SKF 7204 ACDGA/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: bearing steel balls in a machined phenolic cage.
Contact Angle: 25°, from the ACD design code. Precision Class: P4A — ISO dimensional class 4 with ABEC 7 running accuracy. Preload: extra light, from the GA code. Universally matchable, so any two or more pieces stack in any combination and reach the stated preload without shims.
Dynamic Load Rating: 14.5 kN. Static Load Rating: 8.1 kN. Limiting Speed: 36,000 rpm. A 25° contact angle carries substantially more thrust and gives higher axial stiffness than a 15° bearing of the same size, at the cost of some speed capability. Extra light preload keeps running friction and heat generation down while still removing all play from the spindle.
Unit Quantity: 1 Pc. Single universally matchable bearing, supplied open. Item weight: 0.23 lb.
Straight bore, mounted directly on the shaft seat. Faces are universally ground for flush abutment. Internal Clearance: N/A on a preloaded execution. Operating range: -30 °C to 120 °C.
FAG B7204-E-T-P4S matches on angle, cage material and class. Fafnir 3MM204WI is the equivalent 25° execution on the same 20 x 47 x 14 mm envelope. SKF 7204 CDGA/P4A shares the envelope at 15° and is a related size.
