- 03Bore
- Bore 17 mm: by standard, 03 designates 17 mm.
- 2RSH/WTSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
6003 is the standard ISO basic designation, which sets the bearing type, series and bore.

This SKF deep groove ball bearing in the RSH/WT version comes with contact seals on both sides and factory-filled WT grease. It suits equipment where dust, moisture or splashes are present and where relubrication is not part of the routine. Electric motors, pumps, fans and conveyors are common places to find it. MR Industrial Accessories supplies this bearing and helps you confirm the exact part number for your application.
Reading the code tells you what you are getting. Take 6003-2RSH/WT: the 6003 is the size in the 60 series, extra light section. The 2RSH means two contact seals, one per side, in synthetic rubber. The /WT identifies the grease charged at the factory. Other part numbers in this family change the numeric prefix or the suffixes, but the pattern holds: size number plus sealing and lubricant indicators.
You will see these bearings where the environment is not clean or dry. Low and medium power electric motors, centrifugal pumps, extraction fans, conveyor belts and machine tools are typical. Food processing equipment also uses them because the seal keeps residues out and makes cleaning easier. Double-sided sealing retains grease and blocks contaminants, which supports a longer service life than an open bearing.
Selection depends on shaft diameter, housing dimensions and operating conditions. The RSH seal is a contact type, so it protects better than a non-contact seal, with somewhat more friction. WT grease is pre-dosed and generally does not need relubrication. When mounting, clean the shaft and housing, avoid impacts on the seals and check alignment. Misalignment speeds up wear on raceways and seals.
Sealed deep groove ball bearings from other brands use their own nomenclature. The same size may be listed as 2RS, 2RSH, DDU or similar, and they are not always interchangeable in internal clearance, lubricant or tolerance. For a replacement, compare the complete part number and the service conditions. If in doubt, send us the number engraved on the bearing and we will advise you.

Frequently asked questions
- SKF 6003-2RSH/WT bearing: what are its dimensions?
- SKF 6003-2RSH/WT measures 17 mm across the bore and 35 mm across the outside diameter; its width is 10 mm (17 x 35 x 10 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 6003.
- What does the RSH suffix mean on an SKF bearing?
- RSH indicates a contact seal on both sides, made of synthetic rubber. It keeps grease in and helps block dust, water and particles, making it suitable for contaminated environments.
- Does the WT suffix indicate a special grease?
- Yes. WT identifies a grease with specific characteristics loaded at the factory. It is intended to last the bearing's service life under normal operating conditions.
- Can I replace a 2RS bearing with a 2RSH one?
- Not always. Both have double-sided sealing, but they may differ in contact type, seal material or lubrication. Compare the complete part number and contact us on WhatsApp to verify interchangeability.
