This item is a DBH 5178 radial shaft seal, identified by its designation 5178. Its dimensions are shaft (d) 35 mm, housing (D) 54.55 mm and height (h) 10.50 mm. The Lz design corresponds to a sealing lip with a spring and a specific configuration for lubricant retention. The 54.55 mm outer diameter indicates press-fit mounting in a machined housing, not in a cavity with wide tolerance. It is a standard replacement part within the radial shaft seal line.

Seals of this size are used on pump shafts, electric motors, gearboxes, conveyor rollers and power transmission equipment. They also appear in applications where oil leaks to the environment must be prevented and dust or water must be kept out of the bearing. In industrial plants, workshops and process lines, they are commonly found in equipment running at moderate speed with permanent lubrication. The choice of lip material depends on the fluid and the working temperature.

To install a radial shaft seal, check that the shaft has no burrs or wear on the sealing track and that the housing is clean and free of deformation. Lubricate the lip before inserting it and place the seal perpendicular to the shaft, without striking the spring. If the shaft shows a groove or wear, consider a nearby size or a repair sleeve. The final selection must take peripheral speed, pressure and lubricant type into account.
