The DBH 5421 is a radial shaft seal in the Lx design, sized for a 20.00 mm shaft, a 47.00 mm housing bore and a 10.00 mm width. It keeps lubricant in and contaminants out on rotating shafts in gearboxes, pumps, motors and similar power transmission equipment. MR Industrial Accessories supplies this brand and helps you match the seal to your application.

The code 5421 identifies a DBH radial shaft seal. Its three key dimensions are shaft 20.00 mm, housing 47.00 mm and height 10.00 mm. The Lx design uses a single sealing lip with a spring, which is intended for rotating shafts that run with lubrication. The lip elastomer and the metal case work together to hold the seal in place and maintain contact with the shaft.

You will find seals like the DBH 5421 in gearboxes, centrifugal pumps, electric motors, conveyor rollers and other power transmission assemblies. They do two jobs: stop oil or grease from escaping and keep dust, water and particles from getting in. In industrial, food and process plants, that protection helps bearings last and keeps the assembly running as intended.

When installing a radial shaft seal, inspect the shaft for burrs or wear and make sure the housing bore is clean and free of dents. Lubricate the lip before fitting, then press the seal in with a proper tool. Do not strike the lip. The right choice depends on shaft speed, temperature and the lubricant in use. If the shaft track is worn, a seal with an auxiliary lip may be worth considering.
