In the railway and locomotive industry, power transmission components are subjected to relentless operational demands — including continuous heavy vibrations, extreme thermal variations, high starting torques, and dynamic braking forces. Drive systems must operate with absolute reliability across long distances and tight maintenance schedules.
At Nu-Teck, we supply high-performance Flexible Couplings alongside Precision Gears, Heavy-Duty Gear Pinions, Gear Shafts, and Precision Sprockets engineered for traction drives, braking systems, and auxiliary machinery.
| Application | Nu-Teck Coupling | Nu-Teck Advantage |
| Traction Drives & Main Propulsion | ||
| Diesel & Electric Locomotive Drives | High-Torque Gear / Disc Couplings |
Connects traction motors to axle gearboxes while accommodating high dynamic radial and angular track misalignment. |
| Auxiliary Generator Drives | Heavy-Duty Disc Couplings | Connects auxiliary engines to power generation units, delivering torsionally rigid, zero-backlash power transmission. |
| Brake Systems & Air Supply | ||
| Locomotive Air Compressor Drives | Flexible Jaw / Tyre Couplings | Dampens motor vibration and absorbs shock loads in brake compressors, ensuring smoot h air pressure delivery. |
