The DBH 8821 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. With 35 mm shaft diameter, 50 mm housing diameter and 7 mm height, and Lx design, it is press-fitted into the housing and runs on the shaft. It is used in gearboxes, pumps, electric motors and transmission equipment to prevent leaks and the entry of dust or water.

This item is a DBH 8821 radial shaft seal, identified by its designation 8821. Its dimensions are 35.00 mm shaft diameter (d), 50.00 mm housing diameter (D) and 7.00 mm height (h). The Lx design corresponds to a seal with a sealing lip and metal body, intended for press fitting into the housing. The DBH brand is a brand that MR carries, so the code 8821 is maintained for replacement and technical consultation.

Typical applications of a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, transmission shafts and process equipment. In all cases, the seal prevents lubricant leakage and protects bearings and gears from the entry of contaminants. It is a wear part that should be replaced when a leak appears or when the lip shows hardening or wear.

To install it, verify that the shaft has the 35 mm dimension and the housing 50 mm, with the 7 mm height available. The shaft surface must be clean, free of burrs and marks, and it is advisable to lubricate the lip before inserting it. The seal is placed perpendicular to the shaft and is seated with a suitable tube or shim, without striking the lip directly. If the housing shows wear, consider a neighboring size or a seal with a sleeve.
