The DBH 9775 is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 27.95 mm shaft, a 70 mm housing bore and a 10.00 mm height, and uses the A 301-R-H lip-and-spring design. MR Industrial Accessories LLC supplies this seal to maintenance and purchasing teams across the United States and Latin America.

This seal is identified by part number 9775 and belongs to the DBH line. The three dimensions to match are shaft 27.95 mm, housing bore 70 mm and height 10.00 mm. The A 301-R-H designation describes a sealing lip with a spring, made for rotating shafts. Its job is to close off the passage of oil or grease in gearboxes, pumps, electric motors and similar rotary equipment.

In service, the seal holds lubricant around bearings and blocks dust, water and other particles from entering. You will find it in power transmission units such as gear reducers and gearboxes, as well as in centrifugal pumps and industrial fans. The lip and spring work together to maintain even contact on the shaft, which supports sealing under continuous rotation.

For installation, clean the shaft and housing and remove any burrs. Apply the same oil or grease used in the equipment to the lip before fitting the seal. Press it in perpendicular to the shaft with even force on the outer circumference, never on the lip. The spring must face the fluid being retained. If the shaft is worn, a seal with greater height may be a better choice.
