The DBH 8429Vit is a radial shaft seal built for rotating shaft applications. It keeps oil or grease where it belongs and blocks dust, water and particles from working their way in. The unit fits a 90 mm shaft, a 110 mm housing bore and an 11.00 mm height, and it uses the Lx-R lip and spring configuration. Because it is a wear part, it belongs on your inspection checklist so leaks do not develop unnoticed.
Reading the size is straightforward: shaft 90 mm, housing 110 mm, width 11.00 mm. The Lx-R designation tells you the seal has a sealing lip backed by a spring, which is the setup used on rotating shafts. The part is pressed into the housing and the lip rides on the shaft. Match all three measurements against your equipment before you order, since a small deviation is enough to keep the seal from seating correctly.
You will find seals of this type in gearboxes, pumps, electric motors, rollers and other transmission equipment. Their job is to hold lubricant in and keep contaminants out, which protects bearings and gears downstream. Where dust or moisture is present and the shaft spins, the lip needs steady, even contact. On equipment that runs with vibration or misalignment, inspect the shaft and housing condition before you install a replacement.
Selection comes down to three values: shaft diameter, housing bore and height. The Lx-R code describes how the lip is built and oriented. When installing, coat the lip with the same lubricant the equipment uses, keep the seal square to the shaft, and drive it in with a tube or press that contacts the outer diameter only, never the lip. A shaft with burrs or a worn contact zone will shorten seal life, so check that area first.
If you need an alternative for code 8429Vit, measure the shaft, the housing bore and the height, and send those figures along with a photo of the old seal. With that information the team can look at the DBH line or another compatible option, and can also tell you whether a different lip design would suit your application better. Quotes are handled by WhatsApp or email using the part number and the quantity you need.

Frequently asked questions
- What size is the DBH 8429Vit seal?
- Shaft 90 mm, housing 110 mm, height 11.00 mm, with an Lx-R design. Confirm these three figures on your equipment before ordering, as a small difference will prevent correct installation.
- How can I confirm this seal fits my equipment?
- Measure the shaft where the lip runs, the housing bore and the height of the seal you are removing. If they read 90, 110 and 11.00 mm and the lip style is similar, the part matches. Send us the measurements if anything is unclear.
- What does the Lx-R design indicate?
- It identifies a radial shaft seal with a sealing lip and spring, made for rotating shafts and lubricant retention. If your equipment calls for a different lip orientation, ask us about an alternative.
