💡 Why are jaw type flexible couplings used in motor drive systems?
Jaw couplings are widely used to protect equipment while keeping power transfer smooth.

• Absorb shock loads that can damage motors and bearings

• Reduce vibration transferred between connected shafts

• Allow minor misalignment without stressing components

• Improve service life in motor driven mechanical systems

This coupling is a handy solution for motor and drive setups where smooth operation, reduced wear, and reliable power transfer really make a difference.
