How to read SKF W 61900-2RS1/W64
- W 619Series
- Stainless steel deep groove ball bearings, W 619 series. For the same bore, each series has a different outside diameter and width.
- 00Bore
- 10 mm bore: code 00 stands for 10 mm by standard.
- 2RS1/W64Suffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
W 61900 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

SKF stainless steel deep groove ball bearings are components designed to withstand radial and axial loads in applications where corrosion is a constant threat. Their stainless steel construction makes them suitable for environments with humidity, frequent washdowns or exposure to mild chemical agents. MR Accesorios Industriales sells this line so you can replace conventional bearings in equipment that requires greater oxidation resistance, without sacrificing precision or rotation capability.
The designation of this series combines several indicators. The prefix W indicates that the bearing is made of stainless steel. The numbers that follow identify the size and the dimension series according to the code. The suffix 2RS1 indicates that it has rubber seals on both sides, which protects against the entry of contaminants. The extension /W64 refers to a variant with specific characteristics for applications that require greater corrosion resistance, such as use in the presence of water or cleaning agents.
These bearings are used in industries where hygiene and corrosion resistance are critical. In Argentina, they are common in food and beverage plants, where equipment is washed daily with water and detergents. They also appear in the pharmaceutical industry, in packaging and filling machines, and in chemical processing equipment. Other applications include pumps, fans, conveyors and water treatment machinery. Their ability to withstand moderate radial and axial loads makes them versatile in power transmission systems.
When selecting a stainless steel bearing, take sealing into account: the 2RS1 suffixes offer an effective barrier against moisture and particles, but if the equipment is submerged or receives direct jets, it is advisable to evaluate additional seals or a mounting with protection. Lubrication is also key: these bearings usually come with factory grease, but in corrosive environments a lubricant compatible with stainless steel and resistant to washdown may be necessary. Check shaft and housing alignment to avoid additional loads that reduce service life. Standard internal clearance is usually sufficient, but in applications with high temperatures greater clearance may be required.
As for equivalences, SKF stainless steel bearings can be interchanged with those of other brands that follow the same standardized dimensions. The W designation and the 2RS1 and /W64 suffixes are specific to SKF, but the main dimensions (bore, outer diameter and width) match those of other manufacturers that offer stainless steel bearings. If you need to replace an existing bearing, the safest approach is to compare the dimensions and the type of sealing. Not all stainless steel bearings have the same performance; always verify the permissible load and the limiting speed according to the manufacturer.
To choose the right bearing, gather the equipment data: type of load, rotation speed, environmental conditions and type of mounting. If you have doubts, the technical team at MR Accesorios Industriales can advise you. Send the complete bearing code or the shaft and housing dimensions via WhatsApp and we will quote you promptly.

Frequently Asked Questions
- What are the dimensions of the SKF W 61900-2RS1/W64 bearing?
- The SKF W 61900-2RS1/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 /W64 suffix mean on an SKF bearing?
- The /W64 suffix indicates a special variant of the bearing, generally associated with additional corrosion resistance characteristics or a specific surface treatment. It does not change the main dimensions, but it does affect behavior in aggressive environments. Ask us about the exact code to confirm the properties of your bearing.
- Can I replace a conventional bearing with a stainless steel one?
- Yes, as long as the dimensions and the type of sealing are compatible. Stainless steel bearings offer greater corrosion resistance, but they may have lower load capacity and limiting speed. Evaluate the conditions of your application and ask us to choose the best option.
- How do I know if I need a bearing with 2RS1 seals?
- If the equipment operates in humid environments, with dust or exposed to splashes, 2RS1 seals are recommended because they retain lubrication and block contaminants. In clean and dry applications, an open bearing or one with metal shields may be sufficient. Analyze the working environment.
