NSK 7216BG single-row angular contact ball bearing. Bore: 80 mm. Outside diameter: 140 mm. Width: 26 mm. Series: 7200, 72 dimension series. Contact angle: 40°. Precision Class: ISO Normal (ABEC 1 / P0). Internal Clearance: CN. Open on both faces, pressed steel cage. Country of origin as recorded on this listing: Japan.
7216 = 72 series, 80 mm bore. B = the 40° contact angle series. G = universal matching, so faces are flush ground and any two bearings from the range mount together as a matched set. Searchable forms: 7216BG, 7216-BG, 7216 B G, 7216B, 7216BW. The NSK B-series code is its own scheme and is separate from a FAG B70 spindle designation.
A 40° contact angle is the highest thrust capacity in the single-row angular contact range, carrying axial load in one direction with high stiffness. Speed capability is correspondingly lower than a 15° or 25° execution. Universal matching means two or three of these bearings can be set back-to-back, face-to-face or in tandem without shims or grinding. The pressed steel cage suits grease and oil-bath lubrication in general machinery service.
Basic dynamic load rating Cr: 88.5 kN (19,900 lbf). Basic static load rating C0r: 69.5 kN (15,620 lbf). Limiting speed: 2,800 rpm on grease and 4,000 rpm in an oil bath. Effective load centre a: 59.1 mm. Mass: 1.49 kg (3.28 lb).
One bearing ships. Axial load is carried in one direction, so a two-direction location uses a pair of these bearings set back-to-back or face-to-face.
Shaft abutment diameter da: 90 mm minimum. Housing abutment diameter Da: 130 mm maximum. Shaft and housing fillet radius ra: 2 mm maximum. Chamfer dimensions r 2 mm and r1 1 mm minimum. The bearing is clearance-set at CN rather than preloaded, so it takes standard interference fits for the shaft and housing.
Direct equivalents at the same 40° angle and envelope: SKF 7216 BE, FAG 7216-B-TVP, NTN 7216B, Koyo 7216B. Related size: 7216C shares the 80 x 140 x 26 mm envelope at a 15° contact angle, which trades thrust capacity for speed, so it is a different part rather than a substitution.
