SKF HMS series radial shaft seals are single-lip seals designed to retain lubricant and exclude contaminants on rotating shafts. They are used in gearboxes, pumps, electric motors and gear reducers, among other applications. MR Accesorios Industriales markets this line as an official brand and helps you identify the correct seal based on dimensions and type of service.

The designation of these seals combines nominal dimensions and the suffix that defines the lip type. For example, 4X12X6 HMS46 R indicates a seal with 4 mm inside diameter, 12 mm outside diameter and 6 mm width, with HMS46 lip and the R marking. The HMS suffix identifies the lip geometry, while the number that accompanies it can vary depending on the compound and design. In examples 5X16X6 HMS4 R and 10X30X7 HMS4 R, the HMS4 suffix is repeated, indicating the same lip family for different sizes.

These seals are used in equipment with continuous rotation where oil or grease must be retained. They are common in gear reducers, centrifugal pumps, electric motors, spindles and transmission boxes. In Argentine industry, they appear in production lines, pumping equipment, agricultural machinery and transport. Their function is to prevent leaks and protect bearings from dust and moisture, extending the service life of the assembly.

To select the correct seal, check the shaft diameter, the housing and the available width. The lip must run on a ground and lubricated surface. Alignment between shaft and housing is critical: excessive misalignment accelerates wear. If the equipment operates in very dirty conditions, consider a lip with a dust guard. Lubricating the lip before installation and using the right tool prevent damage to the seal.

SKF radial shaft seals are interchangeable with those from other brands if dimensions and lip type match. However, each manufacturer may have variations in compound and lip design.
