The DBH 6641 radial shaft seal is a lip seal that prevents oil or grease leaks and blocks dust and moisture from entering equipment with a rotating shaft. Its dimensions of 22 mm shaft diameter, 40 mm housing bore and 6.50 mm height make it suitable for gearboxes, pumps, electric motors and similar mechanisms. MR Accesorios Industriales carries this brand and advises you so you choose the right seal for your equipment.

This item is a DBH 6641 radial shaft seal, identified by its numeric designation. Its main attributes are: shaft diameter (d) 22 mm, housing bore diameter (D) 40 mm and height (h) 6.50 mm. The Lz design corresponds to a configuration with a sealing lip and spring, intended to retain lubricant under continuous rotation conditions. The 6641 nomenclature allows you to locate it within the DBH line and request the exact replacement when needed.

Seals of this type are used in gearboxes, centrifugal pumps, electric motors, compressors and conveyor rollers. They also appear in agricultural and industrial equipment where shafts rotate inside a fixed housing and oil must be contained. In all these cases, the seal protects the bearings and prevents external contamination, extending the service life of the assembly.

To install a seal, check that the shaft and housing are clean, with no burrs or marks. The shaft surface must have suitable hardness and roughness; if it is worn, a wear sleeve should be used. The seal is pressed in with a suitable tool, without striking the lip, and is lubricated before assembly. Selection depends on speed, temperature and fluid type; if you have any doubts, consult us with your equipment data.

If you need an equivalent or a nearby size, the most practical approach is to send us the complete seal code, the shaft, housing and height dimensions, and a photo of the part. With that data we can look for alternatives in the same brand or in other lines we carry. We can also advise you if the space allows adapting a seal with a different height or design.
