Product Information

MRC angular contact bearings with a PJ suffix have one heavy race shoulder on the outer ring, opposing one heavy race shoulder and on recessed race shoulder on the inner ring. Because of this construction, it is possible for this bearing to incorporate a greater number of balls than a deep groove nonfilling notch bearing. The combination of maximum ball complement, optimum race groove depth, and the 40° contact angle results in high thrust load carrying capacity. 7000-PJ bearings are particularly suitable for positions where the thrust is always present in one direction. It should not be used where the bearing is subjected to radial load only, or combined radial and thrust load where the radial load is predominant. When heavy thrust must be taken in both directions, and angular contact bearing may be mounted in a duplex arrangement with another angular contact bearing or with a 9000-UP split inner ring bearing. 7000-PJ bearings are available with either peressed brass or machined brass, ball centered cages. The low shoulder diameters on the nonthrust sides of inner and outer rings, combined with large clearances between the land diameters and the cage, allow for large quantities of oil to flow through the bearings. The increased oil flow reduces operating temperature and theoretically increases bearing life. ABEC Grade 3 bore tolerances reduce the range of interference fits between the shaft and bearing bore. These tighter tolerances result in closer control of preload and minimize the risk of thermal runaway. 7400-PJ and PJD Series bearings are similar to the 7200-PJ and 7300-PH Series but are heavier sectioned and are used for very heavy thrust loads or combined radial and thrust loads where thrust is predominant.
