SKF W series stainless steel deep groove ball bearings are manufactured from stainless steel, which gives them high corrosion resistance. They are suitable for applications where moisture, chemicals or frequent washdowns are present. They are used in medical equipment, the food industry, precision instruments and machinery exposed to aggressive environments. Their single-row ball design supports moderate radial and axial loads.

The designation of these bearings follows a clear pattern. The initial letter W indicates that the bearing is made of stainless steel, which gives it corrosion resistance. Then comes the series number, which defines the size and load capacity; for example, W 608-2Z corresponds to the 608 series, with a thin section and reduced outer diameter. The -2Z suffix indicates that the bearing incorporates two metal protective shields, one on each side, which prevent the entry of contaminants and retain the lubricant. Other possible suffixes, such as -2RS, indicate elastomer seals for tighter sealing. The examples W 619/3-2Z and W 619/4-2Z show the 619 series with very small diameters, typical of precision instruments.

These bearings are used in industries where corrosion is a constant problem. In the food industry, they are used in conveyors, mixers and packaging equipment that are washed daily. In the medical sector, they appear in infusion pumps, centrifuges and diagnostic equipment. They are also found in machines for the chemical industry, in irrigation systems, in marine equipment and in laboratory applications. In Argentina, they are common in food processing plants and in the pharmaceutical industry, where hygiene and resistance to cleaning agents are critical.

To select the right bearing, take into account the type of load, the rotation speed and the environment. If there is direct exposure to liquids or dust, choose the variant with -2RS seals instead of the -2Z shields. The factory lubrication is sufficient for most applications; if you need to relubricate, check that the bearing has a lubrication groove. During mounting, ensure correct alignment between shaft and housing to avoid additional loads. Use suitable tools and avoid striking the rings. Excessive interference can damage the seals and reduce service life.

When looking for equivalents, bear in mind that each manufacturer has its own nomenclature. A stainless bearing from another brand may have a similar code, but they are not always interchangeable in terms of tolerances or load capacity. SKF's W series stands out for its high-quality stainless steel and its specific suffixes. If you need to replace a bearing, the safest approach is to compare the critical dimensions and the service conditions. At MR Accesorios Industriales we can advise you to find the best option.
