Cylindrical roller bearings in premium-quality.
- For high radial load.
- Displaceable in both directions (type NU) or in one direction
(Type NJ).
- Usable for high speed, with groove and 3 lubribation holes.
- Easy to mount (the inner ring is loose).
Temperature range: -30°C to +90°C (for short time up to +110°C).
Features:
1 . Cylindrical roller bearing with brass cage and removable inner
ring suitable for high radial loads
2 . CN (normal) radial clearance for applications where thermal
expansion is not a factor
3 . Single row roller bearing for high radial loads with low
friction
4 . Removable inner ring in open bearing allows for lubrication in
place
5 . Brass cage evenly spaces rollers for reduced friction,
vibration, and noise
Appalication:
Railway vehicle axle, motor, electrical appliances, machinery
equipment, spindle, generators, grinding, extrusion machine, coal
forming machine, roller mill neck and slow down devices,
construction machinery
