The DBH 5039 is a radial shaft seal built to hold lubricant in and keep contaminants out where a shaft turns inside a housing. Its three key measurements are a 40.10 mm shaft diameter, a 61.16 mm bore and a 13.49 mm height, and it comes in the Kz design. Pressed into the housing and running against the shaft, it forms the dynamic barrier that shields bearings, bushings and gears.

Reading the code is the fastest way to match a seal to a machine. The number 5039 identifies this size in the DBH line, and the three figures that follow describe the fit: 40.10 mm across the shaft, 61.16 mm for the housing bore and 13.49 mm in height. The Kz designation tells you the seal carries a lip with a spring, so contact on the shaft stays constant as it rotates. Use these values to cross-check the shaft and bore tolerances before you order.

Where you will run into a seal like this: gearboxes, pumps, electric motors, reducers and other power transmission equipment. In each case the job is the same, keeping oil or grease where it belongs and shutting out dust, water and particles that would otherwise chew up bearings and gears. Industrial machinery, farm equipment and vehicles all rely on this kind of sealing to hold lubrication in place and keep components running.

Installation deserves attention. Check that the shaft surface is hard and smooth enough for the lip to ride on, and that the housing bore is clean with no burrs or nicks. Put a light film of lubricant on the lip, then seat the seal with a driver that pushes evenly on the outer diameter instead of hammering on the lip. When you pick a seal, factor in shaft speed, working temperature and the fluid being sealed. A worn shaft can often be brought back with a repair sleeve.
