Know It All: N and NN Super Precision Cylindrical Roller Bearings
Posted by Engineering BoreCode on
Super Precision Cylindrical Roller Bearings of series N10xx and N30xx are top of the line rolling bearings known for runout control, rigidity, and high load ratings. Top manufacturers include SKF, Schaeffler FAG, NSK, and NTN. The non-locating design makes these bearings ideal for float (expansion) positions and are usually paired with high contact angle axial thrust ball bearings like Schaeffler FAG’s double direction 2344 series or a pair of single row bearings in main spindles, threading machines, printing machines, and other machine tool.
