The DBH 5774 radial shaft seal is a lip seal mounted between a rotating shaft and a stationary housing to retain lubricant and block the entry of dust, water or particles. With a 33 mm shaft diameter, 56 mm housing diameter and 12 mm height, and Mz design, it is a common size in pumps, electric motors, gearboxes and power transmission equipment. MR Accesorios Industriales carries this brand and helps you confirm the size before requesting a quote.

This item is a DBH 5774 radial shaft seal, identified by its designation 5774. Its dimensions are 33 mm shaft diameter (d), 56 mm housing diameter (D) and 12.00 mm height (h). The indicated design is Mz, a lip profile with sealing characteristics suited to rotating shafts. It is a single lip seal, designed to work with lubricant on the inner side and the environment on the outer side. DBH is a brand that MR carries.

Typical applications for a seal of this size are found in equipment where a shaft rotates inside a housing: centrifugal pumps, electric motors, gear reducers, gearboxes, mixers and machine tools. It is also used in rollers, conveyors and process equipment where the goal is to contain oil or grease and keep dirt out. In every case, verify that the seal is compatible with the lubricant, the operating temperature and the shaft speed.

For proper installation, check that the shaft has no burrs or wear in the lip area and that the housing is clean and free of dents. Lubricate the lip before inserting it and set the seal perpendicular to the shaft, using a tube or press that bears on the outer diameter, never on the lip. If the shaft shows a marked groove, consider a seal with an offset lip or a wear sleeve. Selection depends on the type of lubricant, the temperature and the peripheral speed.

If you cannot find part number 5774 or need a nearby size, send us the dimensions of the old seal: shaft diameter, housing diameter and height, plus a photo of the part and the housing. With that data we look for the equivalent in DBH or another brand we carry. If the seal has no legible part number, measure the shaft and housing with a caliper, and note the lip type and material. That way we can offer you the closest option without guessing.
