The DBH 5634 radial shaft seal is a lip seal designed to keep lubricant in and contaminants out of rotating assemblies. With dimensions of 30 mm shaft, 45 mm housing and 8 mm height, and an Mz design, it is fitted in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales supplies this brand and advises you so you choose the right seal for your application.

This item is a radial shaft seal from the DBH line, identified by part number 5634. Its nominal dimensions are 30.00 mm shaft diameter (d), 45.00 mm housing diameter (D) and 8.00 mm height (h). The Mz design corresponds to a configuration with a sealing lip and metal case, suitable for retaining oil or grease on rotating shafts. It is a standard replacement part within the seals and oil seals category, designed to be press-fitted into the housing with its lip resting on the shaft.

Typical applications for a seal of these dimensions include gearboxes, speed reducers, centrifugal pumps, electric motors, compressors and belt or chain drive equipment. In all cases it serves to confine lubricant inside the assembly and block dust, water or particles that could damage bearings and gears. It is also used in machine tools, industrial washing equipment and hydraulic systems where a reliable dynamic seal is required.

To select and fit this seal correctly, check that the shaft diameter is 30 mm and the housing is 45 mm, with a housing width compatible with the 8 mm height. The shaft surface must be ground and free of burrs; the housing must be clean and have a suitable entry chamfer. Lubricate the lip before fitting and avoid striking it during installation. If the equipment runs at high speed or under high pressure, consult MR to evaluate the Mz design or another variant.

If you need an equivalent seal or a nearby size, the most practical approach is to send us part number 5634 or the current dimensions of your shaft, housing and height. With that data we can look for an alternative within the same DBH line or from other brands we supply. We can also advise you if the mounting space allows a seal with an additional lip, double lip or a different material depending on the fluid and working temperature.
