Ordering

Order code THD-14U-XX, where XX is the ratio (for example THD-14U-80). Price ₹37,471 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.

Questions about the THD-14U

Is the price the same for every ratio?

Yes. The THD-14U costs ₹37,471 per unit, ex-works Rajkot, excluding GST and freight, for any ratio (50:1 to 100:1). MOQ is 1 piece; ask for volume pricing from 10 pieces.

How do I order the THD-14U?

Use order code THD-14U-XX with XX replaced by the ratio, for example THD-14U-80. Send the order code, quantity and your motor model, and we confirm the coupling or adapter flange you need.

What comes with a THD-U unit?

The harmonic gear in its housing with a motor flange and an output plate, ready to bolt to a servo. Outline and mounting dimensions are in the drawing below; ask for the delivery drawing (2D or 3D STEP) before you machine mating parts.
