Description
Cylindrical Roller Bearing, floating design with increased clearance
Nachi's NU311 C3 is a single-row cylindrical roller bearing measuring 55 mm bore by 120 mm outside diameter by 29 mm width, supplied with C3 internal clearance. The flangeless inner ring separates from the roller and cage assembly, which both simplifies mounting on an interference fit and allows the shaft to move axially within the bearing as it grows. C3 clearance is the usual choice where that thermal growth is significant or where the inner ring is pressed hard onto the shaft. Sheet steel cage, high radial capacity, no axial location.
