The SKF RSH/WT series deep groove ball bearing is a single row bearing with contact seals on both sides and a specific factory lubrication. It is used in equipment exposed to dust, moisture or splashes, and where you do not want to depend on frequent relubrication. It is a common solution in electric motors, pumps, fans and conveyors. At MR Accesorios Industriales we sell it as a brand and help you identify the exact part number you need.

The designation of these bearings combines the size with suffixes that define the sealing and lubrication. In the example 6003-2RSH/WT, the 6003 indicates the size within the 60 series, extra light section. The suffix 2RSH means it has two contact seals, one on each side, made of synthetic rubber. The suffix /WT identifies a grease with specific characteristics loaded at the factory. Other part numbers in the same category may vary in the numeric prefix or in the suffixes, but the logic remains: size number plus sealing and lubricant indicators.

These bearings appear in applications where the environment is neither clean nor dry. In Argentine industry they are found in low and medium power electric motors, centrifugal pumps, extraction fans, conveyor belts and machine tools. They are also used in food industry equipment, where the seal prevents the entry of residues and facilitates cleaning. With double-sided sealing, they retain the grease and block contaminants, which extends service life compared to an open bearing.

To select the correct bearing, take into account the shaft diameter, the housing and the working conditions. The RSH seal is a contact seal, so it offers better protection than a non-contact seal, although with somewhat more friction. The WT grease is dosed at the factory and does not require relubrication in most cases. During mounting, make sure to clean the shaft and housing, avoid blows to the seals and verify alignment. Poor alignment accelerates wear on the raceways and seals.

Regarding equivalents, sealed deep groove ball bearings are available from different brands with their own nomenclature. The same size may appear as 2RS, 2RSH, DDU or similar depending on the manufacturer, but they are not always interchangeable in terms of internal clearance, lubricant or tolerance. Therefore, if you are going to replace a bearing, the safest approach is to compare the complete part number and the service conditions. If you have doubts, send us the part number engraved on the bearing and we will advise you.
