With dimensions of 29.85 mm shaft, 47 mm housing bore and 11.30 mm height, and an A 075-Bidi design, it is used in equipment requiring bidirectional containment. MR Accesorios Industriales sells this brand for the Argentine industrial market.

This item is a radial shaft seal from the DBH line, identified by part number 8491Pol. Its standard dimensions are: shaft diameter 29.85 mm, housing bore diameter 47 mm and height 11.30 mm. The A 075-Bidi design indicates a double-lip configuration, intended for applications where sealing must act in both directions or where external contaminants are present. The elastomer and the internal spring ensure sealing on the rotating shaft.

Radial shaft seals such as the 8491Pol are used in gearboxes, pumps, electric motors, transmission shafts and process equipment. Their ability to retain oil or grease and exclude dirt makes them critical in environments with dust, moisture or frequent washdowns. In the food, chemical or material handling industries, this type of seal protects bearings and extends the service life of the assembly.

To select a seal correctly, check that the shaft, housing bore and height dimensions match those of the product. Peripheral speed, operating temperature and lubricant type determine the lip and spring material. The A 075-Bidi design provides a double barrier, but it requires a housing with a suitable surface finish and correct alignment between shaft and bore to avoid premature leaks.
