The DBH 8281 radial shaft seal is a lip seal that blocks the passage of oil or grease between a rotating shaft and its housing. With a 55 mm shaft diameter, 80 mm housing diameter and a height of 11.00/14.50 mm, it is press-fitted into crankcases, covers and gearboxes. Its A 020 design combines a sealing lip with a dust lip that protects the contact area. It is a wear part: when lubricant leakage appears or dirt enters, it is replaced.

This item is a radial shaft seal from the DBH brand, identified by the code 8281. Its dimensions are 55 mm shaft diameter (d), 80 mm housing diameter (D) and a height (h) of 11.00/14.50 mm. The A 020 design corresponds to a seal with a double lip: one sealing lip facing the oil and one dust lip facing outward. The height expressed as a range indicates that the outer lip protrudes from the housing, so it is advisable to verify the cavity depth before installing it.

It is used in equipment where a shaft passes through a lubricant-filled housing: gearboxes, reducers, pumps, electric motors, drive shafts and rollers. It also appears in applications exposed to dust or water, where the dust lip prevents contaminants from reaching the main lip. It is common in maintenance of agricultural, textile, food and transport machinery, provided the shaft and housing are in good condition.

To select the correct seal, in addition to the dimensions, take into account the shaft speed, working temperature and type of lubricant. A scratched, worn or burred shaft destroys the lip within hours: it is advisable to inspect the surface before installation and, if necessary, use a wear sleeve. The housing must be clean, free of burrs and with the correct diameter so that the seal seats without deforming. Lubricate the lip with the same grease or oil used in the equipment before inserting it.
