The DBH 5230 is a radial shaft seal that keeps lubricant in and contaminants out where a shaft turns inside a fixed housing. Its three key measurements are a 50.00 mm shaft, a 65.00 mm housing bore and a 10.00 mm width. MR Industrial Accessories supplies this seal for gearboxes, pumps and other power transmission equipment, and can help you confirm the right choice for your application.

The designation 5230 follows the usual radial shaft seal code: 50.00 mm shaft diameter (d), 65.00 mm housing diameter (D) and 10.00 mm height (h). The Lz version has one sealing lip with a spring, so it holds lubricant in and keeps dust out under normal operating conditions. The elastomer body works with the internal spring to maintain contact on the rotating shaft.

Typical installations include gearboxes, centrifugal pumps, electric motors, conveyor rollers and power transmission assemblies. You will find it wherever a rotating shaft passes through a stationary housing and oil loss or particle entry has to be avoided. It also serves as a secondary seal next to bearings, helping protect the lubricant and the surrounding components.

During installation, confirm the shaft surface is hard enough and smooth enough, with no burrs or scratches that could cut the lip. Apply lubricant to the seal before fitting it, and drive it in with a tube that presses on the outer diameter only, never on the lip. The housing bore should be clean and free of dents. If the shaft is already worn, an auxiliary lip version may be worth considering.

For an equivalent or another size, send the complete part number along with the shaft, housing and height dimensions, plus the fluid being sealed. That information lets us search alternatives in other brands or lip configurations. We can also help you select a lip design that suits the operating speed and temperature.
