The DBH 5133Sil radial shaft seal is a lip seal that mounts on a 20 mm shaft and seals against a 30 mm housing, with a 7 mm height. Its function is to retain lubricant inside the assembly and stop the ingress of dust, water or particles. It is used in gearboxes, pumps, electric motors and transmission equipment, where the shaft rotates continuously and a reliable, low-maintenance barrier is required.

This item is a seal from the DBH line, identified as 5133Sil. Its dimensions are 20 mm shaft, 30 mm housing and 7 mm height, with Lz design. The Lz design corresponds to a seal with a sealing lip and spring, intended for rotating shafts with lubrication. The lip elastomer runs on the shaft surface and the metal case fits into the housing. It is a wear part: over time the lip hardens or becomes marked and starts to leak.

Typical applications for a 20 x 30 x 7 mm seal appear in equipment with small-diameter shafts and moderate speeds: electric motors, centrifugal pumps, gear reducers, compressors, machine tools and belt or chain drives. It is also found in agricultural implements and in process equipment where two environments must be separated: one with oil or grease and another exposed to the environment. In all cases, the seal prevents leaks and protects the bearings.

To install it properly, verify that the shaft has no burrs or wear in the contact area and that the housing is clean and free of dents. Lubricate the lip before inserting it and seat the part straight, without tilting it, using a tube or spacer that rests on the outer edge. If the shaft has a groove or a shoulder, the lip must be on the lubricant side. Selection depends on speed, temperature and fluid; if in doubt, consult us.
