The DBH 9977/85 is a radial shaft lip seal built to keep lubricants in and contaminants out of rotating equipment. Its dimensions are 31 mm for the shaft, 47.65 mm for the housing bore and 7.50 mm for the width. The A 016 profile is a single-lip design with a spring, made from an elastomer that resists oils and greases. This seal fits gearboxes, pumps, electric motors and other industrial machinery where a dependable barrier against dust, water and particles is needed.
The part number 9977/85 points to a specific series and size, which simplifies the search for a replacement. The seal's shaft diameter is 31 mm, its housing bore is 47.65 mm and its width is 7.50 mm. These measurements are standard for this size, so the seal drops into equipment that calls for this exact fit. It is a critical component for maintaining sealing integrity in rotating assemblies.
Typical installations include transmission shafts, centrifugal pumps, compressors, electric motors and gearboxes. The seal also appears in food, chemical and petrochemical plants, where a failed seal can mean unplanned downtime. It handles moderate speeds and low pressures, which makes it suitable for a range of mechanical setups.
Proper installation starts with inspecting the shaft for burrs or wear and making sure the housing is clean and undamaged. Lubricate the lip with the same oil or grease used in the equipment, then insert the seal with the spring facing the fluid side. When selecting a seal, consider the rotation speed, operating temperature and chemical compatibility of the elastomer with the fluid.
