Part 9757 from DBH is a radial shaft seal built to hold lubricant inside a housing and keep dust, grit and moisture out wherever a shaft turns. Its Kx configuration pairs a sealing lip with a spring, so the lip stays in contact with the shaft as it rotates. Shaft 49.20 mm, housing 80.90 mm, height 11.00 mm. Maintenance and purchasing teams specify it for gearboxes, pumps, motors and transmission assemblies.
Reading the code helps when you cross-reference. The four digits 9757 identify the size within the DBH range, while Kx tells you which lip and spring arrangement you are getting. The three figures that matter for fit are the shaft diameter, the housing bore and the height: 49.20 mm, 80.90 mm and 11.00 mm respectively. If your bore or shaft measures differently, the seal will not seat or seal correctly, so confirm all three before ordering.
In service, this seal sits between a rotating shaft and a fixed cavity. It keeps oil or grease where it belongs and stops outside particles from reaching bearings and gears. Common installations include gearboxes, centrifugal pumps, electric motors, compressors and transmission rollers. A worn or damaged lip lets lubricant escape and contamination enter, which is a frequent cause of bearing failure and unplanned downtime.
Installation is straightforward when the bore and shaft are prepared first. Remove burrs, scratches and old seal residue, then coat the lip with the same lubricant used in the unit. Drive the seal in with a press or a proper installation tool, keeping force even around the outer diameter. The spring faces the lubricant side and the lip must not roll or invert. On a shaft with visible wear, a taller seal may seat on a fresh surface.
