The DBH 9828Tef seal is a radial shaft seal with an A 311-R design, intended to contain lubricant and block the entry of contaminants on rotating shafts. It is used in gearboxes, pumps, electric motors and transmission equipment where the seal works 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 the designation 9828Tef and A 311-R design. The A 311-R design defines the configuration of the lip and the metal body, but by itself it does not set the mounting dimensions. If you need to replace an existing seal, the safest option is to send us the code engraved on the part or the dimensions taken with a caliper.

Typical applications for a radial shaft seal like this are input and output shafts of gearboxes, centrifugal pumps, electric motors, rollers and power transmission equipment. In all those cases the seal performs 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 a seal you have to check the condition of the shaft: no burrs, no wear and with the right roughness for the lip to seal. The housing must be clean and free of impacts. 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 spacer that presses on the outer ring, never on the lip. If the shaft has a wear mark, sometimes the seal can be installed slightly offset so the lip works on a healthy area.
