Steel Full Complement Cylindrical Roller Bearings For Locomotives 50mm Bore
Cylindrical roller bearings are available in many designs, series and sizes, including single row bearings with a cage, High-capacity bearing, single and double row full complement bearings (without a cage). Bearings with a cage can accommodate heavy radial loads, fast accelerations and high speeds. Full complement bearings incorporated a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.
Model:NJ210E
Basic Dynamic Load Rating:340kN
Basic Static Load Rating:335kN
Material of Rings and Balls: Chrome steel,Carbon steel, Stainless steel
Cage Material: Brass,Steel,Nylon
Features of Cylindrical Roller Bearing
1. High radial load capacity,is suitable for heavy load and impact load.
2. Small friction, suitable for high speed,the limiting Speed is close to Deep Groove Ball Bearings
3. N,NU series can adapt to high temperature and allow error during installation.
4. inner ring and outer ring are separable,easy to install and take down
