Part number 8858 from DBH is a radial shaft seal built around a 6 mm shaft. It seats in a 16 mm housing bore and measures 6.00 mm in height. Its job on a rotating shaft is twofold: hold the lubricant where it belongs and keep dust, water and other particles out of the assembly. You will find it in gearboxes, pumps, electric motors and small reducers where there is little room along the shaft.

The 8858 carries the Lx designation, which means a single lip with a spring, made for lubricated rotating shafts. Reading the code is straightforward once you know the layout: shaft size first, housing bore second, height last. That makes it easy to line this seal up against other options in the same category before you commit to a replacement.

Typical installations are compact ones running at moderate speed, such as small centrifugal pumps, low-power motors, speed reducers, transmission boxes, spindles and drive mechanisms. Machine tools, lab equipment and automation devices also use this size when oil or grease has to stay contained and outside contamination has to stay out.

For selection, confirm three values against the application: shaft 6 mm, housing bore 16 mm, height 6.00 mm. The Lx lip tolerates a small amount of misalignment, and it works best on a shaft with a fine finish and suitable hardness. When installing, coat the lip with lubricant, keep the spring facing the fluid being retained, and press it in without hitting the lip. A worn shaft can be brought back with a repair sleeve.

Replacing a seal is often easier by dimensions than by brand. If you send part number 8858 or the measurements of the seal you are removing, the team can compare it with other series in the same category and point you to the closest match. Seals from different brands and in different configurations are also available for special cases.

Quotes are handled by WhatsApp or email. Include the part number and dimensions, and you will get a prompt reply with the options that fit your equipment, plus help choosing between them if more than one works.
