The SKF HMA R series radial shaft seal is a lip seal that keeps lubricant in and contaminants out of rotating shaft applications. Its elastomer lip works with a metal case that provides rigidity for press-fit installation. The low-profile design suits tight spaces where a dependable barrier against dust, water and particles is needed. MR Industrial Accessories supplies this line and offers technical guidance to match the right size to your equipment.

Seal designations combine dimensions and suffixes. Take 18X26X4 HMA1 R: shaft 18 mm, housing 26 mm, width 4 mm. Similarly, 22X28X4 HMA10 R follows the same pattern with its own measurements. HMA denotes the compound and lip design family; the number after it (1, 10) points to variants in the series. The trailing R indicates a construction detail, such as spring type or case material. Reading these codes lets you order the exact seal.

These seals appear in pumps, electric motors, gear reducers, transmission boxes and process equipment. They serve two purposes: containing oil or grease and blocking dirt that would speed wear on bearings and bushings. Because they are wear components, inspect them at each preventive maintenance interval and replace any that show cuts, hardening or loss of elasticity.

Correct selection starts with matching the seal to both housing and shaft. The lip must run on a ground, lubricated surface; a scratched or burred shaft will damage the seal. Press the case in with the proper tool and avoid striking the lip. In high-vibration or misaligned equipment, consider a more rigid seal or a design with an auxiliary lip. Lubricating the lip before assembly helps prevent premature failure.

SKF seals can interchange with other recognized brands when dimensions, lip type and material align. Diameters alone are not enough: width and lip shape also matter. For a replacement, provide the full code from the old seal or caliper measurements. MR Industrial Accessories can help with equivalence questions, though confirming the application is always recommended to avoid compromising the seal.
