The DBH 5524 is a radial shaft seal built for rotating shafts. It keeps lubricant where it belongs and blocks dust, water and other contaminants from reaching the bearing cavity. The published size is 34 mm shaft, 52 mm housing and 8 mm height, with an Mz profile. MR Industrial Accessories supplies this seal and can help you confirm it fits your equipment.

This seal carries the DBH brand and the code 5524. Reading the size as shaft 34 mm, housing 52 mm and height 8.00 mm tells you where it belongs: pressed into a housing bore, with the lip running against the shaft. The Mz designation refers to a specific body and lip geometry inside the DBH range, so the profile matters as much as the three dimensions.

You will find seals like this one in gearboxes, pumps, electric motors and transmission shafts, as well as in equipment running near dust or moisture. In those spots the seal protects bearings and gears from premature wear. It is a wear part: the lip eventually hardens or scores the shaft, and lubricant starts to escape.

Before ordering, check that the shaft and housing match the published figures. The 8.00 mm height has to sit in the cavity without being crushed. If the old seal has a different profile than Mz, compare the cross-section before installing. When fitting, coat the lip with lubricant, keep the seal square, and inspect the shaft for burrs or marks that could cut the lip.

For a quote on an equivalent, send the code 5524 plus shaft, housing and height measurements. A photo of the old seal or the equipment drawing also helps. We compare that information against the options we carry and propose compatible choices, so the more detail you send, the closer the match.
