For rotating shafts in industrial equipment, the DBH 9252/85 seal keeps lubricant in and contaminants out. With a shaft fit of 15.70 mm and a housing bore of 42.10 mm, its stepped profile of 3.30/10.00 mm suits compact installations. MR supplies this seal as part of its seals line for maintenance and repair work.

The part number 9252/85 identifies a lip seal in the DBH line with design A 119. The shaft side measures 15.70 mm, while the outer diameter that presses into the bore is 42.10 mm. The overall height is not uniform: it steps from 3.30 mm at the lip to 10.00 mm at the body, giving a stable seat in shallow cavities. A steel spring keeps the sealing lip in contact with the shaft, and the elastomer outer surface holds the seal in the housing.

This seal is a practical choice for gearboxes, centrifugal pumps, electric motors, compressors, and belt or chain drives. In each case, it prevents oil or grease from escaping and stops dust, water, or debris from reaching bearings and gears. The compact dimensions are useful where axial room is tight but moderate-speed sealing is still required.

Before ordering, check that the shaft diameter falls within tolerance and that the surface finish is about 0.2 to 0.8 µm Ra. The housing should be clean, free of burrs, and have a lead-in chamfer to ease installation. Coat the lip with the system lubricant before pressing the seal in, and avoid hammering or flipping the lip. If the shaft is worn, a seal with an auxiliary lip may be considered.
