Double row cylindrical roller bearing
Since the rollers of the cylindrical roller bearings make line contact with the raceways, these bearings can support heavy radial loads and are suitable for high speed operation. Assembly and disassembly are comparatively easy even if the inner or outer ring requires a shrink fit, as the bearing is a separation type.

Type NNU, NN : These bearings are used in the mainshaft of machine tools, rolling mill rolls and printing machine plate cylinders where thin walled bearings are needed. To use the bearing in the main shaft of machine tools, adjust the radial internal clearance by inserting a tapered inner ring to the tapered shaft.
