When a gearbox, pump or motor starts weeping oil around the shaft, the DBH 1282 radial shaft seal is the part that usually needs attention. It is a lip seal: the outside of the metal body presses into the housing bore, while the sealing lip rides on the rotating shaft. The designation tells you the fit — 55 mm shaft, 102 mm housing, 8.00/10.00 mm height — and design A 293 describes the lip-and-metal-case configuration.
Reading the number is the fastest way to check a replacement. The first figure is the shaft diameter the lip contacts, the second is the bore it presses into, and the third is the height. Here that means 55 mm on the shaft, 102 mm in the housing and a height of 8.00/10.00 mm. The two height values reflect the profile: depending on how the seal seats, the effective height can fall within that range. Design A 293 is the reference for this lip and metal body arrangement.
You will find this seal in gearboxes, centrifugal pumps, electric motors, rollers and other power transmission assemblies. Its job is simple to state and important in practice: hold oil or grease in, and keep dust, water and particles out. The lip creates a dynamic barrier against the rotating shaft, so it also suits locations exposed to splashing or airborne dirt.
Installation decides how long a seal lasts. Inspect the shaft for burrs, scratches or wear marks that could cut the lip, and make sure the housing bore is clean and not deformed. Put a film of lubricant on the lip before pressing the seal in, keep it square to the shaft, and apply force evenly rather than hammering on the face. If the equipment runs at high speed or elevated temperature, check the manufacturer's data for the correct lip material and elastomer before installing.
If you are cross-referencing, send the original part number together with the shaft, housing and height dimensions. With those three values we can search for an alternative in the same radial shaft seal category. We can also help if design A 293 does not match your housing exactly, so you avoid ordering a part that will not fit.

Frequently asked questions
- How do I confirm the DBH 1282 replaces the seal I have?
- Measure three things on the old seal or the equipment: shaft diameter, housing bore and height. They should read 55 mm, 102 mm and 8.00/10.00 mm respectively, with design A 293. If those match, it is a direct replacement. If the height falls elsewhere in the range, it may still seat correctly — send us a photo or the original number and we will confirm.
- Can you supply a different size or an equivalent seal?
- Yes. Send the original part number and the shaft, housing and height dimensions. We look for an alternative within the same radial shaft seal category, and if design A 293 does not suit your housing we help you find the right option.
- What should I check before installing this seal?
- Look for burrs, scratches or wear on the shaft, and make sure the housing bore is clean and undeformed. Lubricate the lip, insert the seal perpendicular to the shaft and press it in without striking the face directly. For high-speed or high-temperature service, verify the lip material and elastomer against the manufacturer's data.
