided according to the occasion where the bearing is used. The following will introduce several special bearings:
1.General bearing: It is divided according to structure or size.
2. Special bearing: It is divided according to the occasion where the bearing is used. The following will introduce several special bearings:
Rolling mills can be divided into two-roll mills, four-roll mills, six-roll mills, and 20-roll mills. Roll bearing refers to the bearing installed on the journals at both ends of the work roll and backup roll. The roller bearings have to bear a large radial rolling force, and the radial space for installing the roller bearings is limited. Therefore, the rollers use multi-row roller bearings to withstand large radial forces, and sometimes use angular contact ball bearings. Or thrust bearing to bear the axial force. Mainly use four-row tapered roller bearings, four-row cylindrical roller bearings and spherical roller bearings
Motors are widely used in various mechanical equipment, and the quality of the motor is related to the running smoothness of the bearings used to a certain extent. It requires bearings with low noise, economy and simple support structure, usually deep groove ball bearings.
The machine tool bearing is the main part of the machine tool, and its working performance directly affects the quality and production efficiency of the workpiece. Generally, deep groove ball bearings, angular contact ball bearings, tapered hole double row cylindrical roller bearings, tapered roller bearings, thrust ball bearings, thrust roller bearings and two-way thrust angular contact ball bearings are generally used.

CHG Bearing：Bearings for wind turbinesApr 16, 2024Blade bearings are used to connect blades with hubs in MW wind turbines, and they also can adjust the windward direction of blades to ensure electricity production with power rating and the safe work of wind turbines. Usually, single or double rows four-point contact ball slewing bearings are used as blade bearings, which have preload, special designed seals, anticorrosion surfaces,etc.

CHG Bearing:The lifespan of bearingsMar 28, 2024The bearing life refers to the number of revolutions or hours experienced by the bearing before the occurrence of pitting under a certain load. The life of rolling bearings is usually defined by the number of revolutions or the number of hours worked at a certain speed. During this lifespan, no initial fatigue damage (such as spalling or defects) should occur on any bearing ring or rolling element.

Assembly and disassembly of tapered roller bearingsMar 21, 2024Tapered roller bearings can be mounted directly on a tapered shaft or on a cylindrical shaft through an adapter sleeve or withdrawal sleeve. A tight fit is obtained by axially moving the inner ring. The tight fit of the inner ring can be effectively controlled by measuring the reduction in radial clearance caused by the expansion of the inner ring.

Four row tapered roller bearingsMar 14, 2024It usually consists of two double-row inner rings, a double-row outer ring and two single outer rings. There is an inner spacer ring between the two inner rings, and there are two middle spacer rings between the three outer rings. Such a design The bearing can adjust the clearance to adapt to different working conditions.
