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.

Pin Bush Couplings

The Pin Bush Coupling is a flexible power transmission solution designed to accommodate misalignment and dampen vibrations. Constructed from high-grade cast iron with resilient rubber bushes, it ensures smooth torque transmission with minimal backlash.

Flexible couplings are designed to transmit torque between two shafts and are especially effective in applications where slight shaft misalignment cannot be avoided. The Bush Type Flexible Coupling, designed as a cushioned drive system, transmits torque to the machine's input shaft through high-tensile steel bolts. Specially engineered rubber bushes are used to absorb shock loads, dampen torsional vibrations, and compensate for minor misalignments.

Advantages

Misalignment Compensation : Accommodates angular, axial, and radial misalignments, making it suitable for flexible installations.
Shock Absorption : Rubber or synthetic bushes dampen shocks and vibrations, protecting equipment.
Torsional Flexibility : The flexible nature of bushes helps in smooth torque transmission under variable loads.
Simple Construction : Robust and easy to assemble; ideal for medium to heavy-duty applications.
Cost-Effective : Economical solution for many industrial power transmission setups, with low maintenance needs.
