Decoding SKF 22311 EK/VA405
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 11Bore
- Bore 55 mm (11 × 5).
- EK/VA405Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22311 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 22311 EK/VA405 measures 55 mm across the bore and 120 mm across the outside diameter; its width is 43 mm (55 x 120 x 43 mm).

The SKF EK/VA line covers self-aligning spherical roller bearings that carry two rows of rollers, use a tapered bore and include a VA suffix for special execution. They handle combined loads and tolerate angular misalignment, which suits industrial drives, process equipment and machinery exposed to vibration or shock.
Reading the designation helps you order the correct item. The basic series number, such as 222 or 223, defines the bearing type and its load capacity. The EK suffix tells you the bore is tapered at 1:12, so the bearing mounts either on a tapered shaft or with an adapter sleeve. The VA code plus a number, for instance VA751, VA759 or VA405, marks a variant with specific internal clearance, heat treatment or tolerances. A full example is 22212 EK/VA751: 222 series, tapered bore, VA751 execution.
Typical users work in cement, mining, steel, paper and materials handling. Conveyors, mills, crushers, industrial fans and continuous process lines are common homes for these bearings. Because they take radial and axial load in both directions and accept misalignment, they fit equipment where the shaft deflects or where mounting is not perfectly aligned.
Selection depends on load, speed and the surrounding environment. The tapered bore simplifies installation and lets you set internal clearance through axial advancement. Lubrication and sealing must keep grease in and contaminants out. Careful alignment of shaft and housing is still required, even though the bearing absorbs some angular misalignment. For mounting and axial fixing, follow the manufacturer's instructions.
SKF bearings in this series can be replaced with equivalents from other makers, but the dimensions and the VA variant details must be checked, since special executions are not offered by every brand. Use equivalence tables and confirm that the substitute meets your load, speed and internal clearance needs. Interchange is never automatic; validate each case.

Frequently asked questions
- SKF 22311 EK/VA405 bearing: what are its dimensions?
- SKF 22311 EK/VA405 measures 55 mm across the bore and 120 mm across the outside diameter; its width is 43 mm (55 x 120 x 43 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22311.
- What does the EK suffix mean on an SKF bearing?
- EK means the bore is tapered at 1:12. The bearing then mounts on a tapered shaft or with an adapter sleeve, and axial advancement is used to set internal clearance.
- How do VA751, VA759 and VA405 differ?
- Each VA number identifies a distinct SKF specification, covering items such as internal clearance, heat treatment or tolerances. Send us the complete part number and we will advise you.
- How is a bearing with a tapered bore mounted?
- It goes on a tapered shaft or an adapter sleeve. Axial advancement controls internal clearance, so follow the manufacturer's instructions and check clearance reduction with measuring instruments.
