SKF5205AZC3Double Row Angular Contact Ball Bearing – 25 mm ID, 52 mm OD, 20.6 mm Width, Shielded, 30° contact angle, C3.

Product Description

What this part is

An SKF 5205 AZ/C3 double row angular contact ball bearing, new open box. Bore Diameter: 25 mm. Outside Diameter: 52 mm. Width: 20.6 mm (13/16 in). Contact Angle: 30°. Two rows of balls in a back-to-back (O) arrangement inside one-piece inner and outer rings, with a metal shield. The 5200 series is SKF’s US numbering; the base metric catalogue designation is 3205 A.

Decoding the designation

5205 — SKF/MRC US numbering for the ISO 3205 double row angular contact series, 25 mm bore, light (02) section.

A — standard internal design for this series, sheet metal cage.

Z — metal shield (non-contacting).

C3 — greater than normal axial internal clearance.

What these specs mean in practice

Basic Dynamic Load Rating (C): 22 kN. Basic Static Load Rating (C0): 15.3 kN. These are the published figures for the A design on this envelope; a shield does not change them. Speed ratings are not listed here, because SKF’s published 12 000 r/min figure is for the open 3205 A and a shielded execution does not necessarily reach it. Cage: sheet metal. Axial Internal Clearance: C3. Material: bearing steel. C3 is specified where the bearing runs hot, where the inner ring takes a heavy interference fit, or where extra clearance is needed to keep preload off the bearing at temperature.

Mounting data

Arrangement of contact angle: back-to-back (O). Carries high axial load in both directions plus radial load and tilting moment, in less axial space than a matched pair of single row bearings.

Quantity and configuration

Sold as a single bearing. Not a matched set — this is a one-piece double row unit.

Interchange guidance

Base design: SKF 3205 A. Common spellings: 5205 A Z C3, 5205AZ, 5205-AZ/C3, 3205AZ.
