The DBH 8457/85 is a radial shaft seal that keeps oil or grease contained where a shaft turns inside a housing. It measures 26 mm at the shaft, 37 mm at the housing bore and 7 mm in height, and it uses the Lx design. You press it into covers, gearboxes or pumps to hold lubricant in and keep dust or water out. Like any seal, it wears and should be changed once leakage starts.
This is a DBH radial shaft seal with the code 8457/85. The dimensions are shaft 26.00 mm, housing 37.00 mm, height 7.00 mm. The Lx design means a single lip with a spring, with the lip oriented toward the fluid being retained. The elastomer lip runs against the shaft, while the metal outer case holds the seal in the housing bore.
You will find this seal in equipment with rotating shafts that must retain lubricant: gearboxes, centrifugal pumps, electric motors, mixers, drive shafts and rollers. It also suits situations where oil retention is combined with keeping out dust, chips or process water. It is a typical item in preventive maintenance and in repairs of machines that have seen years of service.
When selecting the seal, confirm the three dimensions against the shaft and housing: 26 mm shaft, 37 mm housing, 7 mm height. Inspect the shaft surface; a groove or wear will prevent the new lip from sealing, so you may need a replacement shaft or a seal with the lip positioned differently. During installation, coat the lip with the same grease or oil used in the equipment, insert it squarely and tap only on the metal case, never on the elastomer.
If the code 8457/85 does not match what is on your equipment, send the dimensions of the old seal (shaft diameter, outer diameter and height) along with a photo. With that information we can look for an equivalent in DBH or in another brand we carry. We can also confirm whether the Lx design fits your application or if a different lip type would work better.

Frequently asked questions
- What are the dimensions of the DBH 8457/85 oil seal?
- Shaft diameter 26.00 mm, housing diameter 37.00 mm and height 7.00 mm. The design is Lx, single lip with spring. Compare these with your shaft and housing before installing.
- How can I check if the 8457/85 oil seal fits my equipment?
- Measure the shaft where the lip runs, the housing bore and the height of the old seal. If they match 26, 37 and 7 mm, the seal is compatible.
- What does the Lx design indicate on this oil seal?
- Lx indicates a single-lip seal with spring, meant to retain lubricant on a rotating shaft. The lip faces the fluid side. If your application involves high pressure or heavy dirt, ask us whether another design is better.
