Part number 6847 from DBH is a radial shaft seal, also called a lip seal, sized for a 75 mm shaft, a 100 mm housing bore and a 21.50 mm height. The Lz designation identifies how the lip and the rest of the seal are built, which is what determines how it behaves once installed. MR Industrial Accessories LLC supplies this brand and helps buyers confirm the size and the design before they order.
Reading the code is the first step. The 6847 number identifies the item itself, while the three figures that follow describe the space it has to fill: shaft 75 mm, housing 100 mm, height 21.50 mm. In a seal, the Lz design tells you which construction you are getting, so it belongs in the same check as the measurements. A seal only works if the three dimensions match the equipment and the design suits the service.
These seals sit in gearboxes, centrifugal pumps, electric motors, rollers and drive shafts, wherever a rotating shaft passes through a housing. Two jobs happen at once: oil or grease stays where it belongs, and dust, water and particles stay outside. In plants where vibration, heat or shaft speed are moderate, choosing the right seal protects the bearings and keeps unplanned downtime down.
Installation rewards care. Confirm the 75 mm shaft and the 100 mm bore, and make sure there is 21.50 mm of room for the height. The shaft surface should be smooth, free of burrs and not worn past its limit. Apply lubricant to the lip, seat the seal square to the shaft and press it in without hitting the lip directly. Where dirt is heavy, a version with an extra dust lip is worth considering, and the lip compound and spring also influence how the seal performs.

Frequently asked questions
- What size is the DBH 6847 seal?
- It is built for a 75 mm shaft, a 100 mm housing bore and a 21.50 mm height. Check those three figures on the equipment before ordering. If you are unsure about any of them, ask and we will help you verify.
- Where is this seal used?
- Gearboxes, pumps, motors and rotating shafts are typical applications, since the seal keeps lubricant inside and contamination outside. Moderate speed and temperature conditions suit it. Tell us if your equipment runs in heavy dirt or at high speed and we will point you to a better option.
- How do I ask for an equivalent seal?
- Send part number 6847 by WhatsApp together with the shaft, bore and height dimensions and a photo of the original seal. That is enough for us to locate the closest equivalent. We can also explain the Lz design and the alternatives.
