Mouting Suggestion
Housing – Ø: Mounting bevel, min. 1,5 mm x 15-45°
Shaft Material:Hardened steel, surface roughness < Rz 6,3
Shaft: Mounting bevel, 5 mm x 15°, edges rounded
Force fitting mandrel: The application of an adequate force fitting mandrel is advisable. Grease lubrication of the outer surface may be necessary when mounting.
