The DBH 9811/85 radial shaft seal is a lip seal mounted in housings to retain lubricant and exclude contaminants in rotating equipment. Its designation 9811/85 corresponds to a seal with a 35 mm shaft, 50 mm housing and 8 mm height, with design A 016. It is used in pumps, electric motors, gearboxes and transmissions where the shaft rotates inside a housing. MR Accesorios Industriales carries 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 design A 016. That combination defines a lip seal with a metal case and elastomer, designed for rotating shafts. Design A 016 indicates a particular construction within the DBH line, which should be verified against the manufacturer's data sheet if you need details on the lip or 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 a wear component, periodic replacement prevents leaks and extends the life of nearby bearings and gears.

For installation, make sure the shaft and housing are clean, free of burrs and marks. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking the elastomer. Selection depends on rotation speed, operating temperature and the fluid to be retained; if the equipment runs 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.

At MR Accesorios Industriales we cross-check the designation against the manufacturer's data sheet to offer you the right option within the DBH line or a compatible alternative.

DBH is a brand that MR carries, so you can ask us about this reference and the rest of the seal and oil seal line. Before replacing, check the condition of the shaft: wear or a groove on the lip track can cause a new seal to fail within a short time. If you have doubts, write to us with code 9811/85 and we will help you confirm the size.
