Decoding SKF 6301-2RSH/W64
- 63Series
- Deep groove ball bearings, 63 series. Series differ in outside diameter and width even when the bore is the same.
- 01Bore
- Bore 12 mm: by standard, 01 designates 12 mm.
- 2RSH/W64Suffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6301 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF 6301-2RSH/W64 measures 12 mm across the bore and 37 mm across the outside diameter; its width is 12 mm (12 x 37 x 12 mm).

For equipment exposed to moisture, washdown or dust, SKF deep groove ball bearings with the 2RSH/W64 suffix combination are a practical choice. They carry radial and axial loads in both directions, come sealed on both sides and are pre-lubricated with a grease intended for wet conditions. Typical installations include electric motors, pumps and fans. MR Industrial Accessories supplies these bearings to customers across the United States and in several Latin American countries.
Reading the code helps you confirm what you are ordering. In 6003-2RSH/W64, the 6003 is the medium section series, 2RSH identifies nitrile contact seals on both sides, and W64 points to the special grease for wet service. The same logic applies to 6204-2RSH/W64 in the 62 series and 6301-2RSH/W64 in the heavier 63 series. Once you know the suffixes, you can tell at a glance how the bearing is sealed and lubricated.
These bearings fit electric motors, centrifugal pumps, fans, compressors and power transmission equipment. Because both sides are sealed, they handle dusty, damp or frequently washed areas such as food plants, wash bays and outdoor machinery. Conveyors and agricultural equipment also use them. In many cases they can replace similar bearings already in service, provided the dimensions and tolerances match.
Selection comes down to the radial and axial load, the rotation speed and the working environment. The 2RSH seal keeps contaminants out, though it can add some torque; at very high speeds, review other sealing options. W64 grease is made to resist washdown and humidity, so it suits applications where liquids are present. During mounting, align the shaft and housing correctly and do not strike the seals. No extra lubricant is required because the bearing arrives greased from the factory.
Interchange is possible with other brands that follow the same standardized dimensions. Suffix codes differ, however: some makers use 2RS or 2RS1 for contact seals, and each has its own designation for special greases. Confirm that bore, outer diameter and width match, and that the sealing and lubrication conditions are equivalent. If you are unsure, send us the original code and we will help you compare.

Frequently asked questions
- SKF 6301-2RSH/W64 bearing: what are its dimensions?
- SKF 6301-2RSH/W64 measures 12 mm across the bore and 37 mm across the outside diameter; its width is 12 mm (12 x 37 x 12 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6301.
- What does the 2RSH suffix mean on these bearings?
- The 2RSH suffix indicates nitrile contact seals on both sides. These seals retain the grease and block contaminants such as dust and moisture, which helps extend service life in demanding environments.
- Is W64 grease suitable for frequent washdowns?
- Yes, W64 grease is formulated to resist water washdown and moisture exposure. It is intended for equipment that is pressure-washed or operates in humid conditions, since it maintains its lubricating properties there.
- Can I replace a 2RS bearing with a 2RSH one?
- Generally yes, as long as the dimensions are the same. The 2RSH suffix is specific to SKF, but other manufacturers use similar designations for contact seals. Verify that the replacement meets the same load and speed specifications.
