This DBH 9977/85 oil seal has an inner diameter of 31 mm, an outer diameter of 47.65 mm and a height of 7.50 mm. Its A 016 design corresponds to a single-lip seal with a spring, made of an elastomer resistant to oils and greases. The designation 9977/85 identifies the series and the exact size, which makes it easier to find replacements. It is a key part for maintaining sealing integrity in applications with rotating motion.

It is commonly used on transmission shafts, centrifugal pumps, compressors, electric motors and gearboxes. It is also found in equipment in the food, chemical and petrochemical industries, where reliable sealing prevents unplanned downtime. Its ability to withstand moderate speeds and low pressures makes it versatile for multiple mechanical configurations.

For correct installation, check that the shaft has no burrs or excessive wear and that the housing is clean and undamaged. Lubricate the lip with the same oil or grease used in the equipment before inserting it, and make sure the spring is on the side of the fluid to be retained. The selection must consider the rotation speed, the operating temperature and the chemical compatibility of the elastomer with the fluid.
