The DBH 8775 radial shaft seal is a lip seal that prevents lubricant leaks and the entry of contaminants in equipment with a rotating shaft. Its dimensions of 27 mm shaft diameter, 42 mm housing diameter and 7 mm height make it suitable for gearboxes, pumps, electric motors and transmissions. MR Accesorios Industriales sells this brand and advises you so you choose the right seal for your application.

This item is a DBH 8775 radial shaft seal, identified by its numeric designation. Its attributes indicate a shaft diameter of 27 mm, a housing diameter of 42 mm and a height of 7.00 mm. The Lx design corresponds to a configuration with a sealing lip and spring, intended to retain oil or grease on rotating shafts. The 8775 nomenclature is the code the manufacturer assigns to this particular size and design.

Radial shaft seals such as the DBH 8775 are used in gearboxes, centrifugal pumps, electric motors, rollers and belt or chain transmissions. Their function is twofold: retain the lubricant inside the equipment and block dust, water or particles that could damage the bearings. They are critical components in industrial maintenance because a sealing failure leads to lubricant loss and premature wear.

To install a seal, check that the shaft has no burrs or wear and that the housing is clean and free of dents. It is recommended to lubricate the lip before inserting it and to use an installation tube that rests on the metal edge, never on the lip. Selection depends on shaft speed, working temperature and the type of fluid to be retained; if in doubt, consult the manufacturer or a specialist.

If you need an equivalent seal, the most practical thing is to send us the 8775 code or the dimensions of your shaft and housing. You can also send a photo of the original seal or the assembly drawing. At MR Accesorios Industriales we compare that data with the corresponding options and confirm which option fits your equipment.
