Decoding SKF 61902/W64
- 619Series
- Deep groove ball bearings, 619 series. Series differ in outside diameter and width even when the bore is the same.
- 02Bore
- Bore 15 mm: by standard, 02 designates 15 mm.
- W64Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
61902 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 61902/W64 measures 15 mm across the bore and 28 mm across the outside diameter; its width is 7 mm (15 x 28 x 7 mm).

SKF deep groove ball bearings carrying the W64 suffix are single row units built with a stainless steel cage and a surface treatment intended to resist corrosion. They suit equipment exposed to moisture, regular washdowns or chemical contact, where a standard bearing would deteriorate quickly. MR Industrial Accessories supplies this SKF line.
Reading the designation helps you confirm what you are ordering. In 6005/W64, the 6 identifies the 60 series (extra light section) and /W64 signals the corrosion-resistant execution. The same logic applies to 6204/W64 (62 series, light section) and 6405/W64 (64 series, medium section). Main dimensions stay the same with W64; what changes is the surface treatment and the cage, typically stainless steel.
Typical applications include food, pharmaceutical and chemical plants, plus processing equipment cleaned with water or chemicals. They also show up in industrial washing machines, conveyors in damp areas, packaging lines and irrigation systems.
Selection depends on load, speed and the surrounding environment. Sealing matters: for direct liquid exposure, choose contact seals (2RS) or at least metal shields (2Z). The grease must be compatible with the W64 treatment, and in wet conditions a lubricant with high washout resistance is preferable. Proper shaft and housing alignment avoids extra loads that reduce service life.
Other manufacturers offer comparable corrosion-resistant versions, but designations differ by brand. Since W64 has no universal equivalent, always check the alternative's technical data. When replacing a bearing, compare dimensions, sealing type, cage material and surface treatment before deciding.

Frequently asked questions
- SKF 61902/W64 bearing: what are its dimensions?
- SKF 61902/W64 measures 15 mm across the bore and 28 mm across the outside diameter; its width is 7 mm (15 x 28 x 7 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 61902.
- What does the W64 suffix mean in an SKF bearing?
- The W64 suffix denotes a special corrosion-resistant execution, featuring a stainless steel cage and a surface treatment that protects against humidity and chemical agents. Bearing dimensions remain unchanged, but durability in aggressive environments is improved.
- Can I replace a W64 bearing with a standard one?
- It is not advisable if the equipment sees humidity or chemicals, because a standard bearing will corrode prematurely. In a dry, clean environment a conventional bearing may suffice, but always verify the working conditions.
- How do I request a quote for SKF W64 bearings?
- Send the complete bearing part number via WhatsApp or email to MR Industrial Accessories. If you do not have it, provide the main dimensions (inner diameter, outer diameter and width) and the working conditions so we can advise you.
