For rotating shafts that need a reliable barrier between lubricant and the outside environment, the DBH 5424 radial shaft seal is a compact, single-lip solution. It measures 31.00 mm at the shaft, 47.00 mm at the housing and 7.00 mm in height, and carries the Lz designation. MR Industrial Accessories supplies this brand and helps maintenance teams match the seal to the shaft, housing bore and lubricant in use.

The 5424 belongs to the DBH line of radial shaft seals. Its Lz configuration means a single sealing lip with a spring, intended for rotating shafts under permanent lubrication. The elastomer lip runs against the shaft surface while the metal outer case holds the seal firmly in the housing bore. As a standard replacement item in the seals and oil seals category, it is easy to source by code and dimensions alone.

Where a 31 x 47 x 7 mm seal fits, you will often find gearboxes, centrifugal pumps, electric motors, compressors and belt or chain drives. Machine tools, industrial washing equipment and low-pressure hydraulic systems also use this size. In each case the seal keeps lubricant inside the assembly and blocks dust and water from entering, which helps protect bearings and gears from premature wear.

Before installation, confirm the shaft measures 31.00 mm and the housing bore 47.00 mm, with enough housing width for the 7.00 mm height. The shaft surface should be smooth and free of burrs. Lubricate the lip, then press the seal in with a tube that contacts only the outer edge. If the equipment sees high vibration or temperature, ask about alternative materials and designs; speed, pressure and the fluid being retained will determine the final choice.

When you need an equivalent from another brand, send the code 5424 together with the shaft, housing and height dimensions. We can also locate an Lz design seal from another manufacturer we supply. The more details you include—lubricant type, operating temperature and RPM—the more precise the match will be. A drawing is not required; the code and dimensions are enough to begin.
