  • Jaw-Flex Coupling

LN series

The LN Series Jaw-Flex Coupling delivers more vibration damping than our existing products by employing new material for the spider.

It also provides backlash-free torque transmission and superior shock absorption at servomotor drives.

All models are RoHS compliant.

1．Features

  • Excellent for vibration resistance at servomotor drives and shock absorption during startup and stopping.
  • With the combination of the optimally designed spider and hub, this Jaw-Flex Coupling series is capable of transmitting torque without backlash.
  • You can choose from between two types of spiders: 98A excellent for vibration damping; and 64D with high torsional stiffness and wear resistance.
  • Simply constructed with two hubs and one spider, uses a clamp shaft coupling method, making this coupling extremely easy to install.
  • Available for Taper-Lock Series. Contact a Tsubaki representative.
