The DBH 5866 is a radial shaft seal from the Lx series, built to keep lubricant in and contaminants out where a shaft turns inside a housing. Its three key measurements are shaft 34.93 mm, housing 57.15 mm and width 7.93 mm, which line up with common industrial bore sizes. Because it rubs directly against the shaft, it wears over time and should be swapped out once leaking or dirt entry shows up. MR Industrial Accessories supplies this brand and can help you confirm the right seal for your equipment.

This seal uses the Lx configuration: a single sealing lip backed by a spring, held in a metal case. The 5866 number is the manufacturer's size reference, so the same figure always points to the same three dimensions. Shaft 34.93 mm, housing 57.15 mm, width 7.93 mm. Treat it as a precision component; the lip must slide into place without nicks or folds, since any damage at installation shortens its working life.

You will find this seal in gearboxes, pumps, electric motors, transmission assemblies and general machinery where oil or grease must stay put around a rotating shaft. In dusty or wet areas it also keeps out grit and moisture. Industrial plants, agricultural equipment and continuous-process lines use it regularly. Changing it on schedule avoids lubricant loss and protects nearby bearings and gears from premature failure.

To choose the right replacement, measure the old seal's shaft seat, housing bore and width and compare them with the DBH 5866 figures. The Lx lip with spring suits moderate shaft speeds and low pressure. During fitting, coat the lip with the same lubricant used in the machine, press the seal in squarely to the shaft, and use a proper driver rather than a hammer. If the shaft is grooved or worn, consider a seal with a second lip. Clean the bore and shaft before assembly.

If 5866 is not available or you need a matching size, send the old seal's three measurements — shaft diameter, housing diameter and height — and we will check our seal and oil seal range for a suitable option. We can also tell you whether the Lx design fits your operating conditions. MR Industrial Accessories stocks this brand.
