StarVars Interactive Pfaff-CAD is a powerful web-based design tool for designers to engineer online, in 2D or 3D, actuators for their machinery applications.

Files can be exported and downloaded in the following formats: AutoCad dwg and dxf; SAT; STEP; as well as in several conventional graphic file formats for non-cad purposes.




Pfaff-silberblau actuators are found on machinery all around the world. With some basic nameplate information we can identify your actuator to provide you with a full replacement or parts for repair and overhaul. Standard parts such as worm gears, worm wheels, guide rings, bearings and seals for jacks up to 15 tonne capacity can usually ship next day from our Toronto warehouse.
