This item is a radial shaft seal from the DBH brand, identified by the code 5681Sil. Its standard dimensions are: shaft diameter (d) 35 mm, housing bore diameter (D) 52 mm and height (h) 8.80 mm. The Mz design corresponds to a specific lip and case configuration that ensures effective sealing under rotating conditions. It is a precision part that is press-fitted into the housing and runs on the shaft, preventing oil or grease leaks and the ingress of dust or water.

Radial shaft seals such as the 5681Sil are used in a wide variety of industrial equipment: gearboxes, centrifugal pumps, electric motors, compressors, spindles and belt or chain drives. Their function is critical to keeping lubrication inside the assembly and protecting bearings and gears from external contamination. In environments with dust, chips or moisture, a seal in good condition extends component service life and reduces maintenance downtime.

To correctly select a seal, in addition to the dimensions it is essential to consider the operating conditions: shaft peripheral speed, working temperature, type of lubricant and differential pressure. The Mz design offers particular sealing characteristics that must be evaluated according to the application. During assembly, check that the housing and shaft are clean and free of burrs, lubricate the lip with the same service oil or grease and fit the seal perpendicular, without striking it directly. Careful installation prevents premature damage and leaks.
