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.

Jaw Couplings

Advantages

Vibration Damping : The elastomer spider (insert) effectively absorbs shocks and vibrations, protecting connected machinery.
Maintenance-Free Operation : No lubrication required, reducing long-term maintenance.
Compact Design : Small size and high torque transmission capacity make it ideal for space-constrained applications.
Fail-Safe : Even if the elastomer fails, the jaws continue to transmit torque, ensuring emergency operation.
Easy Assembly : Simple plug-in design allows quick installation and replacement of the elastomer insert without disturbing hub alignment.
