Jaw-Flex Coupling LN Series (Elastomer Coupling)

A new material has been used for the spider, achieving unprecedented vibration damping.
Torque can be transmitted without backlash, and servo motor drive provides excellent shock absorption.
・Applicable shaft diameter: Φ12mm to Φ42mm
Torque range: 60 to 405 Nm

Features

- Servo motor drive provides excellent vibration countermeasures and shock absorption during start-up and shutdown.
- The optimal combination of spider and hub allows torque to be transmitted without backlash, even though it is Jaw-Flex coupling.
-You can choose from two types of spiders: 98A, which has excellent vibration damping properties, and 64D, which has high torsional rigidity and excellent wear resistance.
- It has a simple structure consisting of two hubs and one spider, and the clamp-type shaft fastening method makes installation easy.
・Taper lock fastening is also available. Please contact us.
