SKF deep groove ball bearings with the W64 suffix are single row bearings with a stainless steel cage and special treatment to resist corrosion. They are used in equipment where humidity, frequent washing or chemical agents can affect the service life of a conventional bearing. MR Accesorios Industriales carries this line as part of its SKF bearing offering.
The designation of these bearings follows the SKF system: the basic number indicates the type and dimension series. For example, in 6005/W64, the prefix 6 corresponds to the 60 series (extra light section), and the suffix /W64 indicates that the bearing incorporates a special corrosion-resistant execution. The same applies to 6204/W64 (62 series, light section) or 6405/W64 (64 series, medium section). The W64 suffix does not change the main dimensions, but it does change the surface treatment and the cage, which is usually stainless steel.
These bearings are used in the food, pharmaceutical and chemical industries and in processing equipment where cleaning with water or chemicals is common. They also appear in industrial washing machines, conveyors in humid environments, packaging equipment and irrigation systems. In Argentina, sectors such as food and chemical increasingly demand components that withstand frequent washing without premature degradation.
To select the right bearing, take into account the load, speed and environmental conditions. Sealing is key: if there is direct exposure to liquids, a bearing with contact seals (2RS suffix) or at least metal shields (2Z) is advisable. The lubricant must be compatible with the W64 treatment; in humid environments, a grease with high washout resistance is recommended. Correct alignment of the shaft and housing prevents additional loads that shorten service life.
Regarding equivalences, other manufacturers offer similar corrosion-resistant executions, but designations vary by brand. There is no universal nomenclature for the W64 suffix, so the technical specifications of the alternative manufacturer must always be verified. If you need to replace a bearing, the safest approach is to compare dimensions, sealing type, cage material and surface treatment before deciding.

Frequently Asked Questions
- What are the dimensions of the SKF 61910/W64 bearing?
- The SKF 61910/W64 bearing has a 50 mm bore, a 72 mm outside diameter and a 12 mm width (50 x 72 x 12 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 61910.
- What does the W64 suffix mean in an SKF bearing?
- The W64 suffix indicates a special corrosion-resistant execution, with a stainless steel cage and surface treatment that protects against humidity and chemical agents. It does not change the bearing dimensions, but it improves its durability in aggressive environments.
- Can I replace a W64 bearing with a standard one?
- It is not advisable if the equipment is exposed to humidity or chemicals, because the standard bearing will corrode prematurely. If the environment is dry and clean, a conventional bearing may be sufficient, but always verify the working conditions.
- How do I request a quote for SKF W64 bearings?
- Send the complete bearing part number via WhatsApp to MR Accesorios Industriales. If you do not have it, send us the main dimensions (inner diameter, outer diameter and width) and the working conditions so we can advise you.
