The DBH 6724Pol is a radial shaft seal sized for a 73 mm shaft, a 100 mm housing bore and a 16.00 mm width. It keeps lubricant inside the assembly and keeps dust, water and other particles out. Because it carries both a sealing lip and a dust lip, the Lx-R version suits equipment that runs in dirty or wet surroundings, such as gearboxes, pumps and electric motors.

Reading the designation helps when you order. The number 6724Pol identifies the seal itself, while the three measurements that matter at the bench are shaft 73 mm, housing 100 mm and width 16.00 mm. Lx-R tells you what sits inside: a main lip that holds oil or grease against the rotating shaft, plus an auxiliary lip that slows contaminants on their way toward the sealing zone. An internal spring keeps the main lip loaded against the shaft and absorbs small amounts of eccentricity.

Typical installations are gearboxes, centrifugal pumps, electric motors, mixers, conveyors and process or agricultural machinery where rotation is continuous and dirt is present. Splash zones are another common case, since the second lip adds a barrier. Treat the seal as a wear part: inspect it during scheduled maintenance and replace it once leakage starts or the elastomer has hardened.

Before fitting a new one, confirm the shaft is clean and free of burrs or scratches and that the bore is undamaged. Coat the lip with the same oil or grease the equipment uses, then press the seal in square to the shaft rather than at an angle. On a worn shaft, a seal with the lip running in a different position is worth considering. Speed, temperature and the fluid being sealed all influence which variant fits.

For an equivalent, send part number 6724Pol along with the shaft, housing and width figures, plus a photo of the removed seal. MR Industrial Accessories can then check alternatives in the same brand or in another brand it supplies, and can look into material or lip design options that exist in the catalog. The goal is to keep the machine running instead of waiting on a small wear part.

MR Industrial Accessories supplies the DBH brand. If the part number is already known, send it over WhatsApp or email and the team will prepare a quote. If the size is uncertain, share the equipment details and they will help confirm the reference and suggest equivalents.
