Decoding SKF 3312 ANR/C3
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 12Bore
- Bore 60 mm (12 × 5).
- ANR/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3312 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3312 ANR/C3 measures 60 mm across the bore and 130 mm across the outside diameter; its width is 54 mm (60 x 130 x 54 mm).

For equipment that must carry combined radial and axial forces, SKF double row angular contact bearings are a common choice. The two rows of balls give the bearing a rigid, precise behavior, which suits machines running at moderate to high speed. You will find them in pumps, compressors and gearboxes, among other industrial drives. MR Industrial Accessories LLC supplies these bearings as part of its SKF line.
The part code carries the key selection information. Take 3308 ANR/C3: the leading digits identify the size and series, ANR points to a variant with particular sealing or internal clearance features, and C3 means radial clearance above the standard value. Reading those suffixes correctly is what ensures the bearing matches the shaft and housing fit of your machine. If a code is unclear, send it to our team and we will help you confirm it.
Typical duties include centrifugal pumps, screw compressors, gearboxes and machine tools. Because the bearing takes combined loads, it fits positions that demand rigidity and accuracy, such as milling spindles or transmission shafts. Food and chemical plants also use it where dependable operation matters.
Selection starts with the radial and axial loads, the running speed and the surrounding conditions. During mounting, use the correct tools so the raceways are not marked. Choose a lubricant that matches the seal type and the working temperature. Shaft-to-housing alignment has a direct effect on how long the bearing will serve. Our team can guide you through each of these points.
Interchange with other brands is possible when the dimensional designation is the same, but tolerances and internal clearance can differ from one maker to another. Before substituting a bearing from a different brand, check those details with our technical staff to keep the application running as intended.

Frequently asked questions
- SKF 3312 ANR/C3 bearing: what are its dimensions?
- SKF 3312 ANR/C3 measures 60 mm across the bore and 130 mm across the outside diameter; its width is 54 mm (60 x 130 x 54 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3312.
- What does the C3 suffix mean in these bearings?
- C3 indicates internal radial clearance greater than the standard value. It is used when temperature differences between shaft and housing, or mounting interference, must be taken into account.
- Are these bearings suitable for high speeds?
- Yes, SKF double row angular contact bearings are made to run at moderate and high speeds, depending on lubrication and mounting. Check the technical data for each application.
- Can I replace a bearing from another brand with an SKF one?
- Often yes, provided dimensions and tolerances are equivalent. It is wise to verify internal clearance and operating conditions. Our team can help you validate interchangeability.
