SKF 7211-ACD/P4AQGB super-precision angular contact ball bearings, supplied as a matched set of four. Series: 72, medium section. Bore: 55 mm. Outside Diameter: 100 mm. Width: 21 mm per bearing. Open on both faces, machined fabric-reinforced phenolic resin cage, steel balls on steel raceways. Searchable forms: 7211 ACD/P4AQGB, 7211ACDP4AQGB, 7211-ACD-P4A-QGB, 7211ACD/P4A QGB.
Contact Angle: 25°. Precision Class: P4A — ABEC 7 dimensional tolerance with running accuracy held to ABEC 9. Set size: four bearings. Preload: light. Universally matchable grinding. Cage: machined phenolic resin, rated for continuous service to 120°C.
A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope. Four rows in one bearing position give high axial and radial capacity and high stiffness for a heavily loaded spindle. Per bearing: Dynamic Load Rating 47.5 kN, Static Load Rating 36.5 kN. Light preload balances shaft location stiffness against heat generation at speed.
Four bearings. Unit Quantity: 4 Pcs. Universally matchable: the rings are ground so any two bearings clamped face to face or back to back reach the specified light preload, which allows the four to be built into back-to-back, face-to-face and tandem combinations. Open bearings, lubricated on installation with oil or grease.
All four bearings are clamped against a common shoulder and locknut for the ground preload to take effect. The phenolic cage sets the temperature ceiling at 120°C. Preloaded bearings run without internal clearance, so shaft and housing seats are held to super-precision tolerances.
FAG B7211-E-T-P4S-QUM is a universally matched quadruplex set at 25° and medium preload. SKF 7211 ACD/P4AQGA is the same set at extra light preload, and SKF 7211 CD/P4AQGB is the same size at 15°.
