The DBH 8866 is a radial shaft seal built around a 7 mm shaft, a 22 mm housing bore and a 7 mm height, supplied in the Lx design. It keeps lubricant where it belongs and keeps dust, water and other particles out of assemblies that turn on a shaft. MR supplies this brand and helps you match the seal to the job.

The designation 8866 identifies this radial shaft seal. Read the dimensions in this order: shaft 7.00 mm, housing bore 22.00 mm, height 7.00 mm. The Lx design means one sealing lip with a spring, a configuration made for rotating shafts. DBH is a brand MR supplies, and each seal arrives with its own identification and traceability.

You will find seals like this one in gearboxes, pumps, electric motors, compressors and power transmission equipment. They do two jobs at once: they hold oil or grease inside the assembly and they stop outside contaminants from working their way in. On a 7 mm shaft, the seal usually shows up in small mechanisms, instrumentation, lab equipment or special machines where radial space is tight.

Choosing the right seal comes down to three measurements: shaft diameter, housing bore and available height. Speed, operating temperature and the lubricant in use also play a role. The Lx design with its spring works well on rotating shafts that see permanent lubrication. If the shaft surface is worn or rough, a repair sleeve or a different size may be the better route.
