NJ2228ECM Cylindrical Roller Bearing 140x250x68mm
Specifications
Details
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 inner and outer rings have raceways, and the cylindrical rollers are arranged between these raceways. The cage keeps the rollers evenly spaced and prevents them from coming into direct contact with each other. Cylindrical roller bearings can carry high radial loads due to their line contact between rollers and raceways. However, they have limited axial load-carrying capacity.
