FAG B71922E.T.P4S.K5.J15F.UL super precision angular contact ball bearing, also called a spindle bearing. Series B719, ISO 719 dimension series. Bore: 110 mm. Outside diameter: 150 mm. Width: 20 mm. Single row, open, straight bore. Searchable forms: B71922E.T.P4S.K5.J15F.UL, B71922ETP4SK5J15FUL, B71922-E-T-P4S-K5-UL-J15F, B-71922-ETP4SK5J15FUL, 7922.
Contact Angle: 25°. Cage Material: laminated fabric phenolic. Precision Class: P4S, FAG’s own class above P4. Preload: light. Arrangement: universal single bearing, adjusted for mounting in pairs or sets. Preload force in a light-preload pair: 455 N.
A 25° contact angle carries more thrust and gives higher axial rigidity than a 15° bearing on the same envelope, at a lower speed ceiling. Basic dynamic load rating, radial: 58 kN. Basic static load rating, radial: 44.5 kN. Fatigue load limit, radial: 4.15 kN. Limiting speed: 8,000 rpm on grease, 12,000 rpm on oil. Axial rigidity in light preload: 225 N/µm. P4S tolerances give closer running accuracy and lower vibration than P4.
One bearing. Universal design: two or more mount together back-to-back, face-to-face or in tandem, and a pair sets light preload without shims or measurement.
Diameter shaft shoulder: 117 mm. Shoulder diameter outer ring: 143 mm. Maximum recess radius: 0.6 mm. Minimum chamfer dimension: 1.1 mm. Distance between the apexes of the pressure cones: 40.3 mm. Operating temperature range: -30 °C to 100 °C. Weight: 0.85 kg.
Base designation: B71922E.T.P4S.UL. Equivalents at the same 25° contact angle and super precision class: SKF 71922 ACDGA/P4A, Fafnir 3MM9322WI, 71922ACDP4A. A B71922C on the same envelope carries a 15° contact angle and is a related size.
