The DBH 5766 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks the entry of dust and moisture in equipment with rotating shafts. Due to its dimensions —33.33 mm shaft, 50.80 mm housing and 11.90 mm height— it is used in gearboxes, pumps, electric motors and industrial transmissions. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct seal according to the type of lubricant, speed and working environment.

This item is a DBH 5766 radial shaft seal, identified by its designation 5766. Its dimensions are 33.33 mm shaft, 50.80 mm housing and 11.90 mm height. The Mz design corresponds to a seal with a single sealing lip and metal body, designed for press fitting into a cylindrical housing. The DBH brand is an official brand that MR supplies, so the code 5766 corresponds to that catalogue reference.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, compressors and transmission shafts. In all cases, the seal retains the lubricant inside the assembly and prevents the entry of external contaminants, which extends the life of bearings and gears. It is commonly found in equipment where radial space is limited and reliable sealing is required at moderate speeds.

To install this seal correctly, check that the shaft and housing are clean, free of burrs and marks. Lubricate the lip with the same oil or grease used in the equipment before inserting it. The 11.90 mm height should sit flush or slightly recessed in the housing, depending on the cover design. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip. The final selection depends on speed, temperature and type of lubricant.
