Information
Handwheels GN 228 of sheet steel or stainless sheet steel are robust and unaffected by shocks and knocks. The hub lengths l1 and the diameter d3 correspond to DIN 950.
The stainless steel design is suitable for applications in highly corrosive environments thanks to the A4 materials used.
On the revolving handles of type D, the O-rings minimize the radial play, protect the handle bearing from penetrating dirt and prevent noises resulting from vibration.
