The DBH 8417Pol radial shaft seal is a single lip radial seal, intended to retain oil or grease and exclude dust on rotating shafts. Its dimensions of 21.50 mm shaft, 40.00 mm housing and 7.00 mm height place it in compact equipment, such as small motors, pumps and light reducers. The Lz-H design combines a sealing lip with a dust lip, which improves protection in dirty environments. MR Accesorios Industriales carries it as part of its seals and radial shaft seals line.

This item is a radial shaft seal from the DBH line, identified by the code 8417Pol. Its published attributes are: shaft diameter 21.5 mm, housing diameter 40 mm and height 7.00 mm. The Lz-H design indicates a configuration with a sealing lip and a dust lip, which adds a barrier against external particles. The elastomer and the internal spring are confirmed against the manufacturer's data sheet at the time of quoting.

Typical applications for a seal of this size include small electric motors, low-power centrifugal pumps, compact shaft reducers, light gearboxes and power transmission equipment where the goal is to contain lubricant and prevent dust ingress. It is also used in machine tools, food handling equipment and irrigation systems, provided that the speed and service temperature are within the range of the compound.

To select correctly, verify that the shaft and housing diameters match the values on the data sheet. The 7.00 mm height must fit into the cavity without forcing. The Lz-H design is advisable when there is exposure to dust or chips; if the environment is clean, a single lip may be sufficient. During installation, lubricate the lip, avoid impacts on the sealing surface and make sure the shaft has no burrs or marks that could damage the elastomer.
