The DBH 6763Pol is a radial shaft seal built to keep oil or grease inside a housing while blocking dust, water and other contaminants from reaching the bearing area. It fits equipment with a rotating shaft, such as gearboxes, pumps and electric motors, and its 54 mm shaft, 81.10 mm housing and 21 mm height let you swap out a worn seal without touching the housing itself. MR Industrial Accessories supplies this seal as part of its seals and oil seals line.

The 6763Pol carries the DBH brand and the A 102 design, which means a single lip with a spring for shafts under permanent lubrication. A metal outer case presses into the housing bore, while the elastomeric lip rides against the shaft to close off the chamber in both directions. Shaft diameter is 54 mm, housing diameter is 81.10 mm and the height is 21.00 mm.

You will find seals in this size range in gearboxes, centrifugal pumps, electric motors, rollers and transmission equipment, as well as machine tools and process machinery with continuous shaft rotation. In every case it works together with a bearing or bushing that depends on retained lubricant and protection from outside contamination. The 21 mm height gives a broad support surface, which helps where there is slight misalignment or vibration.

Before ordering, confirm the three dimensions against the original part: shaft, housing and height. Look at the shaft surface as well, since a scratched or worn track will keep the lip from sealing even when the size is right. At installation, coat the lip with the same oil or grease used in the unit, set the seal perpendicular to the shaft, and tap only on the outer face of the case, never on the lip. Remove any burrs from the housing bore first.

To get a quote on the 6763Pol, or on a seal you are currently using, send the part number or the shaft, housing and height measurements by WhatsApp or email. We check the DBH line and other radial seal options that match. If the A 102 design does not suit your application, we can point you toward a different lip type or material. The more details you share about the equipment, the more precise the match.
