A lip seal such as the DBH 8799 keeps lubricant where it belongs and keeps dust, water and particles out of rotating assemblies. With a 28.00 mm shaft, 38.00 mm housing bore and 7.00 mm height, it fits gearboxes, pumps and compact motors. MR Industrial Accessories supplies this brand and can help you match the seal to your equipment.
The code breaks down simply: 8799 identifies the item within the DBH line, and the Mx designation tells you the sealing element is a single lip with a spring. That spring keeps the lip pressed against the shaft, which is what holds oil or grease inside a machined cavity while the shaft turns. Because the lip is a wear item, this seal is one of the parts most often replaced during routine maintenance on permanently lubricated equipment.
In service, a seal in this size range shows up on gearbox input and output shafts, small centrifugal pumps, electric motors, spindles and transmission rollers. Its job in each case is the same: stop leaks at the shaft and shield the bearings from contamination. Light industrial machinery, machine tools and conveyor drives are common places to find it.
Installation is where most seal failures start. Confirm the shaft diameter falls within the recommended tolerance, and check that the surface it contacts is polished and free of burrs. The housing bore needs the right diameter and depth so the seal seats squarely instead of deforming. Coat the lip with the same oil or grease used in the unit before pressing it in, and avoid impacts during fitting. If the shaft is already worn, an auxiliary lip or a wear sleeve may be the better route.
For a quote, send the complete code plus the dimensions of the seal you are replacing. If the code is unreadable, the shaft diameter, housing diameter and height are enough for us to search. MR Industrial Accessories serves customers across the United States and in several Latin American countries, and the team can suggest equivalents and help you choose.
