For rotating shafts, the SKF HSA radial shaft seal keeps lubricant where it belongs and keeps dust, water, and particles out. You will find it in gearboxes, pumps, electric motors, and other industrial equipment. MR Industrial Accessories supplies this SKF seal line and can help you match the right size to your application.
The part number itself tells you the dimensions and lip style. Take 5220X5340X25 HSA7C H: shaft 5220 mm, housing 5340 mm, width 25 mm, with an HSA7C lip and an H spring. HSA means a nitrile lip with a steel spring, so it handles oil and grease. The C and H suffixes show variations in the compound and whether a spring is present.
These seals show up in food processing, cement, steel, and oil operations, on gear reducers, centrifugal pumps, fans, and conveyors. They tolerate moderate peripheral speeds and low pressures, which makes them a practical choice for rotating shafts that see dust or moisture.
Selection comes down to three measurements: shaft diameter, housing bore, and available width. The lip needs a ground, lubricated surface to run on. Shaft and housing must align well, or the seal will wear early. A light coat of compatible grease on the lip before installation helps it seat. For high-speed operation, look at a design with better heat resistance.
SKF seals interchange with other European and American brands that use the same standard dimensions. When you replace one, compare dimensions and lip type. Suffixes are not universal, so check the full code. At MR Industrial Accessories, we can point you to equivalents and help you sort through the options.

- HSA indicates a seal with a nitrile lip and a steel spring, built to hold oil or grease on rotating shafts. The C suffix refers to the compound, and H shows the spring is present. It is an SKF internal designation for general-purpose industrial seals.
- How do I choose the right seal for my equipment?
- You need the shaft diameter, housing diameter, and width. Also factor in rotation speed and operating temperature. With those details, we can identify the matching SKF code. If you have the old seal, send us its dimensions or the engraved code.
- Are SKF seals compatible with other brands?
- Generally, SKF seals interchange with other brands that follow the same standard dimensions. However, suffixes can differ between manufacturers. Always verify dimensions and lip type before replacing. We can advise you on equivalents.
