SKF HMSA7P2 R radial shaft seals keep lubricant in and contaminants out where a shaft turns. They appear in bearing housings, motors, pumps, gear reducers and similar equipment. An elastomeric lip works with a metal case that provides stiffness. MR Industrial Accessories LLC supplies this line and assists with size selection and cross-referencing.
The code follows a simple pattern. Take 10X22X6 HMSA7P2 R: the shaft is 10 mm, the housing bore is 22 mm and the width is 6 mm. The HMSA7P2 block covers the lip category and material variants, and the closing R denotes a particular version. The same reading applies to 18X30X6, 50X72X7 and 70X90X7: shaft first, then outer diameter, then width. Those three figures are enough to find the seal in a catalog.
These seals serve food, chemical, petrochemical and general manufacturing plants. Centrifugal pumps, electric motors, speed reducers, mixers and conveyors are typical locations, as is any process equipment that must hold oil or grease in and keep dust, water or vapors away from bearings. The HMSA7P2 R series spans small to larger shaft diameters, which makes it practical for maintenance and replacement work.
Selection starts with the shaft diameter, the housing bore and the width you can accommodate. The lip needs a ground, lubricated surface to run on; a worn shaft may call for a wear sleeve or a different mounting position. Coating the lip with a compatible grease before fitting helps limit initial wear. Keep shaft and housing perpendicular and avoid impact during installation. For high vibration or temperature, ask about material options.
Seals in this family are identified by their main dimensions and lip type. Manufacturers use their own codes, but a 50X72X7 single-lip seal can cross to another of the same size and layout when the elastomer and metal case suit the fluid and operating temperature. Dimensions alone do not settle it: check lip style, spring and material too. MR Industrial Accessories LLC can validate interchangeability for you.
To request a quote, send the complete code from the seal or the equipment nameplate by WhatsApp or email. Without a code, provide shaft and housing dimensions plus the width, and a photo of the part. With that information we identify the SKF HMSA7P2 R reference you need and reply promptly, and we can also suggest equivalents and help you choose.

Frequently asked questions
- How do I identify the seal I need?
- Measure the shaft diameter, the housing bore and the seal width. With those three measurements and the code on the seal, we can locate the exact reference. If there is no code, send a photo and the measurements by WhatsApp.
- What does the HMSA7P2 R designation mean?
- It is SKF's internal designation for this category of radial shaft seals. It covers lip type, elastomer material and construction variants. You do not need to decode it to select a seal: the dimensions and the complete code are sufficient.
- Can I replace a seal from another brand with this SKF one?
- Yes, when the main dimensions and lip type match. Also check the material and the spring, since they must suit the fluid and temperature. Send us the original code and we will confirm the equivalence.
