The DBH 9966 radial shaft seal is a lip seal mounted in the housing and closing on the shaft to retain lubricant and block the entry of dust, water or particles. Its dimensions of 15.90 mm shaft, 36.50 mm housing and 8.75 mm height place it in small and medium-sized equipment, such as electric motors, pumps, reducers and tools. At MR Accesorios Industriales we carry it as an official brand and advise you on choosing the right seal for your application.

This item is a seal with an Lr design and the following dimensions: shaft diameter 15.90 mm, housing diameter 36.50 mm and height 8.75 mm. The Lr design corresponds to a seal with a sealing lip and a metal case, intended for press-fit mounting in the housing. The 9966 nomenclature identifies this size within the DBH line. Before ordering, check that the three dimensions match the shaft and housing of your equipment, because a difference of tenths of a millimetre can prevent mounting or cause leaks.

Radial shaft seals of this size are used in small electric motors, centrifugal pumps, reducers, compressors, machine tools and transmission equipment. Their function is twofold: to retain the oil or grease inside the assembly and to keep contaminants from entering from outside. In applications with a rotating shaft and permanent lubrication, the lip runs on a ground surface and maintains sealing for thousands of hours if mounting is correct.

To select a seal properly, take into account the shaft speed, the working temperature and the type of lubricant. The lip material must be compatible with the fluid: a mineral oil is not the same as a synthetic lubricant or a hydraulic fluid. The surface finish of the shaft also matters, as it must be ground and free of grooves, along with the concentricity between shaft and housing. If the equipment operates with heavy vibration or internal pressure, it is advisable to consider a design with additional reinforcement or a secondary lip.

If you cannot find the exact size or need an equivalent, send us part number 9966 or the three seal dimensions by WhatsApp. At MR Accesorios Industriales we compare against the alternatives available in the DBH line and in other brands we carry, and confirm whether a compatible neighbouring size exists. We can also advise you on lip material and mounting type according to the use you will give it.
