Radial shaft seals such as the DBH 1259Vit are used in applications where a rotating shaft must be sealed against lubricant leaks and the ingress of dust or water. They are common in gearboxes, centrifugal pumps, electric motors, conveyor rollers and agricultural or construction machinery. Their function is to protect the bearings and extend the service life of the assembly, preventing oil loss and lubricant contamination.

To select a seal correctly, verify that the shaft, housing bore and height dimensions match those of your equipment's housing and shaft. Rotation speed, operating temperature and the type of lubricant influence the choice of lip material and spring. During installation, lubricate the lip, avoid damaging it with sharp edges and make sure the housing is clean and free of burrs. Careful installation prevents premature leaks.
