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

This item is identified as DBH 8073 oil seal, with the following dimensions taken from its data sheet: 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 a double-height body, intended for housings with a step or to replace oil 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 an oil seal of this size include small centrifugal pumps, low-power electric motors, parallel-shaft gearboxes, screw compressors and belt- or chain-driven transmission equipment. In all these cases the oil seal serves two functions: preventing oil or grease from leaking to the outside and blocking the ingress of contaminants that accelerate wear on the bearing or bushing. It is also used as a secondary seal in gearboxes and in machine tool spindles.

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

If you need an equivalent or a close size, the most practical thing is to send us the code 8073, the equipment brand and the shaft and housing dimensions. With that data we can compare with other oil seal series, verify the lip design and propose an alternative that fits the existing machining. We can also check whether the same oil 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 carry the DBH brand as part of our line of seals and oil seals, along with bearings, housings, power transmission, bushings, mounting tools and lubricants.
