Double-row angular contact ball bearings

A double-row angular contact ball bearing puts two rows of balls on angled raceways inside one inner ring and one outer ring. It carries radial load, axial load in either direction and tilting moments, and it needs less room than a pair of single-row bearings mounted face-to-face. Size it by shaft and housing diameter, the kind of load, the speed and the internal clearance you need.

From size 04 up, multiply the last two digits by 5 to get the bore; 00 means a 10 mm bore and 02 means 15 mm, as in 3200 ATN9 or 5302S. The 32 and 33 series belong to SKF, while 52 and 53 are used by NSK and NTN: NSK offers 5210, 5211 and 5310, and NTN 5200S and 5303S. Suffixes describe sealing and design. 2RS1 (3200 A-2RS1TN9/C3) means contact seals on both sides and 2Z (3201 A-2ZTN9/C3) means metal shields; at NSK, ZZ (5210AZZ) is shields and DDU (5210ADDU) is seals. TN9 stands for a polyamide cage and C3 for internal clearance greater than normal.

Typical applications are gearboxes, pumps, compressors, fans and drives that need a stiff, well-centered shaft. They make sense when the thrust reverses, since one bearing takes it both ways. When the axial load only acts in one direction, a single-row angular contact bearing is the better fit.

We carry double-row angular contact ball bearings from SKF, NSK and NTN. Send the full part number stamped on the bearing by WhatsApp or email. If you don't have it, give us shaft diameter, outside diameter, width and seal type, and we will cross-reference between brands and quote it promptly.
