1. Cylindrical Roller Bearing decription:

Cylindrical roller bearing is a kind of separable bearings, convenient for its assembly and disassembly especially it has the advantages in a condition that the interference is required and assorted with inner ring, outer ring and housing. The bearings consist of the cage, the rollers and guided by two capped edges on a ring. It is a separable bearing,

The NU cylindrical roller bearing has double capped edges on outer ring and without capped edge on inner ring.
The N cylindrical roller bearing has double capped edges on inner ring and without capped edge on outer ring.
The NJ cylindrical roller bearing has double capped edge on outer ring and single capped edge on inner ring.

The NF cylindrical roller bearing with the single capped edge on outer ring & double capped edges on inner ring.

The RNU cylindrical roller bearing has an outer ring with double capped edges but does not come with inner ring. Such bearing is the NU cylindrical roller bearings without the inner ring

The RN cylindrical roller bearing has an inner ring with double capped edge but does not come with outer ring.

2.method of expand the life time of bearing

1. Don't allow strong impact, such as hammer striking, transfer roller pressure

2. Use the accurate installation tool, avoid to use cloth kind and short fibers

3. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer

4. General inspection, such as the surrounding temperature, vibrate, noise inspection

5. Keep bearing cleaning from dirt, dust, pollutant, moisture.

6. Bearing should not be ultra cooled.
