The DBH 9946Tef radial shaft seal is a lip seal designed to prevent lubricant leaks and the ingress of contaminants in rotating equipment. It is installed in cylindrical housings and runs on a rotating shaft, with a flexible lip that maintains dynamic contact. It is a key part in pumps, motors, gearboxes and transmission systems, where sealing extends the service life of bearings and gears. MR Accesorios Industriales carries this reference as part of its seals and oil seals line.

This item is a radial shaft seal from the DBH brand, identified with the part number 9946Tef. According to the product page data, it is intended for a shaft of 79 mm in diameter. The A 352-R AH design corresponds to a specific lip and case configuration defined with the manufacturer. The housing and height values shown are not valid for selection; therefore, to confirm the final mounting dimensions, the current DBH technical data sheet must be consulted.

Radial shaft seals like this one are used in equipment with rotating motion and the need to retain oil or grease. Typical applications: centrifugal pumps, electric motors, gearboxes, transmission shafts and machine tools. Also in applications exposed to dust or water, where the lip must seal against the environment. The choice of lip material and spring depends on temperature, speed and the fluid to be retained.

To install a seal, you must verify the shaft diameter, the housing diameter and the width. The lip must be lubricated and undamaged; it is recommended to use an installation tool that does not deform the case. Shaft runout and surface finish affect service life. If the seal replaces another one, it is advisable to compare the lip design and the type of elastomer. If in doubt, consult your supplier.
