Benefits

Why choose the HEXAFLEX?

The HEXAFLEX optimises spider geometry to transmit more torque for longer.

01 / ADVANTAGE

Optimised geometry

The 6-leg spider of the HEXAFLEX distributes the load over more contact points than a classic 4-leg spider. Torque transmission capacity superior for equivalent footprint.

02 / ADVANTAGE

Service life

The balanced load distribution over the 6 legs reduces local stress peaks. The spider lasts significantly longer than a 4-leg spider under equivalent conditions.

03 / ADVANTAGE

Multi-hardness

The hexagonal spider is available in several hardnesses (standard rubber, polyurethane, thermoplastic elastomer) to adapt to the constraints of each application.

Product description

The HEXAFLEX elastic coupling offers an elastomer spider geometry with 6 legs (hexagonal), instead of the 4 classic legs of standard Jaw-Flex couplings. This optimised geometry offers two decisive advantages.

First, the torque transmission capacity is superior to that of a 4-leg spider of equivalent footprint: the load is distributed over 6 contact points instead of 4, which reduces the local stress on each leg.

Second, the service life of the spider is significantly extended: fewer local stress peaks, less asymmetric wear, more predictable behaviour over time. The hexagonal spider is available in several hardnesses (rubber, polyurethane, thermoplastic elastomer) to adapt to the specific constraints of each application.

  • Hexagonal elastomer spider (6 legs) — optimised geometry
  • Torque capacity superior to classic 4-leg spiders
  • Balanced load distribution — improved spider service life
  • Adequate tolerance to misalignment
  • Moderate damping of torsional vibrations
  • Interchangeable spider in several hardnesses
