Overview
Nachi NJ204 C3 Cylindrical roller bearing
Cylindrical Roller Bearing, single-direction locating design with increased clearance
With a 20 mm bore, 47 mm outside diameter and 14 mm width, the Nachi NJ204 C3 is a single-row cylindrical roller bearing that carries heavy radial load and takes axial thrust in one direction through the flange on its inner ring. C3 clearance is specified where the shaft runs hot relative to the housing or where the inner ring is mounted with a firm interference fit, either of which eats into the running clearance. Separable rings, pressed sheet steel cage.
Key features
- Locates the shaft axially in one direction
- Increased C3 clearance for thermal expansion
- High radial load capacity from line contact
- Separable rings simplify mounting
- Pressed sheet steel cage
- Suits interference fits on the inner ring
