The code 5279 belongs to the DBH line of radial shaft seals. The Lz variant uses a single sealing lip with a spring, a common choice for rotating shafts that run with lubrication. The 65 mm shaft, 90 mm housing bore and 10 mm height are the three values you need to match at the installation point. The DBH 5279 code makes it straightforward to find in catalogs and ordering systems. It is a standard item in the seal range MR Industrial Accessories offers.

Seals like the DBH 5279 appear in gearboxes, pumps, electric motors, transmission shafts and continuous process equipment. They also show up on machine tools, conveyors and agricultural machinery where shaft sealing matters. The seal's job is to hold lubricant in place and block contaminants from outside. In dusty, wet or washdown-heavy areas, the correct seal helps bearings last and cuts downtime.

Before installing a seal, make sure the shaft is clean and free of burrs or scratches, then lubricate the lip. Press it in evenly with a suitable tool so the spring is not damaged and the housing is not deformed. Shaft and housing runout must stay within tolerances. If the old seal failed, inspect the shaft and housing for wear. Speed, temperature and lubricant type drive the selection, so confirm those against the manufacturer's data sheet.
