The DBH 9811/85 radial shaft seal is a lip seal that mounts in housings to retain lubricant and exclude contaminants in rotating equipment. Its designation 9811/85 corresponds to a seal of 35 mm shaft, 50 mm housing and 8 mm height, with A 016 design. It is used in pumps, electric motors, gearboxes and transmissions where the shaft rotates inside a housing. MR Accesorios Industriales sells this brand so you can replace worn seals with a standard size.

This item is a DBH 9811/85 radial shaft seal, identified by its designation 9811/85. Its technical attributes are: shaft diameter 35 mm, housing diameter 50 mm, height 8.00 mm and A 016 design. That combination defines a lip seal with a metal case and elastomer, intended for rotating shafts. The A 016 design indicates a particular construction configuration within the DBH line, which should be verified against the manufacturer's data sheet if you need details of the lip or the material.

Typical applications for a seal of this size include centrifugal pumps, electric motors, gearboxes, reducers and power transmission equipment. In all cases it performs two functions: retaining the oil or grease inside the assembly and preventing the entry of dust, water or particles. As it is a wear component, its periodic replacement prevents leaks and extends the life of nearby bearings and gears.

To mount it, verify that the shaft and the housing are clean, without burrs or marks. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without hitting the elastomer. Selection depends on rotation speed, working temperature and the fluid to be retained; if the equipment operates at high peripheral speed or extreme temperatures, ask about the appropriate variant. The 35 x 50 x 8 mm size is the main reference for finding the replacement.
