Decoding SKF 6212-2RS1/C3W64
- 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/C3W64Suffix
- 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

A deep groove ball bearing like this SKF unit handles radial and axial loads at the same time, which is why it turns up in so many industrial machines. The single-row ball layout keeps friction low and speeds high, so upkeep stays simple. This page explains what the suffix codes on the 6212 series mean and how to match sealing and clearance to your equipment.
Take a code such as 6212-2RS1/C3W64. The 2RS1 portion tells you there is a rubber seal on each side. C3 points to radial internal clearance above the standard value, and W64 refers to a special lubrication or treatment characteristic. Other versions use RS for one seal, 2RS for two, and C2, C3 or C4 to signal different clearance classes. Reading the designation this way lets you order exactly the bearing your machine needs.
Typical installations include electric motors, pumps, fans, conveyors and machine tools. Plants in the food, textile, cement and automotive sectors rely on bearings of this type because they carry combined loads and run at high speed. MR Industrial Accessories supplies the SKF line to customers throughout the United States and in several Latin American countries.
Sealing is the first decision. Rubber seals such as 2RS1 block dust and moisture, which suits dirty or damp surroundings. Metal shields, marked 2Z or ZZ, are the better pick when higher speed matters more than contamination protection. Choose C3 clearance when thermal expansion or interference fits on the shaft or housing would otherwise close up the internal gap. Grease from the factory usually covers the service life, though critical applications deserve a check on lubricant compatibility.
Fitting matters as much as selection. Use the right tools, never strike the seals, and confirm the shaft and housing are properly aligned before the machine goes back into service. Cross-brand substitution is possible, but tolerances, clearance and seal type must line up first; similar codes do not always mean identical bearings.

Frequently asked questions
- SKF 6212-2RS1/C3W64 bearing: what are its dimensions?
- SKF 6212-2RS1/C3W64 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 2RS1 indicate in a code like 6212-2RS1/C3W64?
- It means the bearing carries rubber seals on both sides, which keeps dust, dirt and moisture away from the rolling elements. That makes it a practical choice where contamination would shorten service life.
- When should I pick a bearing with C3 clearance?
- C3 suits applications that run hot, because thermal expansion eats into internal clearance. It is also the usual choice when the shaft or housing fit is an interference type and could otherwise preload the bearing.
- Can another brand replace an SKF bearing with a similar code?
- Often it can, but check dimensions, tolerances and the sealing arrangement first, since equivalent codes are not always identical. Send the original part number and the MR team will help you compare options.
