The DBH 5501 radial shaft seal is a lip seal that closes off lubricant and blocks the ingress 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 fitted in gearboxes, pumps, electric motors and compact-size transmissions. MR Accesorios Industriales supplies this brand and advises you so you choose the correct radial shaft seal according to the shaft, the housing and the type of service.

This item is a DBH 5501 radial shaft seal, identified by its designation 5501. 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 the lip material, we verify it against the manufacturer's data sheet before quoting.

Typical applications for a radial shaft 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 performs the same function: keeping the lubricant inside the housing and preventing contaminants from entering that accelerate wear on bearings and gears.

To install a radial shaft seal, three points must be checked. First, that the shaft and housing diameters match the values on the data sheet; a difference of tenths causes leaks or excessive interference. Second, the condition of the shaft surface: it must be polished and free of burrs, because the lip runs on it and any mark damages it. Third, prior lubrication of the lip and the use of a guide sleeve so it is not inverted on entry. If the equipment runs at high peripheral speed or temperature, a different compound should be evaluated.

If code 5501 is not the one you need, we can look for an equivalent within the same radial shaft seal category. For that, send us by WhatsApp the shaft diameter, the housing diameter and the 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 supply and tell you the compatible option. The more precise the measurement, the faster we close the quote.

MR Accesorios Industriales supplies the DBH brand as a brand. If you already have code 5501 at hand, write to us by WhatsApp and we will send you the quote. If you are unsure between two sizes, we can also help you define which one corresponds according to the equipment and the type of lubricant it uses. We handle technical inquiries Monday to Friday and ship throughout the country.
