The DBH 9742Pol radial shaft seal is a lip seal designed for rotating shafts. Its function is to retain lubricant inside the housing and block the entry of dust, water or particles. With dimensions of 12.70 mm shaft, 22.20 mm housing and 8.00 mm height, and an Mz design, it is used in equipment where space is limited and a reliable seal is required. MR Accesorios Industriales supplies this official brand and advises you on choosing the correct seal.

This item is a radial shaft seal from the DBH brand, identified by the designation 9742Pol. Its dimensions are 12.70 mm shaft diameter (d), 22.20 mm housing diameter (D) and 8.00 mm height (h). The Mz design corresponds to a configuration with a sealing lip and a spring that ensures constant contact on the shaft. It is intended for rotating shafts and fixed housings, and its compact profile allows installation in spaces where other seals do not fit.

Typical applications for a seal such as the 9742Pol include small electric motors, centrifugal pumps, gear reducers, gearboxes, compressors and transmission equipment. It is also used in agricultural machinery, pneumatic tools and lubrication systems. In all cases, its purpose is to prevent oil or grease leaks and protect bearings and bushings from the entry of contaminants, extending the service life of the assembly.

To install this seal, verify that the shaft and housing are clean, free of burrs and scratches. Lubricate the lip with the same oil or grease used in the equipment before inserting it. Pressure must be uniform, preferably with a tube or socket that bears on the outer diameter. If the shaft shows wear, consider a nearby size or a seal with an auxiliary lip. Selection depends on speed, temperature and lubricant type; consult us if you have doubts.

If you need a seal equivalent to the 9742Pol or a nearby size, send us the complete part number, the shaft and housing dimensions, and a photo of the old seal. With that data we can look for an alternative within the same brand or another line we supply. We can also offer the same Mz design in other dimensions if your equipment requires it. The idea is that you don't have equipment down due to a seal.
