SKF 7204 CDGA/P4A single-row super-precision angular contact ball bearing. Bore: 20 mm. Outside diameter: 47 mm. Width: 14 mm. Series: 72 (7204). Bore form: straight. Closure: open on both faces. Rolling elements: chrome steel balls in a machined non-metallic phenolic cage.
Contact Angle: 15°, from the CD design code. Precision Class: P4A. Preload: light, from the GA code. Universally matchable, so pieces stack in any combination and reach the stated preload range without shims.
Dynamic Load Rating: 11.9 kN. Static Load Rating: 5.85 kN. Limiting Speed: 38,000 rpm. A 15° contact angle gives the highest speed capability of the super-precision angular contact range and high radial stiffness, with thrust taken in one direction. Light preload holds the spindle rigid while keeping frictional heat low, which is what allows the high speed rating.
Unit Quantity: 1 Pc. Single universally matchable bearing, supplied open. Item weight: 0.24 lb.
Straight bore, mounted directly on the shaft seat. Faces are universally ground for flush abutment in back-to-back, face-to-face or tandem stacks. Internal Clearance: N/A on a preloaded execution.
FAG B7204-C-T-P4S-UL matches on angle, cage material and class. Fafnir 2MM204WI is the equivalent 15° execution on the same envelope. SKF 7204 ACDGA/P4A shares the 20 x 47 x 14 mm envelope at 25° and is a related size.
