The DBH 8865 radial shaft seal is a lip seal that mounts on a 6 mm shaft and inside a 22 mm housing bore, with a total height of 8 mm. Its Lx design combines a sealing lip with a spring that maintains pressure on the shaft, and its outer metal case ensures a firm fit in the housing. It is used to retain lubricant and block the ingress of dust, water or particles in small rotating equipment.

This item is a seal from the DBH brand, identified by part number 8865. Its dimensions are shaft (d) 6 mm, housing bore (D) 22 mm and height (h) 8.00 mm. The Lx design corresponds to a seal with a sealing lip and spring, with a construction configuration that allows it to work at moderate peripheral speeds and normal machining tolerances. The 6 mm inner diameter fits shafts with h11 tolerance or similar, while the 22 mm outer diameter fits into a bore with H8 tolerance.

Typical applications for this oil seal include small electric motors, water pumps, gear reducers, transmission shafts, fans and automation equipment. It is also found in power tools, office machines, medical equipment and centralized lubrication systems. In all cases, its function is to prevent oil or grease leaks and protect bearings and gears from the ingress of external contaminants.

To correctly select this oil seal, verify that the shaft diameter and housing bore diameter match the dimensions indicated. The shaft surface must be ground and have a minimum hardness of 45 HRC to prevent premature lip wear. The housing must have an entry chamfer and adequate surface roughness so as not to damage the lip during installation. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and make sure the spring is on the side of the fluid to be retained.
