The DBH 9947Tef radial shaft seal is a lip seal designed to be mounted on a 79.38 mm shaft and retain lubricant inside the housing while preventing the ingress of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment where a rotating shaft passes through a casing. Its A 353-R AH design defines the geometry of the lip and the metal body. At MR Accesorios Industriales we supply it as an official brand and quote it by WhatsApp with your code.

This item is a radial shaft seal from the DBH line, identified by the designation 9947Tef. According to the record, it corresponds to a shaft with a diameter of 79.38 mm and its design is A 353-R AH. The housing and height fields appear as 0 and 000 in the product page, so those dimensions are not published here: they are confirmed against the manufacturer's data sheet at the time of quoting. The A 353-R AH design indicates a lip and body configuration intended for oil retention in general industrial applications.

Typical applications of a radial shaft seal of this type include gearboxes, reducers, centrifugal pumps, electric motors, rollers and power transmission equipment. In all cases it performs the function of closing off the passage of lubricant to the outside and blocking the entry of contaminants. It is a wear part: over time the lip hardens or becomes marked and begins to leak. Therefore it should be checked every time the equipment is disassembled and replaced if it shows stiffness, cuts or loss of elasticity.

To install a radial shaft seal, work with a clean shaft free of burrs, lubricate the lip with the same grease or oil used in the equipment and use a tube or support bushing to insert it evenly, without hitting it from the side. If the shaft has a groove or a step, protect the lip during passage. In selection, in addition to the shaft diameter, the housing diameter, height, type of fluid, working temperature and peripheral speed matter. With that data the lip design and material are defined.

If you need a nearby size or an equivalent from another brand for the 9947Tef, send us the shaft diameter, housing diameter and height you have measured on the equipment, plus a photo of the old part if possible. With that data we search within the DBH line and among the alternatives we supply. We can also verify whether the A 353-R AH design is suitable for your application or whether another lip profile is better according to the fluid and temperature.
