The DBH 8073 radial shaft seal is a lip seal mounted in the housing and sealing against the shaft to retain lubricant and stop the entry of dust, water or particles. Its A 117-Hel design combines a sealing lip with a stepped-height body, allowing it to cover two mounting heights depending on housing depth. It is used in pumps, electric motors, gearboxes and power transmission equipment where the shaft rotates with slight misalignment.

This item is identified as DBH 8073 seal, with the following dimensions taken from its product page: shaft diameter 20 mm, housing diameter 35 mm and height 7.00/10.60 mm. The A 117-Hel design corresponds to a lip seal with spring and double-height body, designed for housings with a shoulder or to replace seals of different depths without modifying the machining. The designation 8073 is the code you will use to order it or to search for an equivalent.

Typical applications for a seal of this size include small centrifugal pumps, low-power electric motors, parallel-shaft reducers, screw compressors and belt or chain drive equipment. In all these cases the seal serves two functions: preventing oil or grease from leaking outward and blocking the entry of contaminants that accelerate wear on the bearing or bushing. It is also used as a secondary seal in gearboxes and machine tool spindles.

To select and install a radial shaft seal, verify three things: that the shaft diameter is within the recommended tolerance, that the housing has the correct diameter and depth, and that the shaft peripheral speed is compatible with the lip material. The lip must be lubricated before installation and the seal must enter perpendicular, without blows that deform the spring. If the shaft shows wear or grooves, consider a repair sleeve before forcing the seal.

If you need an equivalent, the most practical approach is to send us code 8073, the equipment brand and the shaft and housing dimensions. With that data we can compare with other seal series, verify the lip design and propose an alternative that fits the existing machining. We can also check whether the same seal is available in a different height or with a different lip material depending on the fluid and working temperature.

At MR Accesorios Industriales we sell the DBH brand as part of our line of seals, along with bearings, housings, power transmission, bushings, mounting tools and lubricants.
