When a shaft seal starts weeping, the DBH 9169/85 is a direct replacement for a 25 mm shaft, 40 mm housing bore and 8.20 mm overall height. This radial lip seal keeps oil or grease in and dirt or water out of rotating assemblies. MR supplies this brand and helps you match the seal to the application.

The 9169/85 code covers an A 016 style seal: a single lip with a spring, intended for rotating shafts that run with lubrication. The three critical dimensions are shaft 25 mm, housing 40 mm and height 8.20 mm. The lip material is typically nitrile rubber (NBR), which handles mineral oils and greases. Before you install a replacement, confirm all three dimensions against the shaft and bore.

You will find this seal on electric motors, centrifugal pumps, gearboxes, compressors, machine tools and power transmission units. Its job is to hold lubricant in and block abrasive particles that would otherwise shorten bearing and gear life. It also appears in industrial washers, mixers and conveyors where dust or water is present. Replacing it on a regular basis is a low-cost way to protect the equipment.

Installation is straightforward if you keep the shaft clean and free of burrs. Lubricate the lip with the same oil or grease used in the machine, then press the seal squarely into the housing until it bottoms out. Avoid hitting the lip or distorting the spring. When choosing a seal, consider shaft speed, operating temperature and the fluid being sealed, not just the dimensions. If the original had a double lip or a dust guard, keep that design.
