Product Description

Product Description

The cylindrical roller and raceway are linear contact bearings. Large load capacity, mainly bearing radial loads. The friction between the rolling element and the collar edge is small, suitable for high-speed rotation.The raceway and rolling body of cylindrical roller bearings are geometrically shaped.

Cylindrical roller bearings are suitable for loaders, bulldozers, rollers, automobiles, transmission shafts, gear shafts, etc. Double row cylindrical roller bearings are suitable for machine tool spindles.

Bearing characteristics
1. The roller and raceway are in line contact or repaired line contact, with a large radial bearing capacity, suitable for bearing heavy loads and impact loads.
2. The friction coefficient is small, suitable for high speed, and the limiting speed is close to Deep Groove Ball Bearing.
3. The N-type and NU type can move axially and adapt to changes in the relative position of the shaft and casing caused by thermal expansion or installation errors. They can be used as free end supports.
4. The machining requirements for the shaft or seat hole are high, and the relative deviation of the outer ring axis after bearing installation should be strictly controlled to avoid contact stress concentration.
5. The inner or outer ring can be separated for easy installation and disassembly.
