Decoding SKF W 6204-2RS1/VP311
- W 62Series
- Stainless steel deep groove ball bearings, W 62 series. Series differ in outside diameter and width even when the bore is the same.
- 04Bore
- Bore 20 mm (04 × 5).
- 2RS1/VP311Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
W 6204 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF W 6204-2RS1/VP311 measures 20 mm across the bore and 47 mm across the outside diameter; its width is 14 mm (20 x 47 x 14 mm).

For equipment that faces moisture, washdowns or chemical exposure, the SKF W series stainless deep groove ball bearing offers a corrosion-resistant solution. Its stainless steel rings and metal components, combined with double-sided rubber seals, help keep contaminants out and lubrication in. This makes it a practical choice for sanitary environments and outdoor applications where standard bearings may not hold up.
The part number tells you what you are getting. The W prefix means the ring and metal parts are stainless steel. The following number, such as 608, 6000 or 6001, gives the size and dimensional series per ISO. The 2RS1 suffix indicates rubber seals on both sides, and /VP311 specifies a special grease that may be food-grade or high-temperature resistant depending on the application. So a W 6002-2RS1/VP311 is a stainless bearing of the 60 series, size 02, with two seals and VP311 lubrication.
These bearings are common in food, pharmaceutical, chemical and marine industries. You will find them in food processing equipment, filling machines, conveyors, pumps, fans and marine applications. They handle frequent washing with water and cleaning agents, making them suitable for sanitary settings.
When selecting, consider the radial and axial loads and the rotation speed. The 2RS1 seal works well in humid or dusty conditions, but for higher speeds, look at non-contacting seals. The VP311 grease is pre-applied at the factory; in high-temperature or high-speed use, check compatibility. During installation, align the shaft and housing carefully and avoid striking the seals. Use the proper tools to prevent damage to the rings.
For cross-referencing, SKF W series bearings can be interchanged with other brands that meet the same ISO dimensions and stainless material specs. However, load capacities and speed limits can differ. Always verify tolerances and lubricant type. When replacing an existing bearing, compare the inner diameter, outer diameter and width.
