Decoding SKF W 61902-2RS1/W64
- W 619Series
- Stainless steel deep groove ball bearings, W 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.
- 2RS1/W64Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
W 61902 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF W 61902-2RS1/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).

When moisture, washdowns or mild chemicals are part of the daily routine, standard bearings can fail early. SKF stainless steel deep groove ball bearings are built to handle radial and axial loads in those conditions. MR Industrial Accessories LLC supplies this line to help you replace conventional bearings in equipment that needs better oxidation resistance, while keeping the same precision and rotation performance.
The bearing code packs a lot of information. A W at the start tells you the ring material is stainless steel. The digits that follow define the size and the dimension series. The 2RS1 suffix means rubber seals are fitted on both sides, keeping contaminants out. The /W64 extension points to a variant with extra features for more demanding corrosion resistance, such as when water or cleaning agents are present.
These bearings show up in plants where hygiene and corrosion resistance matter. Food and beverage operations that wash equipment daily with water and detergents rely on them. You also find them in pharmaceutical manufacturing, in packaging and filling machines, and in chemical processing equipment. Pumps, fans, conveyors and water treatment machinery are other common homes. Their capacity for moderate radial and axial loads makes them a flexible choice in power transmission systems.
Sealing is a key selection point. The 2RS1 seals provide a solid barrier against moisture and particles, but if the bearing will be submerged or hit by direct jets, consider extra seals or a protected mounting. Lubrication also matters: these bearings typically arrive with factory grease, yet in corrosive settings you may need a lubricant that works with stainless steel and stands up to washdown. Check shaft and housing alignment to avoid extra loads that cut service life. Standard internal clearance usually works, but higher temperatures may call for greater clearance.
For interchange, SKF stainless steel bearings can be swapped with other brands that follow the same standardized dimensions. The W designation and the 2RS1 and /W64 suffixes are specific to SKF, but the bore, outer diameter and width match those of other manufacturers offering stainless steel bearings. When replacing an existing bearing, compare dimensions and sealing type first. Not all stainless steel bearings perform the same, so always verify permissible load and limiting speed with the manufacturer.
To pick the right bearing, gather equipment details: load type, rotation speed, environmental conditions and mounting style. If you need help, the technical team at MR Industrial Accessories LLC can assist. Send the complete bearing code or the shaft and housing dimensions via WhatsApp or email, and we will quote you promptly and suggest equivalents if needed.

Frequently asked questions
- SKF W 61902-2RS1/W64 bearing: what are its dimensions?
- SKF W 61902-2RS1/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 W 61902.
- What does the /W64 suffix mean on an SKF bearing?
- The /W64 suffix indicates a special variant, generally linked to additional corrosion resistance or a specific surface treatment. It does not change the main dimensions, but it affects how the bearing behaves in aggressive environments. Ask us about the exact code to confirm the properties.
- Can I replace a conventional bearing with a stainless steel one?
- Yes, if the dimensions and sealing type are compatible. Stainless steel bearings resist corrosion better, but they may have lower load capacity and limiting speed. Evaluate your application conditions and let us help you choose.
- How do I know if I need a bearing with 2RS1 seals?
- If the equipment runs in humid areas, with dust or splashes, 2RS1 seals are recommended because they keep lubrication in and contaminants out. In clean, dry applications, an open bearing or one with metal shields may be enough. Analyze the working environment.
