Freudenberg: New Coating Reduces Wear and Shaft Runout in the Seal
The optimum function of rotary shaft seals depends on many factors. One of them is the wettability of the sealing lip. This parameter plays a particularly important role with synthetic lubricants such as polyglycol. If wetting is too low, not only does wear on the sealing lip increase, but the contact with the rotating shaft can also damage the shaft itself.
