NSK Cylindrical Roller Bearings, Single-Row N-Type, N210W ,D=50
|Basic Load Ratings
DESIGN, TYPES, AND FEATURES
Cylindrical roller bearings are classified into the following types depending on whether or not they have ribs on their rings:
Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings.
The NH type consists of NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars
The inner ring loose rib of the NUP type should be mounted so that the marked side is on the outside.
If a cage is nonstandard for a given bearing number the number of rollers may vary; in such a case, the load rating will differ from that listed in the bearing tables.
Many NN double-row bearings have tapered bores, and they are primarily used in the main spindles of machine tools. Cages are made of either molded polyphenylenesulfide (PPS) or machined brass.
