NSK 7224CTDULP4 super-precision angular contact ball bearings, supplied as a universally matchable duplex pair. Open, single row per bearing, 15° contact angle, machined phenolic cage, light preload, P4 precision. Unit Quantity: 2 Pcs.
7224 — 72 series, bore code 24 = 120 mm bore.
C — 15° contact angle.
T — machined phenolic cage.
DUL — duplex pair, universally ground, light preload.
P4 — ISO class 4, equal to ABEC 7.
Bore Diameter: 120 mm. Outside Diameter: 215 mm. Overall Width: 40 mm per bearing. Total Width: 80 mm for the pair. Contact Angle: 15°. Preload: Light. Precision Class: P4 / ABEC 7. Cage Material: Phenolic. Number of Rows: 1 per bearing. Closure Type: Open. Dynamic Load Rating (Cr): 250 kN per bearing. Static Load Rating (C0r): 192 kN per bearing. Permissible Axial Load: 132 kN. Effective Load Centre: 42.4 mm. Item Weight: 5.42 kg (11.95 lb) per bearing. Harmonization Code: 8482.10.50.
Shaft abutment diameter da: 132 mm minimum. Housing abutment diameters Da 203 mm and Db 208 mm maximum. Fillet radii ra 2 mm and rb 1 mm maximum. Chamfer dimensions r 2.1 mm and r1 1.1 mm minimum. Rings are universally ground, so the pair mounts back-to-back, face-to-face or in tandem. The set is preloaded, so no internal clearance class applies.
