Decoding SKF W 61801
- W 618Series
- Stainless steel deep groove ball bearings, W 618 series. Series differ in outside diameter and width even when the bore is the same.
- 01Bore
- Bore 12 mm: by standard, 01 designates 12 mm.
W 61801 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF W 61801 measures 12 mm across the bore and 21 mm across the outside diameter; its width is 5 mm (12 x 21 x 5 mm).

When moisture, washdowns or chemical exposure are part of the operating environment, a standard bearing may not last. The SKF W series deep groove ball bearing is built from stainless steel to handle radial and axial loads where corrosion resistance and cleanliness matter. MR Industrial Accessories supplies this line as part of its bearing catalog for maintenance and purchasing teams across the United States and Latin America.
The W prefix in the part number identifies a stainless steel deep groove ball bearing. The digits that follow correspond to the size or load capacity, and the dimensions may be metric or inch according to the standard. Suffixes can indicate shields (2Z), contact seals (2RS) or other internal features. To match a replacement, start with the shaft diameter, housing bore and width, then confirm the load and speed conditions.
These bearings are common in food processing lines, sanitary pumps, packaging machines, irrigation systems and equipment used in chemical or pharmaceutical production. They also appear in marine and water treatment applications. In each case, the stainless steel construction resists oxidation that would shorten the life of a conventional bearing.
Sealing choice affects performance in wet or dirty areas. Open bearings allow lubricant flow but no protection; 2Z shields block larger particles; 2RS seals keep out moisture and contaminants. Internal clearance also plays a role: too much can cause vibration, too little can raise operating temperature. During mounting, align shaft and housing carefully and use methods that do not damage the rings. Select a lubricant compatible with stainless steel and the surrounding environment.
Interchange with other brands is possible when the boundary dimensions follow the same standard. However, tolerances and materials can differ between manufacturers, so verify the exact equivalent before substituting. MR Industrial Accessories can help you compare options and confirm interchangeability for your application.

Frequently asked questions
- SKF W 61801 bearing: what are its dimensions?
- SKF W 61801 measures 12 mm across the bore and 21 mm across the outside diameter; its width is 5 mm (12 x 21 x 5 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation W 61801.
- What does the W series indicate in SKF bearings?
- The W stands for stainless steel deep groove ball bearings. The number that follows indicates the size or load capacity. These bearings are chosen for humid or chemically exposed environments.
- Where are stainless steel bearings typically used?
- They are found in food, chemical, pharmaceutical, marine and water treatment applications where moisture or chemicals would corrode standard bearings. Also in equipment that is washed frequently or requires high hygiene.
- How can I determine the correct bearing size?
- You need the shaft diameter, outer diameter and housing width. With those measurements and the original part number, we can identify the exact size. If the part number is not available, send the dimensions via WhatsApp and we will assist you.
