NJ405ECP Cylindrical Roller Bearing 25x80x21mm

Contact Us


Quantity:


Cylindrical roller bearings are essential components used in various industrial applications to support radial loads and high rotational speeds. It consists of an inner ring, an outer ring, cylindrical rollers, and a cage. The NJ Bearing Series have two fixed ribs on the outer ring and a fixed rib on the inner ring which can guide the shaft in a single direction (axially).The ECP design provides improved strength and heat resistance, making it suitable for higher operating temperatures and demanding applications. ECP bearings feature a lightweight, glass-fiber reinforced polyamide cage that provides excellent wear resistance, low friction, and reduced noise and vibration.
