The DBH 9828Tef oil seal is a radial shaft seal with A 311-R design, intended to retain lubricant and block the entry of contaminants on rotating shafts. It is used in gearboxes, pumps, electric motors and power transmission equipment where the seal runs on a shaft and inside a housing. Its geometry and material are selected according to the speed, temperature and fluid of the equipment. At MR Accesorios Industriales we carry it as part of our seals and oil seals line.

This item is a DBH radial shaft seal with designation 9828Tef and A 311-R design. The A 311-R design defines the lip and metal body configuration, but it does not by itself set the mounting dimensions. The dimensions of this particular part number are confirmed against the manufacturer's data sheet before quoting, because the record does not include diameters, width or numerical tolerances. If you need to replace an existing oil seal, the safest option is to send us the part number engraved on the part or the measurements taken with a caliper.

Typical applications for a radial shaft seal like this one are input and output shafts of gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all those cases the seal serves two functions: retaining the oil or grease inside the assembly and preventing dust, water or particles from entering. It is also used in machine tools and process equipment where there is continuous rotation and a need to keep the lubricant clean.

To install an oil seal, check the condition of the shaft: no burrs, no wear and with the proper roughness for the lip to seal. The housing must be clean and free of dents. It is advisable to lubricate the lip with the same grease or oil used in the equipment before inserting it, and to use a tube or sleeve that presses on the outer ring, never on the lip. If the shaft has a wear mark, the seal can sometimes be installed slightly offset so that the lip runs on a healthy area.
