SaiFan Cylindrical Roller Bearing NU218 Details

1. Cylindrical Roller Bearing NU218 Specifications :

Material: Bearing steel, GCR15
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). 

2. Cylindrical Roller Bearing NU218 Features :

1. The roller and raceway for the line contact or offline contact, radial bearing capacity big, apply to under heavy load and impact load.

2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings.

3. The N type and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing.

4. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration.

5. The inner ring or outer ring separable, easy to install and disassemble.

This cylindrical roller bearing with a brass cage and removable inner ring is suitable for applications that support high radial loads. This roller bearing has a CN (normal) radial clearance for applications and operating conditions with normal shaft and housing tolerances where thermal expansion is not a factor. This is a single row roller bearing that supports high radial loads with low friction. A removable inner ring in the open bearing allows application of lubrication. The brass cage prevents the rollers from coming into contact with each other during use, reducing friction, vibration, and noise.

Cylindrical roller bearings are used in applications where high radial loads are present such as in conveyer belts, traction motors, railway car axle boxes, and oilfield mud pumps, among others.
