The DBH 5653 radial shaft seal is a lip seal designed to stop lubricant from escaping and prevent contaminants from entering rotating shafts. With dimensions of 65 mm shaft, 85 mm housing and 12 mm height, and an Mz design, it is press-fitted into the housing and runs on the shaft with an oil film that ensures sealing and low friction. It is a key part in gearboxes, pumps and motors, where reliable sealing extends the service life of bearings and gears.

This DBH 5653 oil seal has a designation that matches its dimensions: 65.00 mm shaft diameter (d), 85.00 mm housing diameter (D) and 12.00 mm height (h). The Mz design indicates a specific construction within the DBH line, intended for applications with moderate pressure and speed requirements. The sealing lip, made from elastomers resistant to oils and greases, ensures uniform contact on the shaft and compensates for minor misalignments.

Radial shaft seals such as the DBH 5653 are used in a wide variety of industrial equipment: gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain drives. Their main function is to retain lubricant inside the assembly and block dust, water or particles that could damage the bearings. In environments with vibration or moderate temperatures, a properly selected seal reduces maintenance downtime and oil loss.

To install the seal correctly, check that the shaft has no burrs or excessive wear in the contact area; a scratched shaft accelerates lip failure. Lubricate the lip with the same grease or oil used in the equipment before inserting it, and place the seal perpendicular to the shaft using a support tube that rests on the outer diameter. If the housing has a chamfer, use it to avoid damaging the seal. Selection must consider peripheral speed, operating temperature and the chemical compatibility of the elastomer with the fluid to be retained.

If you need a nearby size or an equivalent from another brand, the most practical approach is to send us the complete seal code (in this case, 5653) along with the shaft, housing and height dimensions. With that data we can search our line of seals and oil seals for the item that best fits, or suggest an alternative with the same Mz design. We can also advise you if the mounting space allows height variants or if a seal with an additional lip is preferable.
