The DBH 8871 radial shaft seal is a lip seal that blocks the passage of oil, grease or contaminants on rotating shafts. Due to its dimensions —19 mm shaft, 35 mm housing and 7 mm height— it is used in gearboxes, pumps, electric motors and power transmission equipment. Its Lx design combines a sealing lip with a metal case that fits into the housing under pressure. MR Accesorios Industriales sells this brand and helps you choose the correct size.

This item is a radial shaft seal from the DBH brand, identified with part number 8871. According to the product page data, it has a shaft diameter (d) of 19 mm, a housing diameter (D) of 35 mm and a height (h) of 7.00 mm. The Lx design corresponds to a seal with a single sealing lip and an outer metal case, designed to be press-fitted into the housing with the lip resting on the rotating shaft.

Typical applications for a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all cases it serves to retain the lubricant inside the assembly and prevent the entry of dust, water or particles that accelerate wear on bearings and gears. It is also used as a secondary closure on fan and agitator shafts.

To correctly select a seal, you must verify the shaft size, the housing diameter and the available width. Rotation speed, working temperature and the type of fluid to be retained determine the lip and spring material. During installation, it is advisable to clean the housing, lubricate the lip with the same oil used in the equipment and avoid striking the case. If the shaft shows wear or roughness, consider a repair sleeve or an alternative size.
