Flexible Gear Couplings

High performance and easy in installation manufactured using fully automatic hobbing machine.

Roller Chain Couplings

Roller Chain Flexible Couplings are compact, long lasting flexible couplings, capable of transmitting relatively high torques with minimum of space consumption

Torque Limiter

Nu-Teck torque limiter is a protective device that limits torque transmitted in a drive system by slipping when torque demand exceeds a preset value as a result of shock loads, over loads, or machine jams.

Sprockets

Nu-Teck Sprocket Wheels are manufactured from quality materials. Teeth are hob-cut for correct tooth form, tooth thickness and profile.

Disc Couplings

NU-TECK Disc Couplings are torsionally rigid and completely backlash-free, designed for high-performance drive systems requiring precise positioning, maintenance-free operation, and reliable misalignment compensation. Torque is transmitted through FEA-based optimised stainless steel disc packs made of thin spring steel discs, precisely connected by high-accuracy sleeves and secured to the hubs—directly or via spacers—using high-strength fitted bolts. Optimised sleeve relief grooves reduce load peaks during shaft misalignment, improving service life. Depending on application requirements, disc packs provide increased misalignment capability while offering higher torque density. This modular design with multiple hub, adaptor & spacer options ensures optimal adaptation to a wide range of applications, including customised solutions with fast turnaround times.

Features Highlight :

High Power-to-Weight Ratio : Lightweight, high-strength design with excellent high-speed performance and inherent balance
Zero Backlash & High Torsional Rigidity : Ensures precise torque transmission with low axial stiffness for dynamic applications
Maintenance-Free Operation : No wearing parts and no lubrication required, reducing downtime and operating costs.
Excellent Misalignment Capability : Accommodates angular, parallel, and axial misalignment with minimal restoring forces
Easy Installation & Inspection : Removable spacer design allows quick installation and visual inspection without removing equipment from its foundation
Robust & Temperature Resistant : Durable anti-corrosive coating on non-stainless components and suitable for high-temperature applications
Flexible Configurations : Available with custom spacer lengths, modified hubs, special materials, dynamic balancing to customer specifications
