The DBH 9511/85 radial shaft seal is a lip seal designed for 28 mm rotating shafts, with a 40 mm housing bore and a 6 mm height. Its function is to retain lubricant inside the assembly and block the entry of dust, water or particles that could damage bearings and bushings. It is press-fitted into the housing and runs on the shaft with a flexible lip that maintains dynamic contact. It is a key part in gearboxes, pumps and electric motors, where reliable sealing extends the service life of the internal components.

This item is a seal of Lx design, with the following dimensions: shaft diameter 28 mm, housing bore 40 mm and height 6.00 mm. The Lx design corresponds to a seal with a single sealing lip and metal case, suitable for applications where axial space is limited. The 9511/85 nomenclature identifies the geometry and the lip material, which is usually nitrile rubber (NBR) to resist mineral oils and greases. DBH is a brand that MR carries, so you can ask us about this particular size.

Typical applications for this seal include gearboxes, centrifugal pumps, electric motors, compressors and machine tool spindles. In all these machines, the seal prevents oil leaks and the entry of contaminants, which reduces wear on bearings and gears. It is also used in speed reducers and belt or chain drive systems, where the shaft rotates at moderate speeds and reliable, low-maintenance sealing is required.

To install the seal correctly, check that the shaft surface is polished and free of burrs, with adequate hardness so as not to damage the lip. Lubricate the lip with the same oil used in the machine before inserting it, and fit the seal with a press or installation tube that bears on the outer diameter, never on the lip. Make sure the housing is clean and free of burrs. If the shaft shows wear, consider using a wear sleeve or a nearby size. Selection depends on peripheral speed, temperature and the fluid to be retained.
