Decoding SKF 6212-2RS1/HC5C3WT
- 62Series
- Deep groove ball bearings, 62 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- 2RS1/HC5C3WTSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6212 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description

Series 62 and 63 from SKF cover deep groove ball bearings in medium and heavy sections. They take radial and axial loads in either direction, and their compact build fits common rotating equipment such as motors, pumps, fans and gearboxes. The notes below cover how the designation is put together, where this execution suits the application, and what to check during installation.
Reading a designation like 6210-2RS1/HC5C3WT: the 62 block is the medium series, 10 sets the bore, 2RS1 means rubber seals on both sides, HC5 points to hybrid construction with ceramic balls, C3 is a radial clearance above normal, and WT is a heat-treated variant for elevated temperatures. The same pattern applies to 6211-2RS1/HC5C3WT and 6313-2RS1/HC5C3WT. Between the two, series 63 carries a heavier section than 62, so it handles more load.
Typical installations sit in food processing, chemical, petrochemical and power generation plants. Low and medium voltage motors, centrifugal pumps, screw compressors, industrial fans and conveyor belts are all candidates when heat or contamination is present. Sealing combined with ceramic balls keeps maintenance needs down in these tougher surroundings.
Selection comes down to radial and axial load, running speed and operating temperature. The 2RS1 seal keeps out dust and moisture but caps the top speed; in a clean environment where more speed is needed, an open or shielded version can be the better fit. C3 clearance helps where the shaft or housing grows with heat. Grease fill normally lasts the bearing's life, though severe duty can call for relubrication.
During mounting, keep shaft and housing aligned so no extra load is introduced, and use pullers or a press rather than striking the rings. Confirm fits and clean mating surfaces. When swapping a bearing, check dimensions and tolerances against the original. Cross-brand equivalents exist, but the part number and specifications should always be verified.

Frequently asked questions
- SKF 6212-2RS1/HC5C3WT bearing: what are its dimensions?
- SKF 6212-2RS1/HC5C3WT measures 60 mm across the bore and 110 mm across the outside diameter; its width is 22 mm (60 x 110 x 22 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6212.
- What does the HC5 suffix indicate on an SKF bearing?
- HC5 marks a hybrid bearing with ceramic balls. Compared with an all-steel bearing, this lowers weight, improves corrosion resistance and permits higher speeds or temperatures.
- When should a C3 radial clearance be chosen?
- C3 suits situations where shaft and housing run at different temperatures, or where interference fit will close up the internal clearance. It also gives more room for expansion.
- Do 2RS1 sealed bearings require relubrication?
- As a rule they are greased for life and need no maintenance. In extreme temperature or speed conditions, shielded or open variants that allow relubrication may be the better choice.
