Jaw-Flex coupling LN Series (Elastomer 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.
- ・Applicable shaft diameter :Φ12mm~Φ42mm
- ・Torque range :60~405N・m
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.
