Choosing Quality Oil Seals for Wheel Hubs and Steering Mechanisms

oil seal 45 65 10. Its simple yet effective design allows for quick and hassle-free replacement, saving time and effort for maintenance personnel. This convenience factor makes it a popular choice among maintenance professionals looking for reliable sealing solutions.
An oil seal is designed to perform three major functions: to prevent lubricants from leaking outside the seal even under high pressure, to act as a barrier to retain the lubricating oil, and to prevent dirt and other contaminants from entering the unit.

For the housing stop installation technique, set the seal depth flush with the bore’s interior shoulder. This technique ensures that the seal is perfectly aligned with internal housing components. A depth gauge can be crucial here to confirm that the seal is positioned correctly.

Requirements of the shaft
Even more important than a correct interference fit of the Oil Seal is a perfectly smooth shaft in the region of the seal, particularly if shaft surface speed is high and the medium to be sealed is under a certain amount of excess pressure. The surface roughness of the shaft depends on the average profile depth Ra of the tool marks caused by the machining process. Oil Seals made of PTFE require, independent of the surface speed, a surface roughness of between 0,1 to 0,2 mm, because PTFE has less wear resistance than rubber seals. For normal circumstances, the shaft in the region of the seal must have a surface roughness of approximately: To summarize, the surface of the shaft in the region of the seal should not have noticeable machining marks. For pivoting shafts and other difficult or critical sealing applications, it is recommended that Oil Seals with a helical groove hydrodynamic pattern, which has a pumping effect, be used. When grinding and polishing, an axial movement of the grindstone along the shaft must be avoided in order to prevent machine lay.
