The DBH 8873 radial shaft seal is a lip seal that is fitted in the housing and seals against the rotating shaft to retain lubricant and block the entry of dust, water or particles. Its Lx design and its dimensions of 20 mm shaft, 37 mm housing bore and 10 mm height place it in small and medium-sized equipment. It is used in pumps, electric motors, gearboxes and transmissions where bearings and gears must be protected.

This item is a radial shaft seal from the DBH line, identified by the code 8873. Its nominal dimensions are 20.00 mm shaft diameter (d), 37.00 mm housing bore (D) and 10.00 mm height (h). The Lx design corresponds to a single-lip seal with spring, intended for rotating shafts with lubrication. DBH is a brand MR sells, so the replacement part arrives with its original designation and can be checked against the manufacturer's product page.

Typical applications for a seal of this size appear in centrifugal pumps, electric motors, gear reducers, mixers and power transmission equipment. It is also found on fan shafts, small compressors and process machinery. In all cases it performs the same function: keep the oil or grease inside the assembly and prevent contaminants from entering that accelerate wear on bearings and gears.

To select it correctly, check that the shaft diameter and the housing bore match the 20 mm and 37 mm indicated, and that the 10 mm height fits into the cavity. The Lx design is chosen when the lip works on a rotating shaft with lubricant and the speed is moderate. Check the condition of the shaft: a scratched or burred surface ruins the new lip. Lubricate the lip before installing and press the seal in evenly, without striking it from the side.

If the code 8873 is not the one you need, or if the shaft or housing bore has a different dimension, send us the equipment data or the old dimension. At MR Accesorios Industriales we can look for an equivalent within the same DBH line or a size that fits the housing. The more data you send us — shaft diameter, housing bore, height and type of lubricant — the faster we can get you the right option.
