Decoding SKF 3310 A-2Z
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 10Bore
- Bore 50 mm (10 × 5).
- A-2ZSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3310 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3310 A-2Z measures 50 mm across the bore and 110 mm across the outside diameter; its width is 44.4 mm (50 x 110 x 44.4 mm).

SKF double row angular contact bearings carry radial and axial loads in both directions thanks to their two ball rows. The design keeps the bearing compact and rigid, which suits precision applications where space is limited. MR Industrial Accessories LLC supplies this SKF line to customers in the United States and several Latin American countries.
Reading the SKF designation helps you order the right bearing. Take 3205 A-2Z: the 32 prefix identifies the double row series, 05 gives the bore diameter when multiplied by 5, A marks an internal variant, and 2Z means two protective sheet metal shields, one per side. A suffix such as 2RS instead points to rubber seals. Once you know these codes, identifying and ordering becomes straightforward.
Typical equipment includes electric motors, pumps, compressors, fans, machine tools and conveyors. Industries such as food, chemical, petrochemical and general manufacturing rely on them. Because the bearing accepts moderate axial forces in both directions, it also fits gearboxes and spindles. MR Industrial Accessories LLC supplies these bearings for replacement work and new projects.
Selection depends on radial and axial load, speed and the operating environment. Sealing matters: 2Z models block dust and particles, while 2RS models seal better against moisture and liquid contaminants. Correct lubrication and accurate alignment during mounting help extend service life. Avoid impacts and verify internal clearance for the application. If anything is unclear, our team can assist.
Double row bearings from other brands may carry similar designations, yet they are not always directly interchangeable. Internal clearance, preload and cage type can differ. Check critical dimensions and operating conditions before substituting one manufacturer's bearing for another. Our technical team can help you evaluate the options.

Frequently asked questions
- SKF 3310 A-2Z bearing: what are its dimensions?
- SKF 3310 A-2Z measures 50 mm across the bore and 110 mm across the outside diameter; its width is 44.4 mm (50 x 110 x 44.4 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3310.
- What does the 2Z suffix mean on an SKF bearing?
- It means the bearing has two protective sheet metal shields, one on each side. They keep out dust and particles but are not liquid-tight, so they suit moderately contaminated environments.
- Can I replace a double row bearing with a single row one?
- It is not recommended. Double row bearings handle axial loads in both directions and offer greater rigidity, which a single row bearing does not match. Consult a specialist before making a substitution.
- How do I choose between 2Z and 2RS sealing?
- Choose 2Z for dry dust or particles. Choose 2RS for moisture, splashes or liquid contaminants, since it has rubber seals. Keep in mind that rubber seals create more friction and may reduce the maximum speed.
