The DBH 8491Pol is a radial shaft seal built for rotating shaft applications. It keeps lubricant where it belongs and keeps dust, water and particles out, protecting the bearings and bushings around it. The seal measures 29.85 mm at the shaft, 47 mm at the housing bore and 11.30 mm in height, and it carries the A 075-Bidi designation. MR Industrial Accessories supplies this brand as part of its seal line for customers in the United States and Latin America.

The part number 8491Pol belongs to the DBH line of radial shaft seals. Reading the dimensions in order: shaft 29.85 mm, housing bore 47 mm, height 11.30 mm. The A 075-Bidi code points to a double-lip layout, so the sealing edge works in both directions and handles external contamination as well. Sealing against the rotating shaft comes from the elastomer lip together with its internal spring.

You will find seals like the 8491Pol in gearboxes, pumps, electric motors, transmission shafts and process equipment. Retaining oil or grease while blocking dirt is what makes them important in dusty, wet or frequently washed-down areas. In food, chemical and material handling operations, a seal in good condition is what keeps bearings running and the assembly in service.

Selection starts with the three dimensions: shaft, housing bore and height must match the product. Peripheral speed, operating temperature and the lubricant in use decide the lip and spring material. The A 075-Bidi design gives a double barrier, but it also calls for a properly finished housing surface and good alignment between shaft and bore, otherwise leaks appear early.
