The DBH 6456 radial shaft seal is a lip seal designed to close off lubricant passage and prevent the entry of contaminants in rotating equipment. With dimensions of 57.15 mm shaft, 85.63 mm housing and 17.85 mm height, and an Mx design, it adapts to assemblies where axial space is limited. It is a common replacement part in pumps, electric motors, gear reducers and gearboxes. MR Accesorios Industriales carries this official brand and advises you so you request the right seal.

This item is a radial shaft seal from the DBH brand, identified by the code 6456. Its dimensions are 57.15 mm shaft diameter, 85.63 mm housing diameter and 17.85 mm total height. The Mx design corresponds to a configuration with a sealing lip and metal case, designed to retain oil or grease on rotating shafts. The lip runs on the shaft and the outer case seats under pressure in the housing, creating a tight seal that protects the bearings and prevents leaks.

Typical applications for a seal like the DBH 6456 include centrifugal pumps, electric motors, speed reducers, gearboxes and transmission equipment. In all these cases, the seal serves to keep the lubricant inside the assembly and block dust, water or particles that could accelerate bearing wear. It is a wear part that should be replaced when oil leaks or abnormal shaft noise appear.

To correctly mount this seal, verify that the shaft has no burrs or marks that could damage the lip, and lubricate the lip with the same oil or grease used in the equipment before inserting it. The housing must be clean and free of deformation. When selecting a replacement seal, take into account not only the dimensions but also the type of fluid, the working temperature and the shaft speed. The Mx design is suitable for general applications, but if the equipment operates under severe conditions, ask us about more resistant variants.
