Inner and outer wall with cylindrical roller bearings
NJ -type cylindrical roller bsleeve bearing , the outer ring of the double wall , the inner wall of the single .
NF type cylindrical roller bearings, the outer ring of single-wall , double wall inner ring .
NJ type and NF -type cylindrical roller bearings , shaft or housing to limit the direction of the axial displacement to achieve a one-way axial positioning , and can withstand a small axial load .
NUP type cylindrical roller bearings, double outer wall , the inner wall on one side , the other side of the retaining ring . These bearings can be bi- axial positioning axes can withstand two-way axial force. Optional bearing structure type NUP ... N. There 's NJ HJ thrust collar type cylindrical roller bearings as NUP type cylindrical roller bearings , like , can be used as a locating bearing .
No inner or outer cylindrical roller bearings without
RNU type of bearings without inner ring , outer ring has a double wall , that is, without inner ring NU -type cylindrical roller bearings.
RN type , is no outer bearing inner ring has a double wall .
RNU -and RN -type cylindrical roller bearings , radial dimension for restricted parts , journal or directly as a shell hole surface raceway , raceway hardness, machining accuracy and surface quality should be lapped raceway similar.
