Cassette Seals

A final step in preparation for assembly is to lubricate the shaft, sealing lip and bore with sufficient oil. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. Always use oil or grease that is compatible with the oil seal material. In addition, when sliding over the shaft, the oil seal comes into contact with the keyway, threads and grooves. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.
