NSK 7209AW single row angular contact ball bearing. Bore Diameter: 45 mm (1.7717 in). Outside Diameter: 85 mm (3.3465 in). Overall Width: 19 mm (0.7480 in). Contact Angle: 30°. Number Of Rows: 1. Rolling Elements: Ball. Cage Material: Pressed steel. Precision Class: ISO Normal.
72 — single row angular contact ball bearing, ISO dimension series 02.
09 — bore code, 09 x 5 = 45 mm.
A — 30° contact angle.
W — pressed steel cage.
Dynamic Load Rating: 43,500 N (9,779 lbf). Static Load Rating: 28,700 N (6,452 lbf). Limiting Speed: 6,700 rpm grease; 9,500 rpm oil. Item Weight: 0.411 kg (0.906 lb). Effective load centre a: 28.3 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 single row angular contact bearing takes thrust in one direction only. Two are mounted opposed, back-to-back or face-to-face, to locate a shaft in both directions.
Bore Type: Straight. Shaft abutment diameter da min: 52 mm. Housing abutment diameter Da max: 78 mm. Fillet radius ra max: 1 mm. Chamfer r min: 1.1 mm, r1 min: 0.6 mm. Effective load centre a: 28.3 mm.
Unit Quantity: 1 Pc. Single bearing.
Same 45 x 85 x 19 mm envelope at 30°: SKF 7209 BE, Koyo 7209B, NTN 7209B, FAG 7209-B. Each maker’s cage, internal design and published ratings differ. NSK’s own 7209A super-precision executions, 7209ATYNSU and 7209ATRSU in P5, P4, P4Y and P3, share the envelope and angle but carry different cages, classes, speeds and ratings.
Common spellings and search variants carried on this part: 7209A, 7209AW, 7209E, 7209ACD, 7209-A-W.
