Overview
Nachi NU317 C3 Cylindrical roller bearing
Cylindrical Roller Bearing, floating design with increased clearance
Nachi's NU317 C3 is a single-row cylindrical roller bearing measuring 85 mm bore by 180 mm outside diameter by 41 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.
Key features
- Increased C3 clearance for thermal expansion
- Floating design accommodates shaft expansion
- High radial load capacity from line contact
- Separable rings simplify mounting
- Pressed sheet steel cage
- Suits interference fits on the inner ring
