NSK cylindrical roller bearing

According to whether the ring has ribs or not, NSK cylindrical roller bearings are divided into NU, NJ, NUP, N, NF and other single-row bearings, and NNU, NN double-row bearings. The bearing is a structure in which the inner ring and the outer ring can be separated. Cylindrical roller bearings without ribs on the inner or outer ring, the inner and outer rings can move relative to the axial direction, so they can be used as free end bearings. Cylindrical roller bearings with double ribs on one side of the inner ring and outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. Generally, a steel stamping cage or a copper alloy turning cage is used. However, there are also part of the use of polyamide forming cage.

1. NSK cylindrical roller bearing The roller and the raceway are in line contact or trimmed line contact, and the radial bearing capacity is large, which is suitable for bearing heavy loads and impact loads.
2.NSK cylindrical roller bearings have a small friction coefficient, suitable for high speed, and the limit speed is close to that of deep groove ball bearings.
3. NSK cylindrical roller bearings N-type and NU-type can move axially, can adapt to changes in the relative position of the shaft and the shell caused by thermal expansion or installation errors, and can be used as free end support.
4. NSK cylindrical roller bearings have higher processing requirements for the shaft or seat hole. After the bearing is installed, the relative deflection of the outer ring axis should be strictly controlled to avoid contact stress concentration.
5.NSK Cylindrical Roller Bearings Inner or outer ring can be separated for easy installation and disassembly.
