The DBH 1242 is a radial shaft seal that keeps lubricant in and contaminants out of rotating shaft assemblies. It fits a 72 mm housing bore and has a 9 mm height, following the A 378 design. You will find it in gearboxes, pumps and motors, where it helps protect bearings and prevent leaks. MR Industrial Accessories supplies this seal as part of its line of seals and oil seals for industrial maintenance.

This radial shaft seal comes from the DBH brand and is identified by part number 1242. Per the data sheet, it uses the A 378 design with a 72 mm housing diameter and a 9 mm height. The construction is a lip seal with a metal case and elastomer, intended for rotating shafts.

Typical installations include gearboxes, centrifugal pumps, electric motors, mixers and transmissions—any rotating equipment that needs to hold oil or grease. In dusty or wet areas, the exclusion lip helps block particles from entering. By keeping lubricant where it belongs and shielding bearings, the seal supports the service life of the assembly.

When choosing a seal, confirm the shaft diameter, housing bore and height. Operating speed, temperature and the lubricant in use all affect which lip material works best. At installation, apply lubricant to the lip, keep the housing clean and free of nicks, and avoid cutting the lip on burrs. These steps go a long way toward preventing early leaks and failures.

If you need a different size or a replacement, send us part number 1242 or the dimensions of your current seal. We can also search for alternatives in other brands or series when you provide the shaft, housing and height dimensions. MR Industrial Accessories helps you identify the right part.
