The DBH 9100 is a radial shaft seal, the type of lip seal used to close the gap where a rotating shaft passes through a housing. It keeps oil, grease or water on the inside and blocks dust, chips and moisture from working their way in, which protects the bearings, bushings and gears behind it. Because the lip is a wear item, hardening or a marked shaft surface will eventually show up as leakage, and replacing the seal at that point is preferable to losing the whole assembly.
Sizing follows the standard three-value order: shaft 30 mm, housing bore 42 mm, height 6.00 mm. The Lx designation describes a single lip with an outer metal case, the common configuration for pressing into a cylindrical bore. Within the DBH line, 9100 identifies this particular size, so quoting that number is enough to receive the same seal or a cross-referenced equivalent.
You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment where a shaft turns inside a lubricated support. Agricultural machinery, conveyors and plant equipment exposed to dust or water are also common homes for it. The job is always the same: hold the lubricant in and keep contaminants out before they reach the bearing.
Before pressing a new seal in, inspect the shaft for burrs or wear at the contact zone and make sure the bore is clean and free of dents. Lubricate the lip, then seat the seal square to the housing without distorting it. When selecting a replacement, factor in shaft speed, operating temperature and the fluid being retained, since the wrong lip material will harden early and stop sealing even when the dimensions are correct.
Need a different size, another design or a cross-reference from a different brand? Send the 9100 number together with your shaft, housing and height measurements. A photo of the old seal, if the markings are still readable, also helps confirm the design and material.
MR Industrial Accessories supplies the DBH brand within its seals and oil seals range, alongside bearings, housings and power transmission components. Share the part number by WhatsApp or email and our team will quote the 9100 seal or a suitable equivalent for the size you require.

Frequently asked questions
- What are the dimensions of the DBH 9100 seal?
- Shaft 30 mm, housing 42 mm and height 6.00 mm, in an Lx single-lip design with a metal outer case.
- How can I confirm the 9100 seal matches the one on my equipment?
- Check the shaft diameter, the housing bore and the height. When all three line up and the design is single lip with an outer case, it drops in directly. If anything is unclear, send a photo of the old part along with caliper readings.
- What should I consider when picking a seal for my equipment?
- Shaft speed, working temperature and the fluid being retained decide the lip material. Shaft condition matters too, since a scratched or burred surface wears the lip early. With those details we can point you to the right option.
