SKF CYLROLLERBEARING NJ 221 ECP/C3

SKF cylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in: - the number of roller rows (one, two or four) - the type of cage (with, without or special designs) - Bearings with cage can accommodate heavy radial loads, rapid accelerations and high speeds. - Full complement bearings (without cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds. - SKF high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage. - the configuration of the inner and outer ring flanges (position and number of guide flanges)
