The DBH 5501 radial shaft seal is a lip seal that blocks the passage of lubricant and prevents the entry of dust, water or particles in equipment with a rotating shaft. Due to its dimensions of 17.10 mm shaft, 28.55 mm housing and 6.35 mm height, with Mt design, it is mounted in gearboxes, pumps, electric motors and compact-size transmissions. MR Accesorios Industriales carries this official brand and advises you so you choose the correct seal according to the shaft, housing and type of service.

This item is a DBH 5501 radial shaft seal, identified by its 5501 designation. Its published attributes are: shaft diameter 17.10 mm, housing diameter 28.55 mm, height 6.35 mm and Mt design. That combination defines a small-section seal, intended for shafts up to 17 mm nominal diameter. The Mt design corresponds to a single lip configuration with spring, suitable for retaining oil or grease in continuous rotation applications. If you need to confirm tolerances or lip material, we verify it against the manufacturer's data sheet before quoting.

Typical applications of a seal of this size appear in equipment where radial space is limited: small gearboxes, low-power centrifugal pumps, single-phase electric motors, worm gear reducers, machine tool spindles and belt drives. It is also used in rollers, mixers and laboratory equipment. In all cases it fulfills the same function: keeping lubricant inside the housing and preventing the entry of contaminants that accelerate wear of bearings and gears.

To install a radial shaft seal, three points must be checked. First, that the shaft diameter and housing diameter match the values on the data sheet; a difference of tenths causes leaks or excessive fit. Second, the condition of the shaft surface: it must be polished and free of burrs, because the lip rests there and any mark damages it. Third, prior lubrication of the lip and the use of a guide sleeve so as not to invert it during insertion. If the equipment works with high peripheral speed or temperature, it is advisable to evaluate a different compound.

If code 5501 is not the one you need, we can look for a nearby size or an equivalent within the same category of radial shaft seals. To do so, send us via WhatsApp the shaft diameter, housing diameter and height you measured with a caliper, plus a photo of the old seal and the housing. With that data we review alternatives in the brands we carry and confirm whether there is a compatible option. The more precise the measurement, the faster we close the quote.

MR Accesorios Industriales has more than 80 years in the sector and carries the DBH brand as an official brand.
