This is feedback from Germany.
Saniline is typically used in food machinery, but this is an example from a car wash application. One of the major advantages of Saniline is its maintenance-free, relubrication-free design, which eliminates the risk of grease leaking from the bearing and contaminating vehicles.
With the bearings previously used, corrosion was also an issue. Since the machine is made of stainless steel, switching to Saniline has eliminated the corrosion problem as well.
