FAG B71920C.TPA.P4.UL super precision angular contact ball bearing, also called a spindle bearing. Series B719, ISO 719 dimension series. Bore: 100 mm. Outside diameter: 140 mm. Width: 20 mm. Single row, open, straight bore. Searchable forms: B71920C.TPA.P4.UL, B71920CTPAP4UL, B-71920-C-TPA-P4-UL, B71920 C TPA P4 UL.
Contact Angle: 15°. Cage Material: laminated fabric phenolic. Precision Class: P4, ABEC 7. Preload: light. Arrangement: universal single bearing, adjusted for mounting in pairs or sets. Preload force in a light-preload pair: 316 N.
A 15° contact angle favours speed and radial stiffness and carries less thrust than a 25° bearing on the same envelope. Basic dynamic load rating, radial: 60 kN. Basic static load rating, radial: 45 kN. Fatigue load limit, radial: 4.3 kN. Limiting speed: 9,500 rpm on grease, 14,000 rpm on oil. Axial rigidity in light preload: 94 N/µm. A phenolic cage runs quietly at high speed and holds oil in its fabric structure.
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: 107 mm. Shoulder diameter outer ring: 133 mm. Maximum recess radius: 0.6 mm. Minimum chamfer dimension: 1.1 mm. Distance between the apexes of the pressure cones: 26.2 mm. Operating temperature range: -30 °C to 100 °C. Weight: 0.78 kg.
Current Schaeffler designation for this bearing: B71920C.T.P4S.UL. Other makers’ 15°, P4 numbers in 100 x 140 x 20 mm: NSK 7920CTYNSULP4 (light preload), SKF 71920 CD/P4ADGB (light preload, matched pair) and Fafnir 2MM9320WI (check cage and preload). A B71920E on the same size carries a 25° contact angle and is a related part.
