The DBH 8402Pol radial shaft seal is a lip seal that mounts on the shaft and blocks the passage of oil, grease or contaminants in gearboxes, pumps and motors. Its Lx-R design combines a sealing lip and a dust lip, making it suitable for equipment with moderate exposure to dust or dirt. With a 36 mm shaft, 50 mm housing and 8 mm height, it is a commonly used size in industrial maintenance.

This DBH 8402Pol oil seal has a shaft diameter of 36 mm, a housing diameter of 50 mm and a height of 8.00 mm. The Lx-R design indicates that the seal has a main sealing lip and a secondary exclusion lip, designed to retain lubricant and stop particles from entering from the outside. DBH is an official brand that MR carries, so the replacement part is identified by its original part number to avoid confusion when replacing it.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission equipment. In all these cases, the seal keeps the lubricant inside the assembly and prevents dust or water from entering the bearing or the shaft. It is a wear part that should be checked when oil leaks or abnormal noises appear in the sealing area.

To correctly select the replacement, verify that the three dimensions match the housing and the shaft: 36 mm shaft, 50 mm housing and 8 mm height. Also check the condition of the shaft surface: if it shows wear, scratches or a marked track, the new lip will not seal properly and you should consider a repair sleeve or a seal with an offset lip. The Lx-R design is suitable when there is exposure to dust; if the equipment operates under high pressure or speed, consult us before replacing.

If you cannot find the 8402Pol part number or need a nearby size, send us the dimensions of the old seal — shaft diameter, housing diameter and height — and the type of application.

We can also advise you on the most suitable lip design depending on the type of lubricant and the equipment's operating conditions.
