| 120:1 | 7.8 | 28 | 11 | 54 |
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-14SS-XX, where XX is the ratio (for example THD-14SS-80). Price ₹33,343 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.

Send your motor detailsQuestions about the THD-14SS
Is the price the same for every ratio?
Yes. The THD-14SS costs ₹33,343 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-14SS?
Use order code THD-14SS-XX with XX replaced by the ratio, for example THD-14SS-80. Send the order code, quantity and your motor model, and we confirm the coupling or adapter flange you need.
How do I connect the motor?
Through a standard shaft coupling, or a belt and pulley on the solid input shaft. We can supply a custom coupling bored to both shafts.
