One enquiry. The complete mtion axis.
Most machines need more than one part. Tell us about the motion and we'll specify the controller, drive, motor, gearing, feedback and slip ring so they work together, with one point of contact from prototype to production.
Applications
Engineered for your industry
Each application guide covers the requirements, the standards and the full set of components it usually needs, with a spec builder set up for that use.
Robotics and automation
Compact joints, end effectors and pick-and-place axes.
Defence and security
Turrets, hatches and positioners built for shock and EMC.
Satellite and comms
Antenna positioners with slip rings and absolute feedback.
Energy and renewables
Pitch and yaw slip rings and solar tracker actuators.
Packaging and machinery
Filling, forming and wrapping axes, including washdown.
Medical and laboratory
Quiet, low-cogging motion for imaging and lab automation.
Entertainment and rides
Ride systems, stage revolves and camera motion.
Transport and logistics
Conveyors, cranes, cable reels and AGV drive modules.
Technical guides
Selection guides written by engineers
How to specify a slip ring
Circuits, current, data, speed, sealing and life: what to decide before you request a quote.
Replacing a hydraulic cylinder with an electric actuator
Sizing force and duty, roller or ball screw, and what changes in your control system.
Harmonic vs planetary vs cycloidal gearboxes
Backlash, stiffness, torque density and cost compared for robot joints and indexing axes.
