For rotating equipment, the DBH 5488 radial shaft seal keeps lubricant where it belongs and keeps contamination out. It fits a 42 mm shaft in a 60 mm housing bore, with a 10 mm height, and it uses the Lx design. That designation points to a sealing lip backed by a spring, which is the arrangement you would expect on a turning shaft that runs with oil or grease.

Reading the code is straightforward. The 5488 identifies the item in the DBH line, and the three figures that follow describe the fit: shaft 42 mm, housing 60 mm, height 10 mm. The Lx design tells you the seal has a lip plus a spring. The lip rides against the shaft while the outer case presses into the bore, and together they close off the gap where lubricant would otherwise escape.

You will find this type of seal in gearboxes, centrifugal pumps, electric motors, compressors and power transmission assemblies. In each case the job is the same: hold the oil or grease inside and block dust, water and particles from getting in. Treat it as a wear part. Weeping oil, a visible film around the bearing area or unusual noise are the usual signs that it is time to replace it.

Before installing, confirm the shaft measures 42 mm and the bore 60 mm, with 10 mm of height available. The shaft surface should be clean and free of burrs, scratches and marks, since any roughness will work against the lip. Lightly lubricate the lip, then seat the seal with the lip facing the fluid it has to retain. If the equipment runs hot or at elevated speed, ask about the lip compound and the spring.
