A radial shaft seal that presses into the housing and rides against the turning shaft, the DBH 5284 keeps lubricant inside the assembly and keeps dust, water and particles out. Its dimensions are shaft 70 mm, housing 90 mm and height 14.00 mm, and it comes in Lx design. Within the DBH line, the number 5284 identifies this particular size. It belongs to the seals and oil seals range that MR Industrial Accessories supplies.
Lx design means a single sealing lip with a spring and no secondary dust lip. That configuration suits assemblies where the lip faces the lubricant on the inside and where no extra barrier against outside contamination is called for. Typical installations include gearboxes, pumps, electric motors, transmission shafts and other rotating equipment, wherever oil or grease has to stay in and bearings have to stay protected from dirt.
Treat this seal as a wear part. Once the lip stiffens, splits or stops flexing, lubricant begins to escape and the bearing or the shaft can be damaged if the seal is left in place. Replacing it at the first sign of weeping is the cheaper route.
Before fitting a new seal, check that the shaft surface is clean and free of burrs or deep grooves across the contact band, and that the housing bore is undamaged. Coat the lip with the same oil or grease the equipment runs on, then drive the seal in with a tube or press that pushes on the outer diameter only. Never load the lip directly. Where the shaft is already worn, a seal with the lip positioned at a different depth may be the better choice.
To source an equivalent, send the complete code along with the shaft, housing and height measurements, plus a photo of the removed seal if you have one. That information lets us match the exact size from the lines we carry, and we can also tell you whether Lx is the correct design for your operating conditions.

Frequently asked questions
- What are the dimensions of the DBH 5284 oil seal?
- Shaft 70 mm, housing 90 mm, height 14.00 mm. It is a radial shaft seal in Lx design, meaning a single lip with a spring and no external dust lip.
- How do I check whether the Lx design suits my equipment?
- Lx has no dust lip, so it is intended for locations where the lip runs against the lubricant and no extra protection from outside contamination is needed. If the equipment sees heavy dust or water, another design may work better. Send us your application details and we will advise.
- Is there an alternative if the 5284 no longer fits my shaft or housing?
- Yes. If either surface is worn, another size can be considered. Provide the current dimensions and a photo of the old seal, and we will look for the most suitable option among the lines we carry.
