The rolling elements are radial rolling bearings with cylindrical rollers. The internal structure of cylindrical roller bearings adopts rollers arranged perpendicularly to each other, which is also the origin of the name of crossed roller bearings. There are spacers or isolation blocks between the rollers to prevent the rollers from tilting or the rollers from rubbing against each other. , effectively preventing the increase in rotational torque
Product Features
The cylindrical rollers are in line contact with the raceway and have large radial load capacity. It is suitable for withstanding heavy loads and impact loads, as well as high-speed rotation.
The raceways and rolling elements of cylindrical roller bearings are geometrically shaped. After the improved design, it has a higher load-bearing capacity. The new structural design of the rib and roller end face not only improves the axial load-bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the roller end face and the rib, improving the Bearing performance.
Features
The rollers and raceways are in line contact or trimmed line contact. They have large radial load-bearing capacity and are suitable for bearing heavy loads and impact loads.
The friction coefficient is small, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
The type and type can move axially and can adapt to changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors. It can be used as a free end support.
The processing requirements for the shaft or seat hole are relatively high. After the bearing is installed, the relative deflection of the outer ring axis must be strictly controlled to avoid contact stress concentration.
The inner or outer ring can be separated for easy installation and disassembly
