A radial shaft seal from the DBH line, the 9966 keeps lubricant where it belongs and keeps dust, water and particles out. It presses into the housing and its lip rides on the shaft. With a 15.90 mm shaft, 36.50 mm housing and 8.75 mm height, it fits small and mid-size assemblies such as motors, pumps, gearboxes and power tools. MR Industrial Accessories supplies it and helps you confirm the right choice for your application.

The 9966 is an Lr design: a metal outer body with a sealing lip, made to be press fitted into the housing bore. In the DBH numbering, 9966 identifies this particular size. Confirm the three measurements against your equipment before ordering, because even a few tenths of a millimeter off can block installation or allow leakage.

Sizes in this range show up in small electric motors, centrifugal pumps, gearboxes, compressors, machine tools and power transmission equipment. The seal does two jobs at once: it holds oil or grease inside the assembly and blocks outside contamination. On a rotating shaft with permanent lubrication, a correctly installed lip running on a ground surface can hold its sealing function for thousands of hours.

Selection depends on more than the dimensions. Consider shaft speed, operating temperature and the lubricant in use, since the lip compound has to suit the fluid, and a mineral oil, a synthetic lubricant and a hydraulic fluid are not interchangeable in that respect. The shaft surface should be ground and free of grooves, and shaft-to-housing concentricity matters. Where vibration or internal pressure is high, a reinforced design or a secondary lip may be worth evaluating.

If the exact size is not available or you need an equivalent, send the code 9966 or the three dimensions by WhatsApp. We check the matching options in the DBH line and in other brands we supply, then confirm the compatible alternative. We can also guide you on lip material and installation method based on how the equipment runs.

MR Industrial Accessories supplies the DBH brand. For questions on application, material compatibility or fitting, message us on WhatsApp with the code 9966 and your equipment dimensions, and we will send the technical details you need to request a quote without errors.
