Hollow shaft for the feed-through of cables, fast and cost-effective installation
Three mounting options: straight, right-angle, pulley
Completely enclosed, delivered pre-filled with lubricant
Three mounting versions for easy assembly
While the RDR-C series is designed for right-angle mounting, the RDS-C series is suitable for straight mounting and the RDP-C is the pulley input option. This enables fast, cost-effective installation and diverse application options: The efficient and extremely precise cycloidal gears are ideal for numerous applications, from machine tools to robotics systems and woodworking machinery. We deliver the hollow shaft gearheads of the RD_-C series pre-filled with lubricants and completely encapsulated. This means they are immediately ready for use in your system!
