SKF W series stainless steel deep groove ball bearings are components designed to support radial and axial loads in both directions, with the particular feature of being manufactured in stainless steel, which makes them corrosion resistant. They are used in applications where humidity, frequent washdowns or chemical agents are present, such as medical equipment, the food industry or machinery exposed to the weather. MR Accesorios Industriales offers this line as part of its range of SKF bearings.
The W series designation is read as follows: the letter W indicates that the bearing is manufactured in stainless steel. The basic number (for example, 605, 606, 608) then corresponds to the size and section of the bearing according to the ISO standard. The suffixes that follow, such as -2RS1, indicate that the bearing includes rubber seals on both sides, which protects against the entry of contaminants and retains the lubricant. In the examples, W 608-2RS1 is a stainless steel bearing with seals on both sides, while W 619/6 X-2RS1 belongs to the thin-section 619 series, with the X suffix indicating modified dimensions. Knowing these codes allows you to quickly identify the characteristics of the product.
These bearings are used in industries where corrosion is a critical problem. In Argentina, they are found in food and beverage processing equipment, where washing with water and chemical products is frequent; in the pharmaceutical and medical industry, for instruments and equipment that require strict hygiene; in vending machines and refrigeration equipment; in marine or coastal applications; and in agricultural machinery exposed to the weather. They are also common in pumps, fans and conveyor systems that operate in wet environments. Their corrosion resistance extends service life and reduces maintenance.
To correctly select a bearing from the W series, take into account the type of load (radial, axial or combined), the rotation speed and the environmental conditions. Check that the -2RS1 sealing is suitable for the level of contamination; if there is exposure to liquids, the rubber seals are essential. Factory lubrication is usually sufficient for most applications, but in cases of high temperatures or high speeds a special grease may be required. During mounting, ensure correct alignment between shaft and housing, and avoid striking the bearing so as not to damage the seals or the raceways. Careful mounting guarantees the expected performance.
As for equivalences and interchangeability, SKF W series bearings follow standardized ISO dimensions, so they can be interchanged with stainless steel bearings from other brands that share the same basic designation and suffixes. However, it is important to verify that the material and the type of sealing match the requirements of the application. Not all manufacturers offer the same quality of stainless steel or the same seal design, so substitution must be done with caution. If you have any doubts, consult our technical team to ensure compatibility.

Frequently Asked Questions
- What are the dimensions of the SKF W 619/8-2RS1 bearing?
- The SKF W 619/8-2RS1 bearing has a 8 mm bore, a 19 mm outside diameter and a 6 mm width (8 x 19 x 6 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation W 619/8.
- What does the -2RS1 suffix mean on a SKF W series bearing?
- The -2RS1 suffix indicates that the bearing has rubber seals on both sides. These seals protect against the entry of dust, water and other contaminants, and retain lubrication. They are ideal for applications in wet or dirty environments.
- How does a W bearing differ from a conventional one?
- The main difference is the material: W series bearings are manufactured in stainless steel, which gives them high corrosion resistance. Conventional bearings are usually made of chrome steel, which is more prone to rusting in wet or chemical environments.
- Can I replace a SKF W bearing with one from another brand?
- Yes, as long as the dimensions and the type of sealing match. SKF W series bearings follow ISO standards, so they are interchangeable with other stainless steel bearings that have the same basic designation. Always verify the quality of the material and the seals.
