Cylindrical roller bearing is a rolling bearing which roller is cylindrical roller to the heart. Provide load capacity, the main radial load. Friction is very small between roller rings and raised edge, suitable for high speed rotating. According to the rings which have raised edge, can divide a NU, NJ, NUP, N, NF single row bearings, and NNU, NN double row bearings.The inner ring and outer is separable .

method of extending the bearing's lifetime:
1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
2. Don't allow strong impact, such as hammer striking, transfer roller pressure
3. Use the accurate installation tool, avoid to use cloth kind and short fibers
4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5. General inspection, such as the surrounding temperature, vibrate, noise inspection
6. Keep bearing cleaning from dirt, dust, pollutant, moisture.
7. Bearing should not be ultra cooled.
