Decoding SKF 22318 E
- 223Series
- Spherical roller bearings, 223 series. Series differ in outside diameter and width even when the bore is the same.
- 18Bore
- Bore 90 mm (18 × 5).
- ESuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22318 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 22318 E measures 90 mm across the bore and 190 mm across the outside diameter; its width is 64 mm (90 x 190 x 64 mm).

Spherical roller bearings in the SKF E series are self-aligning units built with two rows of rollers running on a spherical raceway in the outer ring. That geometry lets them carry heavy radial loads together with axial loads in either direction, and it absorbs angular misalignment between shaft and housing. They suit equipment where shaft deflection or mounting inaccuracy would otherwise be a problem.
Reading the designation is the fastest way to narrow down a replacement. The basic number, for example 22205, 22206 or 22208, sets the size and dimension series. The E suffix marks an optimized design with greater load capacity than earlier versions. A code such as 22205/20 E points to a variant with a special bore diameter. With those three elements identified, the bearing is easy to match.
These bearings show up in mining, cement, steel and material handling operations, as well as in conveyors, mills, crushers and road machinery, where loads are heavy and conditions are demanding. Their self-aligning behavior is an advantage on long shafts that flex under load, or in assemblies where housings cannot be aligned perfectly.
Selection comes down to the radial and axial load the position must carry, the rotational speed and the shaft diameter. The E suffix leaves the external dimensions unchanged but affects load capacity. At mounting, apply proper lubrication and verify internal clearance, since too tight a fit shortens service life. Initial alignment matters less than with other bearing types, though it is still worth checking to avoid added stress.
Designations are not always interchangeable between manufacturers. A bearing with the same basic number from a different brand may carry a different load capacity, so confirm the critical dimensions and operating conditions before substituting. MR Industrial Accessories LLC supplies SKF as a brand, and our team can point you to the right option when you send the code and the working conditions.

Frequently asked questions
- SKF 22318 E bearing: what are its dimensions?
- SKF 22318 E measures 90 mm across the bore and 190 mm across the outside diameter; its width is 64 mm (90 x 190 x 64 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22318.
- What does the E suffix indicate on an SKF bearing?
- It identifies an optimized design with higher radial and axial load capacity. External dimensions stay the same, but performance changes. The suffix appears across spherical roller bearings in the 222 series and others.
- How do I decide between a 22205 E and a 22205/20 E?
- The bore diameter separates them. The 22205 E uses a standard bore, while the 22205/20 E has a special bore of 20 mm. Confirm the shaft size before choosing.
- Which applications call for SKF E series spherical roller bearings?
- Equipment that combines heavy loads with misalignment, such as conveyor belts, mills, crushers and road machinery. The self-aligning design works well on flexible shafts and in demanding assemblies.
