Decoding SKF W 61902-2RS1
- 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.
- 2RS1Suffix
- 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 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, washdown chemicals or outdoor exposure are part of the daily routine, standard chrome steel bearings tend to fail early. The SKF W series answers that problem by using stainless steel for the rings and balls, so the bearing keeps working in damp or chemically aggressive settings. These deep groove ball bearings carry radial and axial loads in both directions and are common in medical instruments, food processing lines and equipment installed outdoors. MR Industrial Accessories LLC supplies this line as part of its SKF bearing range.
Reading the designation helps you confirm what you are ordering. The letter W at the start signals stainless steel construction. What follows is the basic number, such as 605, 606 or 608, which fixes the size and section under ISO rules. Suffixes come last: -2RS1 means rubber seals are fitted on both sides. So W 608-2RS1 is a stainless steel bearing with two seals, while W 619/6 X-2RS1 sits in the thin-section 619 series, where the X marks modified dimensions. Decoding the code this way makes it easy to match a bearing to an application before you send the part number.
Corrosion drives the choice of these bearings in several sectors. Food and beverage plants use them where water and cleaning agents are applied regularly. Pharmaceutical and medical equipment calls for them when hygiene standards are strict. They also appear in vending and refrigeration units, in pumps, fans and conveyors running in wet conditions, in coastal or marine settings, and in farm machinery left out in the weather. Stainless steel construction helps the bearing last longer in these environments and cuts the frequency of replacement work.
Selection comes down to three things: the load (radial, axial or a combination), the operating speed and the surrounding conditions. Check whether -2RS1 sealing matches the contamination level; where liquids are present, the rubber seals are not optional. The grease installed at the factory covers most applications, though high temperatures or high speeds may call for a different lubricant. During mounting, keep the shaft and housing aligned and avoid impacts, which can harm the seals or the raceways. Careful installation is what delivers the expected service life.
Because the W series follows ISO dimensions, bearings from other makers with the same basic number and suffixes can serve as substitutes. The catch is material and seal design, which are not identical across suppliers, so any swap should be checked against the demands of the application.

Frequently asked questions
- SKF W 61902-2RS1 bearing: what are its dimensions?
- SKF W 61902-2RS1 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 -2RS1 indicate on a SKF W series bearing?
- It shows that rubber seals are fitted on both sides. They keep dust, water and other contaminants out of the bearing and hold the lubricant in place, which suits wet or dirty operating conditions.
- How is a W series bearing different from a standard one?
- The material. W series bearings are built in stainless steel, giving them corrosion resistance. Standard bearings normally use chrome steel, which rusts more readily when exposed to moisture or chemicals.
- Can another brand replace a SKF W bearing?
- Often yes, provided the dimensions and sealing type line up. The W series follows ISO dimensions, so stainless steel bearings with the same basic designation can interchange. Confirm the material grade and seal design before substituting.
