How to increase torque without changing the coupling

At Lindis, we develop innovative solutions to enhance the performance of power transmission systems without compromising efficiency or cost-effectiveness. In many industrial applications, couplings are increasingly required to transmit higher torque, demanding more robust components without altering the original assembly design.

That's why we've added urethane and Hytrel stars to our product range, specially designed to improve the mechanical performance of HRC, JAW and N-FLEX couplings. Thanks to the advanced properties of these materials, you can:

  • Significantly increase torque transmission by simply replacing the elastomer insert

  • Keep the existing coupling, avoiding redesigns or additional investment

  • Optimise maintenance, as the star can be replaced quickly and easily

  • Improve system durability under dynamic loads, wear and fatigue
     

Which star is right for your application?

The materials used in the stars are key to a coupling’s ability to handle more torque and operate in demanding conditions. Below are the available options:

Urethane stars and elastomers

Urethane is a technical material known for its excellent combination of elasticity and wear resistance. Its versatility makes it ideal for standard or medium-duty applications where increased torque is required without losing flexibility.

Thanks to its molecular structure, urethane elastomers can boost torque transmission by up to 50% compared to conventional rubber stars. They are fully compatible with HRC and N-FLEX couplings, offering an immediate performance upgrade through a simple replacement.

Hytrel star

Hytrel is a high-performance thermoplastic elastomer developed by DuPont that combines the mechanical strength of plastics with the flexibility of rubber. Its main advantage is high torsional stiffness, making it ideal for systems requiring precise torque transmission and movement control.

This material is recommended for JAW couplings in applications with high torque demands and a need for a stiffer dynamic response. Its durability and performance under variable loads make it the preferred choice for demanding industrial environments.
 

Key system advantages

Easy and quick replacement
Replace only the elastomer without disassembling the coupling or touching the shaft.

Full compatibility with existing couplings
Designed to fit directly into HRC, JAW and N-FLEX models.

Cost savings
Lower expenses on parts, maintenance and production downtime.

Longer component life
Technical materials enhance resistance to fatigue, abrasion and cyclic loads.
