The DBH 5036 is a radial shaft seal in the Kz design, built to hold lubricant in and keep dust, water and particles out of rotating assemblies. Its three key measurements are 52.40 mm at the shaft, 81.00 mm at the housing bore and 11.50 mm in height. Because it rubs continuously against the shaft, this seal is a wear item: once it starts weeping oil or running noisy, replacement is the practical fix.

Reading the code is straightforward. The 5036 designation ties back to the size set, and the three figures you need to confirm before ordering are shaft diameter (d) 52.40 mm, housing diameter (D) 81.00 mm and height (h) 11.50 mm. The Kz design refers to the combination of a sealing lip with a metal outer body, a construction that stays in contact with the rotating shaft and keeps the sealing edge loaded. The part presses into the housing bore and seals against the shaft as it turns.

You will run into seals like this one in gearboxes, pumps, electric motors, rollers and other power transmission equipment. The job is always the same: keep the oil or grease where it belongs and block anything abrasive from getting in, since dust and moisture shorten the life of bearings and gears. Process lines, conveyors and machinery that runs continuously are the usual places to find them.

Selection comes down to matching the bore and the shaft. Measure both, and check the chamfer and depth of the housing as well, because the Kz lip and body geometry is made for a particular seat; a different chamfer or depth may call for another variant. On installation, coat the lip with the same oil the equipment uses, keep the seal square as you press it in, and inspect the shaft for burrs or score marks that would chew up the lip.

If the original part carries a different designation but the dimensions line up, or you want to compare an equivalent from another brand, send us the code 5036 or the exact shaft and housing measurements. We can also advise when the lip configuration or quality grade of the original differs from what your application needs.
