Precision, to the arcsecond.
Zero-backlash strain wave gears: designed, machined, and bench-verified in-house. Scroll to look inside.
Rigid mounting interface: your load bolts straight to the flexspline output. Output · load
Fixed outer ring with two more teeth than the flexspline: that difference is the reduction. Fixed · housing
A thin steel cup deflected by an elliptical cam: full-depth tooth engagement, zero backlash. As low as 15″
Stator windings around the rotor drive the wave generator directly: no belts, no couplings. Input · high speed
Optical disc on the input shaft closes the position loop to arcsecond resolution. Feedback · 23-bit
Integrated servo electronics: commutation, current loop, and fieldbus on one board. EtherCAT · CANopen
Numbers we sign our name to.
Eight series. Ninety-five part numbers.
Integrated harmonic servo joints, force-sensing and lightweight variants, rotary and linear actuators, and bare strain wave gears. Peak torque to 2,700 N·m, every unit to the same published spec.
Trust is earned in measurement.
We hold the tolerances on our own machines and verify rated behaviour on the bench before a unit leaves the building.
Tooth geometry, held in-house
Flexspline and circular-spline profiles cut and inspected against the design geometry on critical features.
Backlash, measured on every unit
Angular play measured on the bench and logged to the serial number, against each series' published limit. Ships only if it passes.
Running torque & friction
No-load running torque and starting torque checked across the rotation for smoothness and no tight spots.
Test record with every drive
Each unit ships with its measured backlash, torque, and ratio matched to its serial number.
Where they run.
Anywhere a machine has to stop exactly where it's told.
Collaborative & industrial arms
Compact, coaxial reduction at the joint: high stiffness and repeatable positioning.
Stabilised platforms & gimbals
Arcsecond pointing for optics and antennas under motion and vibration.
Indexing & rotary axes
Rigid, repeatable positioning for tool changers, index tables, and 5-axis heads.
Surgical & imaging motion
Smooth, quiet, backlash-free actuation where precision is non-negotiable.
Wafer handling & metrology
Fine angular resolution for stages and handlers in tightly-toleranced fabs.
Precision positioning stages
Where the arcsecond is literally the unit of work: mounts, trackers, benches.
Engineering notes.
How strain wave gears work, how to size them, and how to read the datasheet, written by the engineers who machine and measure them.
Harmonic, planetary, or cycloidal? Choosing a robot-joint reducer
Five questions that decide which reducer family belongs in your joint, with real catalogue numbers rather than adjectives.
ReliabilityHow harmonic drives fail: wear, fatigue, and ratcheting
One failure mode is a clock, one is a cliff, one is an accident. What accelerates each, and the operating decisions that set your service life.
Engineering dataHarmonic drive efficiency: why the datasheet number isn't what you'll get
Rated efficiency is true at one operating point. The loss mechanisms, the three torque numbers nobody reads, and why gravity axes always get brakes.
MetrologyOne encoder or two? Position feedback for precision joints
A motor-side encoder sees the motor, not the load. What bit-depth actually buys, and when dual-absolute feedback earns its cost.
SelectionEtherCAT, CANopen, or CAN-FD? Picking the bus for a multi-axis machine
The bus decides where your control loops can live. Cycle times, sync, wiring, cost, and the one question that settles it.
Application notesMotor current or torque sensor? Choosing a force-control strategy
Motor current is a rumour of output torque, filtered through friction. When the rumour is good enough, and when only a calibrated sensor will do.
Talk to an engineer.
Tell us the load, the speed, and the space you have. We'll size the drive, name a part number, and quote, usually the same working day.
