Decoding SKF 22215 EK/W64
- 222Series
- Spherical roller bearings, 222 series. Series differ in outside diameter and width even when the bore is the same.
- 15Bore
- Bore 75 mm (15 × 5).
- EK/W64Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
22215 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 22215 EK/W64 measures 75 mm across the bore and 130 mm across the outside diameter; its width is 31 mm (75 x 130 x 31 mm).

SKF spherical roller bearings handle radial and axial loads in both directions and tolerate shaft misalignment. The 22215 EK/W64, 22216 EK/W64, 22218 EK/W64 and 22220 EK/W64 are part of this self-aligning line. They suit equipment where deflection or mounting errors occur, such as conveyors, mills, pumps and gearboxes.
The code breaks down into sections. The basic number gives the size and width series, while suffixes define features. In 22215 EK/W64, 22216 EK/W64, 22218 EK/W64 and 22220 EK/W64, the numeric part sets the bore diameter and width series. The E denotes an optimized design with higher load capacity. The K means a tapered bore with a 1:12 taper. W64 indicates a variant with special treatment for greater corrosion resistance or moderate temperatures.
These bearings appear in continuous-process industries where reliability matters: cement, mining, steel, paper, food and aggregate processing. They are found in belt conveyors, vibrating screens, ball mills, high-flow centrifugal pumps, industrial fans and gearboxes. Self-alignment helps with long shafts that deflect or assemblies where supports cannot be perfectly aligned. Mobile public works equipment and the oilseed industry also use them.
Selection depends on radial and axial load, speed and environmental conditions. A K suffix means a tapered bore that needs a suitable adapter sleeve; check the taper and mounting method. In dusty, moist or particle-laden environments, consider variants with extra seals or protection. Use the lubricant recommended by the manufacturer, with quantity and frequency set by operating conditions. Initial alignment and internal clearance affect service life, so follow mounting instructions to avoid parasitic loads.
For interchangeability, SKF spherical roller bearings can be replaced by other brands that follow the same standardized dimensions and suffix designations. However, load capacities and surface treatments may differ. When evaluating a replacement, compare the basic number and all suffixes: an E may indicate a reinforced design not present in other brands. Ask us to help validate interchangeability for your application.
If you have your bearing code, send it by WhatsApp or email to MR Industrial Accessories and we will quote promptly. We can also suggest equivalents and help you choose if you need a variant with sealing, cylindrical bore or special treatment. We supply SKF bearings and other power transmission components.

Frequently asked questions
- SKF 22215 EK/W64 bearing: what are its dimensions?
- SKF 22215 EK/W64 measures 75 mm across the bore and 130 mm across the outside diameter; its width is 31 mm (75 x 130 x 31 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 22215.
- What does the EK suffix mean on an SKF bearing?
- The E indicates an optimized design with higher load capacity. The K means the bore is tapered with a 1:12 taper, allowing mounting with an adapter sleeve. Both suffixes matter for matching your shaft and mounting method.
- When should a spherical roller bearing be used?
- Use it when the shaft may become misaligned from deflection or mounting errors, or when radial and axial loads combine and vary. They suit heavy equipment such as conveyors, mills and gearboxes, where self-alignment helps extend service life.
- How do I request a quote for an SKF bearing at MR?
- Send the complete code by WhatsApp or email to MR Industrial Accessories. If you do not have it, provide the shaft and housing dimensions and the operating conditions. We will reply with the quote.
