NJ211 J P6 - 243452 Claas, 5199095 New Holland, JD10055 John Deere [BBC-R Latvia] Cylindrical roller bearing
Designation:
NJ211 (DIN 5412-1).
Design:
The cylindrical roller bearing consists of two rings (internal and external) and rolling elements (cylindrically-shaped rollers), connected with a cage - separator.
Features:
- with one flanged inner ring
- two protection flanges on outer ring
Advantages and restrictions:
Due to the greater contact area of the roller relatively to the ball - roller bearings provide approximately two times greater static and dynamic loads. This is their main advantage. The main limitation of roller bearings is their inability to withstand axial loads. Since only the lateral surface of the roller is a working part, such bearings can withstand only radial loads.
