The NJ 211 E TN C5 RICH Single Row Cylindrical Roller Bearing (55 mm ID, 100 mm OD, 21 mm width) features reinforced design (E), polyamide cage (TN), and C5 clearance for high heat applications.
The NJ 211 E TN C5 RICH is a robust Single Row Cylindrical Roller Bearing manufactured by RICH. Designed to handle exceptionally heavy radial loads and high-speed demands, this bearing has dimensions of 55 mm inner diameter, 100 mm outer diameter, and 21 mm width.
The NJ configuration means the outer ring has two integral flanges and the inner ring has one, allowing the bearing to accommodate axial displacement in one direction. The E suffix denotes a reinforced internal design, providing a maximized load carrying capacity. The TN suffix confirms the use of a high-strength polyamide cage, which contributes to lower friction, reduced noise, and increased speed capability.
Crucially, this model features a C5 internal clearance, which is significantly greater than the standard C3 and C4 clearances. This extra clearance is essential for applications involving very high operating temperatures or those requiring extremely heavy interference fits, where standard clearances would be insufficient. The combination of high capacity, thermal resistance, and separability makes the NJ 211 E TN C5 RICH ideal for the most demanding industrial environments such as high-performance gearboxes, large pumps, and steel mill equipment.
