The DBH 8399Vit is a radial shaft seal built to keep lubricant where it belongs and keep dust and water out of rotating assemblies. Left unchecked, those contaminants shorten the life of bearings and bushings. The seal fits a 38 mm shaft, a 50 mm housing bore and a 6.00 mm height, and it uses the Lx-R lip configuration. MR Industrial Accessories supplies it as part of its seals and shaft seal range.

Reading the reference is simple. DBH is the brand, 8399Vit is the item code, and the numbers in the size string follow the usual order: shaft 38 mm, housing 50 mm, height 6.00 mm. The Lx-R designation points to a lip with a spring, so the sealing edge stays in contact with the shaft as it turns. The outer diameter presses into the housing, while the lip works against the moving shaft surface.

You will find seals of this type in gearboxes, pumps, electric motors, rollers and power transmission equipment, as well as in machine tools, conveyors and lubrication systems. Any assembly with a rotating shaft that needs to be separated from the surrounding environment is a candidate. Before confirming a replacement, check that the operating temperature, shaft speed and lubricant are compatible with the lip and body material, using the manufacturer's technical data sheet.

Installation has a direct effect on how long the seal lasts. Keep the bore and shaft clean, confirm the shaft has no scratches or wear marks and check that the housing is concentric. Lubricate the lip before pressing the seal in, and drive it with a tube or socket that contacts the outer diameter so the force stays even. If the shaft shows a worn track, an offset lip or a repair sleeve is worth considering.

When you need an alternative, send the code 8399Vit or the three dimensions and we can search our DBH seal line or other brands we supply. We can also point you to the design that suits your application. The measurements still have to match the housing and the shaft for the seal to work.
