Part number 8279 is a DBH radial shaft seal, a lip seal that keeps oil or grease where it belongs in rotating assemblies. Its sealing point is a 52 mm shaft running inside a 72 mm housing bore, and the profile measures 7.50/16.00 mm in height with design A 056. By closing the gap between the rotating shaft and the fixed housing, it holds lubricant in and keeps dust, water and grit out, which is what protects the bearings and bushings nearby from premature wear.

Read the code first: 8279 identifies the DBH seal, and the size string 52x72x7.50/16 tells you shaft, housing and height in that order. Design A 056 describes how the lip and outer body are formed. The 7.50/16.00 mm figure points to a two-part profile, a lip section plus a stepped body, so the housing depth has to be respected for the lip to sit correctly.

Typical locations include gearboxes, pumps, electric motors, conveyor rollers and other power transmission equipment, as well as machine tools, agitators and pumping systems. Whatever the machine, the job is the same: hold the lubricant at the shaft exit and block contaminants before they reach the bearings or bushings.

Before fitting, confirm the shaft and bore are clean and free of burrs, nicks or pull marks. Coat the lip with the grease or oil the equipment already uses, then seat the seal squarely. If the shaft surface is worn, the lip may not run true; a seal with an auxiliary lip or a repair sleeve is worth considering.
