The DBH 9947Tef is a radial shaft seal that fits a 79.38 mm shaft. Its purpose is to keep lubricant in and contaminants out where a rotating shaft exits a housing. The A 353-R AH designation describes the lip and case geometry. MR Industrial Accessories supplies this seal and can quote it from the part number you send by WhatsApp or email.

You will find the 9947Tef in gearboxes, pumps, electric motors, rollers and other transmission equipment. As a wear part, the lip can harden, crack or lose elasticity over time, leading to leaks. Inspect it whenever the equipment is opened and replace it if it shows stiffness, cuts or a worn edge.

For installation, start with a clean shaft free of burrs. Lubricate the lip with the same oil or grease used in the unit, then press the seal in evenly with a tube or bushing. Avoid angled blows. If the shaft has a groove or step, protect the lip as it passes over.

When selecting a replacement, the shaft diameter is only one factor. The housing bore, seal height, fluid type, operating temperature and peripheral speed all influence the lip design and material. The A 353-R AH configuration is intended for general oil retention, but other profiles may suit different conditions.
