The DBH 8691 radial shaft seal is a lip seal designed to retain lubricant and exclude contaminants on rotating shafts. Due to its dimensions, it is mounted in 76.10 mm diameter housings and 44 mm shafts, with a height of 12.70 mm. It is a common replacement part in gearboxes, pumps and transmission equipment, where shaft sealing prevents leaks and the entry of dust or water into the bearing.

This item is a DBH 8691 radial shaft seal, with the following dimensions: shaft diameter 44 mm, housing diameter 76.10 mm and height 12.70 mm. The Lz design corresponds to a lip configuration with spring and dust lip, designed to retain oil or grease and, at the same time, stop particles from entering from the outside. The lip rests on the shaft with a slight interference to ensure sealing during rotation.

Seals of this size are used in equipment with transmission shafts, such as gearboxes, centrifugal pumps, mixers, conveyors and agricultural or road machinery. They also appear in electric motors and in assemblies where a bearing must be protected from moisture and dust. When the seal loses elasticity or the lip wears, it begins to lose lubricant and the bearing is exposed to premature failure.

To select the correct seal, verify that the three dimensions match the shaft, housing and available depth. The shaft surface must be ground and free of burrs; a mark or deep scratch ruins the lip in a few hours. When mounting, lubricate the lip with the same grease or oil used in the equipment, seat the seal perpendicular and tap on the outer edge with a suitable tube or spacer, never on the lip. If the housing has a chamfer, respect full seating.
