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. 7200-PJ and PJD Series bearings are used for heavy one-directional thrust loads or combined radial and thrust loads where thrust is predominant.

Of all the bearings I have purchased in the last 45 years, these look to be top quality.

Great bearings, great price!
I am rebuilding an old Delta/Rockwell drill press and was having trouble finding the correct replacement bearings at a reasonable price from my usual go-to online dealers; from those that even had them available. Shipping times where reasonable. Competitively priced at time of purchase. Stock status was available, had to use contact link to make sure they were available to ship. Would be very nice if real-time in-stock status could be available while hunting down need parts, but in the long run it's not that big of deal. The stock status email back following the inquire was quick with a quoted price and purchase link.
