Decoding SKF 3305 A/C3
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 05Bore
- Bore 25 mm (05 × 5).
- A/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3305 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3305 A/C3 measures 25 mm across the bore and 62 mm across the outside diameter; its width is 25.4 mm (25 x 62 x 25.4 mm).

Double row angular contact bearings are built to carry radial and axial loads in both directions. With two rows of balls running on inclined raceways, they also handle tilting moments, which makes them a good fit where rigidity and precision matter. MR Industrial Accessories supplies SKF bearings to maintenance and purchasing teams across the United States and Latin America.
The part number tells you most of what you need. In 3205 A/C3, the 3205 is a double row bearing with a 25 mm bore. In 3206 A/C3, the same design takes a 30 mm bore. The A suffix marks an internal design variant, and C3 means internal radial clearance is greater than standard, which suits higher operating temperatures or interference fits. Reading these codes correctly is the first step in matching a bearing to the application.
You will find these bearings in centrifugal pumps, compressors, industrial fans, machine tools and transmission equipment, as well as in food, textile, paper and metallurgy operations. Because they take axial load in both directions, they work well on shafts where axial forces alternate. They also suit high-speed, high-precision positions such as grinding machine spindles.
Selection comes down to load size and direction, rotation speed and the environment. Sealing matters: where contaminants are present, choose a variant with seals or shields. Lubrication must match the temperature and speed, and the C3 clearance helps when thermal expansion occurs. During mounting, keep alignment precise and avoid impacts that can damage the raceways, since poor mounting shortens bearing life.
Equivalents exist between brands, but suffixes and tolerances can differ from one maker to another. When replacing a bearing, confirm the bore, outer diameter and width, and the type of load it will carry. Send us the original code or the dimensions and we will help you find the right option.

Frequently asked questions
- SKF 3305 A/C3 bearing: what are its dimensions?
- SKF 3305 A/C3 measures 25 mm across the bore and 62 mm across the outside diameter; its width is 25.4 mm (25 x 62 x 25.4 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3305.
- What does the C3 suffix mean on a bearing?
- C3 indicates internal radial clearance greater than standard. It is specified for elevated operating temperatures or interference fits, where it compensates for thermal expansion and keeps clearance from becoming too tight.
- How do I choose between a single row and a double row bearing?
- A double row bearing supports axial loads in both directions and handles tilting moments, so it suits applications needing greater rigidity. A single row bearing takes axial load in one direction only and is typically used in pairs. Consider the loads and the space available.
- How do I request a quote for SKF bearings?
- Send the part number or the main dimensions by WhatsApp or email. Our team will reply promptly with a quote and can suggest equivalents or help you select the right bearing.
