Decoding SKF 3314 A-2Z/C3
- 33Series
- Double row angular contact ball bearings, 33 series. Series differ in outside diameter and width even when the bore is the same.
- 14Bore
- Bore 70 mm (14 × 5).
- A-2Z/C3Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
3314 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 3314 A-2Z/C3 measures 70 mm across the bore and 150 mm across the outside diameter; its width is 63.5 mm (70 x 150 x 63.5 mm).

Double row angular contact ball bearings in the SKF A-2Z/C3 series handle combined radial and axial loads in both directions. Each bearing carries two metal shields and C3 internal clearance. MR Industrial Accessories supplies this line to maintenance departments and OEMs across the United States and Latin America.
Reading the code helps you order the right variant. The basic number, such as 3208, 3212, 3313 or 3314, sets the size and dimension series. The letter A denotes an internal design variant. The 2Z suffix means two steel sheet shields, one per side, which keep dust out and hold lubricant in. C3 indicates radial internal clearance above normal, useful when thermal expansion is expected. So 3208 A-2Z/C3 is a double row bearing with metal shields and increased clearance.
These bearings fit centrifugal pumps, compressors, fans, machine tools, power transmission equipment and conveyor rollers. Because they take combined loads, they suit assemblies that need the shaft rigidly positioned, such as gearboxes and spindles. They also appear in food, chemical and petrochemical plants when the sealing matches the environment.
Selection starts with the radial and axial loads, then rotational speed and operating conditions. Choose C3 clearance when temperature differences between shaft and housing are likely or when the fit is tighter than normal. The 2Z shields block dust and dirt but are not liquid-tight; for humid areas or fluid exposure, look at variants with elastomer seals. During mounting, align shaft and housing and avoid impacts that could damage the raceways. The factory lubrication lasts for normal operating conditions without extra maintenance.
For interchangeability, bearings from other manufacturers with the same standardized designation can work if dimensions and internal clearance match. Catalogs may list equivalent codes, yet tolerances and heat treatment can differ. Check the technical specifications against your load and speed requirements before substituting. Our team can review the options with you.

Frequently asked questions
- SKF 3314 A-2Z/C3 bearing: what are its dimensions?
- SKF 3314 A-2Z/C3 measures 70 mm across the bore and 150 mm across the outside diameter; its width is 63.5 mm (70 x 150 x 63.5 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 3314.
- What does the C3 suffix mean on an SKF bearing?
- C3 means the bearing has radial internal clearance greater than normal. It compensates for thermal expansion and suits applications with higher operating temperatures or tighter mounting fits.
- Do 2Z shields protect against water?
- No. The 2Z shields are steel sheet and guard against dust and solid particles, but they are not liquid-tight. For water or fluid exposure, consider bearings with elastomer seals (2RS suffix).
- Can I replace an SKF bearing with another brand?
- Yes, if the replacement has the same dimensions, internal clearance and load capacity. Standardized designations help, but verify tolerances and sealing type. Contact us with the original code if you have doubts.
