Fafnir7215WSingle Row Angular Contact Ball Bearing – 75 mm Bore x 130 mm OD x 25 mm Width, Open, 7200 Light Series

Product Description

What this part is

Fafnir 7215W single-row angular contact ball bearing. Bore: 75 mm. Outside diameter: 130 mm. Width: 25 mm. Series: 7200, single row angular contact, light. Closure: open on both faces. Rolling elements: bearing steel balls in a steel cage.

Decoding the designation

Series: 7200 — single row angular contact, light duty. Bore Size: code 15, which is 75 mm. Design: W, the low-shoulder-outer-ring angular contact execution. Precision Class: ABEC 1 / P0 — the standard commercial tolerance grade in the Fafnir angular contact range. The carton also carries 215-K, the Fafnir Conrad deep groove number on the same 75 x 130 x 25 mm envelope.

What these specs mean in practice

Dynamic Load Rating: 76 kN. Static Load Rating: 65.5 kN. Limiting Speed: 4,800 rpm. The low shoulder on the outer ring is what lets an angular contact bearing take a full ball complement and carry combined radial and one-direction thrust in a single row. Operating range: -30 °C to 120 °C.

Quantity and configuration

Unit Quantity: 1 Pc. Single bearing, individually packaged, supplied open. Item weight: 2.50 lb.

Fitting notes

The thrust face is the high-shoulder side of the outer ring, so the bearing is installed with that face against the housing shoulder that takes the axial load.

Interchange guidance

SKF 7215 BE and MRC 7215B share the 75 x 130 x 25 mm envelope at a 40° contact angle, which makes them a related size rather than a substitution. Fafnir 7215WN is the same envelope in the counterbored-both-rings 40° execution. Fafnir 215K is the deep groove bearing on the same envelope.
