Part number 1012 from DBH is a radial shaft seal built to hold lubricant in place and keep dust and dirt out of rotating assemblies. Its three key measurements are a 76.20 mm shaft diameter, a 107.92 mm housing bore and an 11.12 mm height. The Kz designation means the seal carries both a sealing lip and a dust lip, which suits equipment exposed to moderate amounts of dirt. Pumps, gearboxes and transmissions are the usual places this seal shows up, and it is often replaced during preventive maintenance.

Reading the number is straightforward: 1012 identifies the size, and the dimensions that go with it are shaft 76.20 mm, housing 107.92 mm and height 11.12 mm. The Kz configuration pairs a main sealing lip with a secondary dust lip, so the elastomer body and its internal spring keep the sealing edge in contact with the shaft while the outer lip blocks particles. That combination is what makes it a practical choice where rotating shafts need a dependable barrier.

You will find this seal in centrifugal pumps, gearboxes, transmission shafts and process equipment. In each case it does two jobs at once: it stops oil or grease from escaping and it keeps grit away from the bearings. Since these are parts that wear, they are routinely swapped out on production lines and pumping equipment as part of a scheduled maintenance program.

Installation is where most seal failures start. Confirm the shaft and housing bore are clean and free of burrs before anything goes in. Coat the lip with the same oil or grease the equipment runs on. Press the seal in evenly across the outer diameter rather than striking the lip, and if the shaft surface is worn, a repair sleeve is worth considering. Speed, temperature and the fluid being sealed all influence which seal is right for the job.
