The DBH 9946Tef is a radial shaft seal that keeps lubricant inside rotating equipment and keeps dust, water and other contaminants out. It sits in a cylindrical housing bore and its flexible lip rides against the turning shaft, holding dynamic contact while the machine runs. Seals of this type protect bearings and gears in pumps, motors, gearboxes and transmission systems. MR Industrial Accessories supplies this reference within its seals and oil seals range.

This seal carries the DBH brand name and the reference 9946Tef. The published data lists it for a 79 mm shaft, and its design code is A 352-R AH, which describes a particular lip and case arrangement set by the manufacturer. The housing and height figures that appear on some listings should not be used to make a selection. Confirm the final mounting dimensions against the current DBH technical data sheet before ordering.

Seals in this family are found wherever a shaft rotates and oil or grease has to stay put: centrifugal pumps, electric motors, gearboxes, transmission shafts and machine tools, including locations where dust or water is present and the lip has to hold off the environment. Which lip compound and spring are right depends on the operating temperature, the shaft speed and the fluid being retained.

Installation calls for checking three things: shaft diameter, housing bore and width. Lubricate the lip, make sure it is free of nicks, and press the seal in with a tool that will not distort the case. Shaft runout and surface finish both influence how long the seal lasts. When replacing another seal, compare the lip profile and the elastomer type rather than the part number alone. Your supplier can help if anything is unclear.

For an equivalent, send the complete part number along with the shaft and housing dimensions. With those details we can look through the DBH line or other options that do the same job, and we can advise on lip material for your fluid and working temperature. The goal is a seal that fits your equipment without guesswork.
