The cylindrical roller and the raceway are linear contact bearings. Large load capacity, mainly bear radial load. The friction between the rolling element and the rim of the ring is small, which is suitable for high-speed rotation. According to the flange of the ring, it can be divided into NU, NJ, NUP, N, NF and other single-row cylindrical roller bearings, and NNU, NN and other double-row cylindrical roller bearings. The bearing is a structure with separable inner ring and outer ring.

accuracy level:

Cylindrical roller bearings can be divided into PO,P6, P5,P4, P2 according to the accuracy level. The accuracy level is sorted from low to high.

Features:

1. Roller and raceway for line contact or repair line contact, radial bearing capacity is large, suitable for bearing heavy loads and impact loads.

2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.

3. N type and NU type can move axially, can adapt to the change of the relative position of the shaft and the housing caused by thermal expansion or installation error, and can be used as a free end support.

4. The processing requirements for the shaft or seat hole are higher, and the relative deviation of the outer ring axis after the bearing installation should be strictly controlled to avoid contact stress concentration.

5. The inner ring or outer ring can be separated for easy installation and disassembly.

Application:

Large and medium-sized motors, rolling stock, machine tool spindles, internal combustion engines, generators, gas turbines, reduction boxes, rolling mills, shakers and lifting and transportation machinery etc.
