High Quality Oilfield Bearings NJ426EM Cylindrical Roller Bearing
Cylindrical Roller Bearing Description of Oilfield Bearings
Cylindrical roller and raceway for line contact bearings. Large load capacity, mainly bearing radial load. The friction between the rolling body and the rim of the ring is small, suitable for high-speed rotation. According to whether the ring has a rim or not, 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 detachable structure with inner ring and outer ring.
Features of Cylindrical Roller Bearing
1. Roller and raceway are in line contact or downline contact, radial bearing capacity is large, suitable for bearing heavy load
and impact load.
2. Small friction coefficient, suitable for high speed, limit speed close to deep groove ball bearings.
3. N type and NU type can be moved in axial direction, can adapt to the change of the relative position between the shaft and the
shell caused by thermal expansion or installation error, can be used as free end support.
4. The processing requirements for shafts or seat holes are high. After bearing installation, the relative deviation of the outer
ring axis should be strictly controlled to avoid contact stress concentration.
5. The inner ring or outer ring can be separated, easy to install and disas
