Input speed: up to 8,500 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-14C-XX, where XX is the ratio (for example THD-14C-80). Price ₹26,992 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-14C

Is the price the same for every ratio?

Yes. The THD-14C costs ₹26,992 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-14C?

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

Do I need my own housing and output bearing?

Yes. THD-C is a component set (wave generator, flexspline and circular spline) built into your own housing and bearings. If you want a housed unit with an output bearing, look at the THD-H Hat or THD-HB Hollow Bore series.
