The DBH 8728/85 radial shaft seal is a lip seal that closes the passage of oil or grease between a rotating shaft and its housing. It is used in gearboxes, pumps, electric motors and transmission equipment to prevent leaks and the entry of dust or water. Its dimensions of 22.20 mm shaft, 50.80 mm housing and 10.80 mm height, with Mx design, make it suitable for assemblies where axial space is limited and a reliable seal is needed.

This item is a seal from the DBH brand, identified by the code 8728/85. Its dimensions are 22.20 mm shaft diameter (d), 50.80 mm housing diameter (D) and 10.80 mm height (h). It corresponds to the Mx design, which defines the geometry of the lip and the outer body. It is a single-lip radial seal, designed to retain lubricant and exclude contaminants in equipment with rotating motion.

It is used in applications where there is a shaft rotating inside a housing: gearboxes, centrifugal pumps, electric motors, spindles and transmission mechanisms. It also appears in equipment in the food, chemical and process industries, provided the lip material is compatible with the fluid and the working temperature. It is a wear part that should be replaced when leaks or ingress of dirt are detected.

To select it, verify that the shaft and housing dimensions match those of the assembly. The Mx design determines the type of lip and its orientation, so it is advisable to check the manufacturer's data sheet if you have doubts. During installation, lubricate the lip, avoid hitting it and make sure the shaft has no burrs or marks that could damage the seal. Careful cleaning of the housing and shaft extends the service life of the seal.
