SKF62132RS1C3Deep Groove Ball Bearing – 65 mm Bore, 120 mm OD, 23 mm Width, Contact Rubber Seals Both Faces, C3

Product Description

What this part is

SKF 6213-2RS1/C3 single-row deep groove ball bearing. Bore 65 mm, outside diameter 120 mm, width 23 mm. Straight bore, one row of balls, contact rubber seals on both faces, greater than normal C3 radial internal clearance, prefilled with grease.

Decoding the designation

6213 places the bearing in the 6200 medium dimension series at a 65 mm bore. 2RS1 denotes a contact seal on each face, so both sides are closed. C3 is the radial internal clearance class. The carton also carries GJN, SKF’s code for the grease charge, and JEM as a plant designation.

What these specs mean in practice

Contact seals rub against the inner ring land, which keeps water and fine dust out and grease in, at the cost of some running torque and a lower speed limit than a shielded or open bearing. C3 clearance runs looser than normal at rest, and that extra room is what absorbs the loss of clearance caused by an interference fit on the shaft and by a warm inner ring, so a C3 bearing keeps a working clearance in service where a CN bearing would go tight.

Published ratings

Radial dynamic load capacity 13,151 lbf (58.5 kN) and radial static load capacity 9,105 lbf (40.5 kN), at ABEC 1 precision. The cage is sheet steel and the seals are nitrile rubber.

Quantity and configuration

One bearing. Sealed on both faces and greased on assembly.

Fitting notes

Standard practice is an interference fit on the shaft and a location fit in the housing, with mounting force applied squarely to the ring being fitted. A sealed bearing needs no housing lubrication feed and no purge port. Heating for assembly is kept below the limit of the seal elastomer.

Interchange guidance

The 65 x 120 x 23 mm envelope is shared by every brand’s 6213, so a FAG 6213-2RSR-C3, NSK 6213DDUC3 or NTN 6213LLUC3 is a direct substitution. Closure and clearance both change the part within that envelope: a 6213-2Z/C3 has steel shields rather than contact seals, and a plain 6213-2RS1 is CN clearance, so both are related sizes.
