The DBH 8210 radial shaft seal is a lip seal that is mounted in a component housing and seals against the rotating shaft to retain lubricant and stop the ingress of dust, water or particles. Its compact format of 17 mm shaft by 23 mm housing and 4 mm height makes it suitable for small gearboxes, pumps and motors where axial space is limited. MR Accesorios Industriales sells it as part of its line of seals and oil seals for maintenance and replacement.

The DBH 8210 is an Lt design oil seal: single lip with spring, intended for rotating shafts with permanent lubrication. Its dimensions are 17 mm shaft diameter, 23 mm housing diameter and 4.00 mm height. The sealing lip works on the shaft and the outer diameter fits by interference in the housing. The 8210 designation identifies the dimensional combination within the DBH line, and the Lt design defines the lip profile and its mounting geometry.

It is used in equipment where oil or grease must be contained in a small space: small electric motors, gear reducers, centrifugal pumps, compressors, machine tools and light drives. It also appears in industrial maintenance applications where a worn oil seal is replaced with one of the same size. As it is a wear component, it is advisable to check it when lubricant leaks, noise or ingress of contaminants appear in the bearing area.

To mount it, check that the shaft is clean, without burrs or marks, and that the sealing surface does not have deep wear. Lubricate the lip before inserting it and place the oil seal with a tube or shim that rests on the outer diameter, never on the lip. If the housing has a shoulder or radius, respect the seating depth. The 4.00 mm height requires a housing with enough space for the oil seal to sit flush or slightly recessed.

If you cannot find the 8210 part number or you need a nearby size, send us the shaft, housing and height dimensions, plus a photo of the old oil seal or the housing. With that data we look for the equivalent in the DBH line or in another brand we carry. We can also advise you if the Lt design is not suitable for your application and a different lip profile is needed.
