This item is a DBH brand radial shaft seal, identified by part number 8173. Its dimensions are 66.68 mm for the shaft diameter (d), 92.03 mm for the housing bore (D) and 11.90 mm height (h). The A 183 design corresponds to a single lip configuration with spring, suitable for applications requiring an effective barrier against dust and moisture. Made with high-resistance elastomers, it offers good elasticity and dimensional stability in continuous service.

Radial shaft seals such as the DBH 8173 are used in a wide variety of equipment: gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain drives. Their main function is to keep lubricant inside the assembly and prevent the entry of external particles that accelerate wear on bearings and shafts. They are also used in applications with moderate exposure to oils, greases and water, provided the peripheral speed and temperature are within the material's limits.

To correctly select a seal, verify that the shaft and housing dimensions match those of the original component. The shaft surface must be free of burrs, scratches or excessive wear; a rough finish accelerates lip wear. During installation, lubricate the lip with the same service oil or grease, insert the seal perpendicular and avoid striking it directly. If the shaft shows a worn track, consider using a wear sleeve or an alternative size.
