The DBH 9966 radial shaft seal is a lip seal that mounts in the housing and seals against 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, gearboxes and tools. At MR Accesorios Industriales we sell it and advise you on choosing the right seal for your application.

This item is a seal of Lr design with 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 metal body, designed for press fitting into the housing. The 9966 nomenclature identifies this size within the DBH line. Before ordering, verify that the three dimensions match the shaft and housing of your equipment, because a difference of tenths can prevent installation or cause leaks.

Radial shaft seals of this size are used in small electric motors, centrifugal pumps, gearboxes, compressors, machine tools and power transmission equipment. Their function is twofold: retain the oil or grease inside the assembly and prevent 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 installation is correct.

To select a seal properly, take into account the shaft speed, working temperature and 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, which must be ground and free of grooves, as does the concentricity between shaft and housing. If the equipment operates with high vibration or internal pressure, it is advisable to evaluate a design with additional reinforcement or a secondary lip.
