The DBH 5259 radial shaft seal is a lip seal that mounts on the shaft and closes against the housing to retain lubricant and block the entry of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment where a rotating shaft exits a crankcase. Its dimensions of 19 mm shaft, 38.07 mm housing bore and 9.92 mm height correspond to the Lz design, with rubber lip and metal case. MR Accesorios Industriales carries it as an official brand.

This item is a radial shaft seal of the DBH brand, identified with the code 5259. Its dimensions are 19 mm shaft diameter, 38.07 mm housing bore and 9.92 mm height. The Lz design indicates the construction of the lip and case according to the manufacturer's designation. It is a compact-section seal, intended for small-diameter shafts where axial space is limited. It is supplied as an individual part and is press-fitted into the housing.

Typical applications for a seal of this size include small gearboxes, centrifugal pumps, low-power electric motors, compressors and belt or chain transmission equipment. It also appears in machine tools, washing equipment and irrigation systems. In all cases it fulfills the function of retaining the oil or grease inside the crankcase and preventing contaminants from entering from outside, extending the life of bearings and gears.

To correctly select a seal, you must verify the shaft diameter, the housing bore and the available height. These three dimensions must match those of the 5259 seal: 19 mm, 38.07 mm and 9.92 mm respectively. In addition, it is important to check the condition of the shaft surface: it must not have burrs, scratches or excessive wear, because the lip needs a smooth track to seal. When installing it, lubricate the lip with the same oil used in the equipment and place the seal perpendicular to the shaft, without striking it directly.

If you need a seal with equivalent dimensions or a nearby size, you can consult us. Sometimes the housing accepts a seal of slightly different height or another lip design. For that, send us the 5259 code or the shaft, housing bore and height dimensions, and we will confirm the available alternatives. We can also advise you on the most suitable design according to the type of lubricant and the working conditions.

At MR Accesorios Industriales we carry the DBH brand as part of our line of seals and oil seals.
