The DBH 8617Pol radial shaft seal is a lip seal that mounts on the shaft and seals against the housing to retain lubricant and block the entry of dust, water or particles. Its Lx-H-AH design combines a sealing lip with a reinforced body, intended for equipment with continuous rotation and exposure to dirt. It is used in gearboxes, pumps, electric motors and transmissions where the shaft rotates on bearings or bushings and a reliable barrier is needed.

This DBH 8617Pol seal has a 105 mm shaft diameter, a 142 mm housing diameter and a 13.00 mm height. The Lx-H-AH design indicates the geometry of the lip and the body: a profile that seals on the shaft and seats in the housing with a reinforced section. DBH is an official brand that MR carries, so the part number is ordered exactly as it appears on the product page. Before mounting, verify that the shaft and housing have the dimensions and surface finish required by the manufacturer.

Typical applications for a seal of this size appear in equipment with medium-section shafts: gearboxes and gear units, centrifugal pumps, electric motors, mixers, conveyors and machine tools. It is also used as a closure on roller or ball bearings mounted in split housings, where the seal prevents lubricant from escaping and dust from entering the raceway. If the equipment operates with heavy vibration or temperature, it is advisable to check the condition of the shaft before replacing the seal.

To properly select a radial shaft seal, the size alone is not enough: rotational speed, operating temperature, type of lubricant and differential pressure all matter. The Lx-H-AH design is usually chosen when there is external dirt and a lip with good wear resistance is sought. During mounting, lubricate the lip, avoid striking it and make sure it seats perpendicular to the shaft. If the housing is damaged or the shaft has grooves, the new seal can fail within a few hours.
