NSK 7215AW single row angular contact ball bearings supplied as a back-to-back matched pair. Bore Diameter: 75 mm (2.9528 in). Outside Diameter: 130 mm (5.1181 in). Overall Width: 25 mm (0.9843 in) per bearing. Contact Angle: 30°. Number Of Rows: 1 per bearing. Rolling Elements: Ball. Cage Material: Pressed steel.
72 — single row angular contact ball bearing, ISO dimension series 02.
15 — bore code, 15 x 5 = 75 mm.
A — 30° contact angle.
W — pressed steel cage.
DB — back-to-back arrangement. Two bearings ground as a set and mounted with their outer ring back faces together.
Dynamic Load Rating: 83,500 N (18,772 lbf) per bearing. Static Load Rating: 64,500 N (14,500 lbf) per bearing. Limiting Speed: 4,300 rpm grease; 6,000 rpm oil. Item Weight: 1.19 kg (2.62 lb) per bearing. Effective load centre a: 42.1 mm.
A 30° contact angle sits at the high-thrust end of NSK’s standard angular contact range: more axial capacity and greater axial stiffness than a 15° bearing, at a lower speed ceiling.
A back-to-back pair spreads the two load lines apart, giving the arrangement a wide effective bearing span and high moment stiffness within one housing bore. That is what makes DB the usual choice where an overhung load or a short shaft has to be held square.
Bore Type: Straight. Shaft abutment diameter da min: 84 mm. Housing abutment diameter Da max: 121 mm. Fillet radius ra max: 1.5 mm. Chamfer r min: 1.5 mm, r1 min: 1 mm. Effective load centre a: 42.1 mm per bearing. Mounting Arrangement: Back-to-back (DB).
Unit Quantity: 2 Pcs. A matched pair, ground as a set for back-to-back mounting. Load ratings and weight above are per bearing.
NSK 7215AWDF is the face-to-face matched pair of the same bearing. NSK’s 7215A super-precision executions, 7215ATYNSU and 7215ATRSU in P4 and P5, share the size and 30° angle but carry different cages, classes, speeds and ratings. SKF 7215 BE, Koyo 7215B, NTN 7215B and FAG 7215-B are the same 75 x 130 x 25 mm size at 40°, not 30°.
Common spellings and search variants carried on this part: 7215A, 7215AW, 7215ACD, 7215E, 7215AWDB, 7215-A-W-DB.
