The DBH 5710 radial shaft seal is a lip seal that mounts in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. With its dimensions of 50.80 mm shaft, 81.00 mm housing and 11.90 mm height, and its Lx design, it is used in gearboxes, pumps, electric motors and power transmission equipment running on shafts of approximately two inches. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a seal from the DBH line, identified with code 5710. Its dimensions are 50.80 mm shaft diameter, 81.00 mm housing diameter and 11.90 mm overall height. The Lx design corresponds to a seal with a sealing lip and an outer metal body, designed to be press-fitted into the housing with the lip bearing against the shaft. It is a standard replacement part within the radial seal category, not a special development.

Typical applications for a seal of this size appear in equipment with 50.80 mm shafts: gearboxes, reducers, centrifugal pumps, electric motors, compressors and power transmission machines. In all of these cases it performs the same function: keeping oil or grease inside the assembly and preventing contaminants from entering from outside. It is also used as a closure in bearings and bushings operating in dusty or humid environments.

To select and install a seal, three things must be verified: that the shaft and housing diameters match those of the part, that the height is compatible with the housing depth, and that the lip material is suitable for the working temperature and fluid. During installation, it is advisable to lubricate the lip, insert it perpendicular to the shaft and use a tube or press that bears on the metal edge, never on the lip. A poorly seated seal leaks even when the dimensions are correct.

If you need a nearby size or an equivalent, the most practical approach is to send us code 5710 along with the shaft and housing diameters you have on the machine. With that data we search within the same DBH line or other brands we carry, and we confirm whether a compatible alternative exists. If the original seal has no visible brand, we can also identify it from measurements taken with a caliper.
