The DBH 9351 radial shaft seal is a lip seal mounted in a machine housing to retain lubricant and block the entry of dust, water or particles. With a 12 mm shaft, 20 mm housing and 5.00 mm height, this Ls design covers small-diameter rotating shafts in pumps, electric motors, gear reducers and power transmission equipment. MR Accesorios Industriales sells the DBH brand within its line of seals and oil seals.

The DBH 9351 is a single-lip radial shaft seal. Its dimensions are 12.00 mm shaft diameter (d), 20.00 mm housing diameter (D) and 5.00 mm height (h). The Ls design corresponds to a seal with a sealing lip and metal body, intended for rotating shafts with lubrication. The 9351 designation identifies this specific size within the DBH line, so it is worth verifying those three values before replacing a part.

It is used in equipment where the shaft rotates inside a housing and the oil or grease must be separated from the environment. It appears in small centrifugal pumps, electric motors, gear reducers, gearboxes, compressors and machine tools. Also in power transmission applications where the seal prevents leaks and protects the bearings from the entry of contaminants. It is a wear part: when the lip hardens or the shaft becomes marked, it starts to leak.

To install it, clean the housing and the shaft, check that there are no burrs or splines that could cut the lip, and lubricate the seal before seating it. It is installed with a press or a support tube, never by striking the lip. Check that the shaft does not have wear greater than the seal tolerates and that the contact surface is polished. If the old seal leaked, measure the shaft and the housing with a caliper before requesting the replacement.
