This item is a radial shaft seal from the DBH brand, identified by part number 9775. Its dimensions are 27.95 mm shaft diameter (d), 70 mm housing bore diameter (D) and 10.00 mm height (h). The A 301-R-H design corresponds to a seal with a sealing lip and spring, intended for rotating shafts. It is used to seal the passage of oil or grease in gearboxes, pumps, electric motors and other equipment with rotary motion.

Typical applications for this seal include retaining lubricant in bearings and excluding external particles. It is commonly found in power transmission equipment, such as gear reducers and gearboxes, as well as in centrifugal pumps and industrial fans. Its lip-and-spring design ensures uniform contact on the shaft, which contributes to effective sealing under continuous rotation conditions.

To install this seal correctly, make sure the shaft and housing are clean and free of burrs. Lubricate the lip with the same oil or grease used in the equipment before installation. Insert the seal perpendicular to the shaft, applying uniform pressure on the outer circumference, never on the lip. Make sure the spring is on the side of the fluid to be retained. If the shaft shows wear, consider a nearby size or a seal with greater height.
