The DBH 8239 radial shaft seal is a lip seal that mounts in the housing and seals against the shaft to retain lubricant and block the ingress of dust, water or particles. Its Lx-R AH design combines a sealing lip with a dust lip, making it suitable for equipment exposed to moderate contamination. It is used in gearboxes, pumps, electric motors and conveyor rollers, among other industrial applications.

This item is a DBH 8239 radial shaft seal with 148 mm shaft diameter, 170 mm housing diameter and 15.00 mm height. The Lx-R AH design indicates a configuration with a sealing lip and an auxiliary exclusion lip, intended to retain oil or grease while also stopping contaminants from entering from the outside. DBH is an official brand that MR carries, so the product is identified by its code 8239 and confirmed against the manufacturer's data sheet.

Typical applications for a seal of this size include gearboxes, speed reducers, centrifugal pumps, electric motors, rollers and transmission equipment. In all cases, the seal works on a rotating shaft and inside a fixed housing, separating two environments: the lubricated interior and the exterior. Its function is to prevent lubricant leaks and protect bearings or bushings from the ingress of dust, wash water or chips.

To install a radial shaft seal, verify that the shaft and housing are clean, free of burrs and deep marks, and that the shaft surface has the appropriate hardness and roughness. The seal must enter perpendicular to the shaft, without blows that deform the lip, and be lubricated before assembly. Selection depends on rotation speed, working temperature and fluid type; if these data are not in the record, they are confirmed against the manufacturer's data sheet.
