The DBH 9900 radial shaft seal is a lip seal that stops lubricant from escaping and blocks dust and moisture from entering equipment with a rotating shaft. Its dimensions of 68 mm shaft diameter, 90 mm housing diameter and 10 mm height place it in medium-sized power transmission and machinery applications. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your equipment.

This item is a radial shaft seal from the DBH line, identified with code 9900. Its dimensions are 68 mm shaft diameter (d), 90 mm housing diameter (D) and 10 mm height (h). The Kz design corresponds to a configuration with a sealing lip and metal reinforcement, intended to retain oil or grease in bearing chambers and gearboxes. It is a direct replacement part: it is press-fitted into the housing and its lip rests on the rotating shaft.

Typical applications for a seal of this size include gearboxes, centrifugal pumps, electric motors, speed reducers and belt or chain drive equipment. It is also used in agricultural machinery, conveyors and hydraulic systems where lubricant leaks and external contamination must be prevented. In all cases, the seal protects the bearings and extends the service life of the assembly, provided the shaft and housing are in good condition.

To correctly select this seal, verify that the shaft diameter is 68 mm and the housing is 90 mm, with a mounting depth compatible with the 10 mm height. The Kz design requires a polished shaft surface free of burrs, and a housing with a finish suitable for the press fit. During installation, lubricate the lip and use a tool that does not damage the seal. If the shaft shows wear, consider a repair sleeve or an alternative size.

If you need an equivalent seal or a nearby size, the most practical approach is to send us code 9900 or the current dimensions of your equipment. With that data we can look for alternatives within the same DBH brand or other lines we carry. We can also advise you if the mounting space allows height or design variants. The more information you give us — diameters, height, type of lubricant and operating conditions — the more accurate the proposal will be.
