Decoding SKF 3307 A-2RS1/C3
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 07Bore
- Bore 35 mm (07 × 5).
- A-2RS1/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3307 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3307 A-2RS1/C3 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 34.9 mm (35 x 80 x 34.9 mm).

SKF double row angular contact bearings carry radial and axial loads in both directions thanks to their two-row ball design. That construction suits machinery that needs high rigidity and precision, and it holds up in demanding industrial service.
Reading the part number tells you most of what you need. Take 3205 A-2RS1/C3: the 32 prefix marks the double row series, and the size code follows it. The A suffix reflects an optimized internal design. 2RS1 means rubber seals on both sides, which keep contamination out and lubricant in. C3 signals internal radial clearance above standard, which fits high-temperature operation or interference fits.
You will find these bearings in centrifugal pumps, compressors, industrial fans, machine tools and power transmission equipment. Because they handle combined loads, they work well where load direction changes or where support must be rigid. Mining equipment, cement plants and water treatment plants also rely on them.
Selection comes down to load magnitude and direction, operating speed and the surrounding environment. The 2RS1 seal handles dust and moisture well, while an open design may be the better choice when higher speed is needed. Choose C3 clearance when thermal gradients or tight fits are present. During assembly, keep alignment precise and lubrication adequate; a clean work area and the right tools prevent premature damage.
On interchangeability, SKF double row angular contact bearings can replace other brands that share the same dimensional designation. Tolerances, internal clearance and sealing can still differ and affect performance, so check the technical specifications before substituting a bearing. MR Industrial Accessories LLC supplies bearings from leading brands and can advise on the right option for your application.

Frequently asked questions
- SKF 3307 A-2RS1/C3 bearing: what are its dimensions?
- SKF 3307 A-2RS1/C3 measures 35 mm across the bore and 80 mm across the outside diameter; its width is 34.9 mm (35 x 80 x 34.9 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3307.
- What does the 2RS1 suffix mean on these bearings?
- It indicates rubber seals on both sides. These seals block contaminants and retain lubricant, which helps the bearing last longer in dirty or humid conditions.
- When should I use a bearing with C3 clearance?
- C3 clearance suits bearings running at elevated temperatures or mounted with interference fits that reduce internal clearance. It also helps where thermal expansion must be compensated.
- Can I replace an SKF bearing with one from another brand?
- Yes, provided the dimensions and tolerances are equivalent. Load, speed and sealing specifications can vary between manufacturers, so verify them first. Contact us and we will help confirm compatibility.
