This item is a radial shaft seal of the DBH brand, identified with the designation 9170/85. Its dimensions are: shaft diameter (d) 25 mm, housing diameter (D) 39.80 mm and height (h) 6.40 mm. The A 016 design indicates a single-lip geometry with spring, suitable for retaining oil or grease on rotating shafts. The sealing lip works on the shaft and the outer case is press-fitted into the housing. It is a common replacement part in industrial maintenance.

Typical applications of a seal of these dimensions include gearboxes, centrifugal pumps, electric motors, compressors and belt or chain transmission equipment. It is also found in machine tools, agitators and speed reducers. In all cases, the function is the same: prevent lubricant leaks and block the entry of dust, water or particles that accelerate wear on bearings and gears. It is an inexpensive part that protects much more costly components.

To correctly select a seal, verify that the shaft, housing and height dimensions match those of your equipment's housing and shaft. Peripheral speed, working temperature and type of lubricant influence the choice of lip material and spring. During installation, lubricate the lip with the same service oil or grease, insert it perpendicular to the shaft and avoid striking it. If the shaft shows wear or grooves, consider a repair sleeve or an alternative size.
