Overview
Top-hat (silk-hat) flexspline with an integrated cross-roller output bearing. Bolt it on, couple the motor and the joint is done.
Typical uses: 6-axis industrial robots, SCARA and delta robot axes, CNC rotary 4th axes, laser and welding positioners.
Ratings

| 120:1 | 137 | 353 | 216 | 686 |
Input speed: up to 4,800 rpm maximum, 3,500 rpm average. Design life: 10,000 h at 50:1, 15,000 h at 80:1 and above.
Ordering
Order code THD-32H-XX, where XX is the ratio (for example THD-32H-80). Price ₹42,869 per unit, ex-works Rajkot, excluding GST and freight, the same for every ratio. MOQ 1 piece; ask for volume pricing from 10 pieces. Send your motor model with the order and we confirm the coupling or adapter flange you need.
Ratings are typical values from manufacturer tests and are for guidance only. Real performance depends on installation, load, lubrication and environment; confirm your selection with Torqtron engineering. Photographs are representative of the series.

Send your motor detailsQuestions about the THD-32H
Is the price the same for every ratio?
Yes. The THD-32H costs ₹42,869 per unit, ex-works Rajkot, excluding GST and freight, for any ratio (50:1 to 120:1). MOQ is 1 piece; ask for volume pricing from 10 pieces.
How do I order the THD-32H?
Use order code THD-32H-XX with XX replaced by the ratio, for example THD-32H-80. Send the order code, quantity and your motor model, and we confirm the coupling or adapter flange you need.
Does the hat unit need a separate output bearing?
No. The integrated cross-roller bearing carries the radial, axial and tilting loads of the joint, so the unit bolts straight in.
