LVK Series
- Designed for direct mounting on SAE J620 and metric flywheels
- Element bonded to flywheel mounting plate and LK style hub housing
- Available in high temp rubber (HTR) or EPDM
- Nominal torque: up to 5,800 in-lb (655 Nm)
The LVK Series is designed for direct coupled equipment. The LVK Series coupling is highly torsionally compliant, allowing the engine to drive a large inertia load safely away from damaging torsional resonance or critical speeds. The coupling selection should be verified with a Torsional Vibration Analysis of the system
