The DBH 9879 radial shaft seal is a lip seal that mounts on the shaft and blocks the passage of oil, grease or contaminants in gearboxes, pumps and motors. Its Lx design and dimensions of 32 mm shaft, 43 mm housing and 8 mm height make it suitable for equipment where a worn seal must be replaced without modifying the machining. MR Accesorios Industriales sells this brand and advises you on choosing the right seal.

This item is a DBH 9879 radial shaft seal, identified by its numeric designation. Its attributes indicate a shaft diameter of 32 mm, a housing diameter of 43 mm and a height of 8.00 mm. The Lx design corresponds to a single-lip configuration with spring, intended to retain lubricant and exclude dust under continuous rotation conditions. The code 9879 allows it to be located within the DBH line and checked against the manufacturer's data sheet before purchase.

Radial shaft seals of this type are used in gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. They also appear in machine tools, compressors and hydraulic systems where the shaft rotates inside a fixed housing. Their function is twofold: to prevent oil leaks to the outside and to stop the ingress of water, chips or dust that accelerate wear on bearings and bushings. In food or process plants, selecting the lip material is as important as the size.

To install a seal, check that the shaft has no burrs, that the housing is clean and that the 8.00 mm height matches the available depth. It is recommended to lubricate the lip before inserting it and to use a support tube so as not to deform the spring. If the shaft has a worn track, consider a seal with an offset lip or a repair sleeve. Speed, temperature and the working fluid define the lip compound; that is why matching only the dimensions is not enough.

To quote code 9879 along with the shaft, housing and height dimensions, and a photo of the old seal, send us an equivalent from another brand. With that data we can look for an alternative within the DBH line or other brands we sell. We can also advise you if the Lx design is not suitable for your application and a different type of lip or a different material is needed.
