The SKF stainless steel deep groove ball bearing is a single row bearing with stainless steel rings and balls, designed to operate in humid, corrosive environments or with frequent washdowns. It is used in equipment where carbon steel would rust, such as the food, pharmaceutical or chemical industry. Its rigid design supports moderate radial and axial loads in both directions. MR Accesorios Industriales supplies this SKF line; contact us for your size or part number.
The designation of these bearings follows the SKF system: the prefix W indicates that the ring and rolling elements are made of stainless steel. The basic number, for example 61900, defines the series and size. The suffixes indicate variants: -Z for one metal shield, -2Z for two metal shields, and /W64 for an execution with special lubrication or tolerance characteristics. In the examples W 61900-2Z/W64 and W 61900-Z/W64 you can see the combination of stainless material, 61900 series and sealing type. Knowing these codes helps you order the correct replacement.
These bearings are used in industries where corrosion shortens the service life of conventional bearings. In Argentina, they are found in food and beverage plants, industrial washdown areas, chemical processing equipment, pharmaceutical machines and packaging systems. Also in marine or coastal applications, where humidity and salinity attack carbon steel. They are common in conveyors, pumps, fans and mixers that are washed daily or work with products that generate corrosive vapors.
To select the right bearing, take into account the type of contaminant: -Z or -2Z shields protect against dust and splashes, but do not immerse the bearing in liquids. The lubrication must be compatible with the environment; in wet applications, water-resistant greases are recommended. During mounting, check the alignment of the shaft and the housing, and avoid striking the rings. Cleaning the seat and using the right tools extends service life. If the equipment is washed frequently, consider periodic relubrication.
Regarding equivalences, SKF stainless steel bearings can be interchanged with those of other brands that follow the same dimensional and sealing designation, such as the 61900, 6000 or 6200 series in stainless version. However, not all manufacturers offer exactly the same tolerances or lubricants. Always verify the complete part number and the service conditions before replacing. MR Accesorios Industriales can advise you on interchangeability without compromising equipment performance.

Frequently Asked Questions
- What are the dimensions of the SKF W 61900-2Z/W64 bearing?
- The SKF W 61900-2Z/W64 bearing has a 10 mm bore, a 22 mm outside diameter and a 6 mm width (10 x 22 x 6 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation W 61900.
- What does the -2Z suffix mean on an SKF bearing?
- The -2Z suffix indicates that the bearing has two metal shields, one on each side. These shields protect against dust and splashes, but they are not sealed against immersion. For environments with liquids, it is recommended to evaluate contact seals.
- Is this bearing suitable for frequent washdowns?
- Yes, its stainless steel resists corrosion better than carbon steel. But -Z shields are not sealed; if the bearing is exposed to direct jets or immersion, contact seals and suitable lubrication should be used.
- Can I replace an SKF stainless steel bearing with one from another brand?
- Yes, if the dimensions and sealing type match. Verify that the part number is equivalent, for example the same series and suffixes. Tolerances and lubricants may vary between manufacturers, so contact us before installing.
