For equipment that needs a reliable barrier around a rotating shaft, the DBH 8491 radial shaft seal fits a 29.85 mm shaft, a 47.00 mm housing bore and an 11.30 mm height. Its A 075-Bidi design uses a double-lip layout to help keep lubricant in and contaminants out. This seal is available from MR Industrial Accessories LLC, which supplies sealing components to maintenance and purchasing teams across the United States and Latin America.

The DBH 8491 belongs to the DBH line of radial shaft seals. The part number 8491 identifies this specific size, while the A 075-Bidi code describes the lip arrangement: two sealing lips that work in both directions. The seal combines an elastomer body with a metal case, and the exact compound should be confirmed on the manufacturer's data sheet before installation.

You will find this seal in gearboxes, centrifugal pumps, electric motors and other power transmission equipment. Its role is to hold oil or grease inside the housing and to block dust, water or particles from reaching the bearing. It suits 29.85 mm shafts running at moderate speeds and normal operating temperatures where a dependable seal is required.

When installing the DBH 8491, make sure the shaft and housing bore are clean and free of burrs. Apply a light coat of the same lubricant used in the machine to the lip before pressing the seal into place. Selection should account for peripheral speed, temperature and chemical compatibility with the fluid. If the shaft shows wear, consider a seal with an auxiliary lip.

To request a quote, send part number 8491 or the three dimensions of your current seal: shaft diameter, housing bore and height. A photo of the part and the housing also helps. The team at MR Industrial Accessories LLC can review alternatives within the same brand or from other lines we carry, while respecting the original tolerances and design.
