The DBH 9828Tef is a radial shaft seal built to the A 311-R design. It keeps lubricant in and contaminants out where a shaft turns inside a housing, which makes it a common choice for gearboxes, pumps, motors and similar transmission equipment. The lip and body geometry are matched to the operating speed, temperature and fluid of the machine.
The A 311-R designation describes how the lip and metal body are put together, not the mounting size. For a replacement, the code stamped on the old seal or caliper readings from the shaft and housing are what confirm the correct part. Send either one and we can cross it.
You will find this type of seal on gearbox input and output shafts, centrifugal pumps, electric motors, rollers and power transmission drives. In those positions it does two jobs at once: holding oil or grease inside the assembly and keeping dust, water and particles out. Machine tools and process equipment with continuous rotation rely on the same principle to keep lubricant clean.
Before installation, inspect the shaft for burrs, wear or incorrect roughness that would prevent the lip from sealing, and make sure the housing is clean and free of dents. Lubricate the lip with the same oil or grease used in the equipment, then press on the outer ring with a tube or spacer. Never push on the lip. If the shaft shows a wear groove, setting the seal slightly offset can let the lip run on a fresh surface.
To request a quote for the 9828Tef, send the complete code by WhatsApp along with a photo of the part and the shaft and housing dimensions. With those details we can locate the equivalent in the DBH line or in another brand we supply, and advise on lip design and material for the fluid and working temperature involved.

Frequently asked questions
- What does the A 311-R design mean in this seal?
- It refers to the lip and body configuration under the manufacturer's nomenclature. It tells you how the seal works and how it is fitted, but the shaft and housing dimensions still have to be confirmed separately before quoting.
- How do I ask for an equivalent of the 9828Tef?
- Send the full code by WhatsApp, a photo of the part and the shaft and housing dimensions. We then look for the equivalent in the DBH line or in another brand we carry and send you the quote.
- What should I check before installing a radial shaft seal?
- Check that the shaft has no burrs or wear, that the housing is clean and free of impacts, and lubricate the lip before installing it. Use a tube that presses on the outer ring, never on the lip, so you do not damage it.
