The dimensions of this seal are 55x78x10mm. Find more details on the 55X78X10 HMSA10RG below.

Key Features

Enhanced Rubber Outside Diameter (RG)

The outside diameter of the 55X78X10HMSA10RG is made of SKF’s optimized nitrile rubber compound (RG), Acrylonitrile-butadiene, which has been designed following developments in sealing material research. Nitrile rubber can be used in applications with oil or grease lubrication in temperatures ranging from -40oC to 100oC (-40oF to 210oF), or up to 120oC (250oF) for short periods of time. This nitrile rubber has greatly extended service life compared to standard NBR and high-performance NBR compounds, reducing the need for maintenance and replacement.

Improved Sealing Performance

HMSA10 seals like the 55X78X10 HMSA10RG offer improved sealing performance through features like an optimized rubber outside diameter and spring-loaded sealing lips. These elements ensure effective sealing even in challenging conditions, such as considerable surface roughness or split housings. The auxiliary lip enhances sealing capability without impacting operating speeds.

Versatile Applications

No matter your industry, the SKF 55X78X10HMSA10RG is able to support your applications sealing requirements. It’s design and ISO 6194-1 and DIN 3760 compliance make this HMSA10 shaft seal suitable for a wide range of industrial applications.
