FAGB7020ETPAT9ULAngular Contact Ball Bearing – 100 mm ID, 150 mm OD, 24 mm Width, Open, 25° Contact Angle, Universal Light Preload.

Product Description

What this part is

FAG B7020ETPAT9UL super precision angular contact ball bearing, also called a spindle bearing. Series B70, B70..-E design. Bore: 100 mm. Outside diameter: 150 mm. Width: 24 mm. Single row, open, straight bore. Searchable forms: B7020ETPAT9UL, B7020E.TPA.T9.UL, B-7020-E-TPA-T9-UL, B7020 E TPA T9 UL, 7020E.

Decoding the designation

Contact Angle: 25°. Cage Material: laminated fabric phenolic. Preload: light. Arrangement: universal single bearing, adjusted for mounting in pairs or sets. Preload force in a light-preload pair: 681 N.

What these specs mean in practice

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: 79 kN. Basic static load rating, radial: 55 kN. Fatigue load limit, radial: 5.2 kN. Limiting speed: 8,000 rpm on grease, 13,000 rpm on oil. Axial rigidity in light preload: 242 N/µm. A phenolic cage runs quietly at high speed and holds oil in its fabric structure.

Quantity and configuration

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.

Fitting notes

Diameter shaft shoulder: 110 mm. Shoulder diameter outer ring: 141 mm. Maximum recess radius: 1.5 mm on the shaft side, 0.6 mm on the housing side. Minimum chamfer dimension: 1.5 mm. Distance between the apexes of the pressure cones: 41.1 mm. Operating temperature range: -30 °C to 100 °C. Weight: 1.24 kg.

Interchange guidance

Base designation: B7020E.T.P4S.UL. Equivalents at the same 25° contact angle: SKF 7020 ACD/P4A, NSK 7020A5TYNSULP4, Fafnir 3MMV9120WI. A B7020C on the same envelope carries a 15° contact angle and is a related size.
