Servomotor Precision Flexible Shaft Coupling
Manufacturer part: 6853N105
Connect shafts and ball screws to high-speed servomotors and stepper motors—these shaft couplings handle four times more speed than standard servomotor couplings. They’re often found on high-torque motors that frequently start and stop, such as those used with packaging machines, press brakes, and semiconductor manufacturing equipment.With aluminum hubs joined by a flexible fluoroelastomer or nitrile rubber core, these shaft couplings dampen vibration and adjust for misalignment. When machines accelerate and decelerate quickly, these couplings remain stiff to maintain accuracy and repeatability, which prevents equipment from moving out of place. They also resist backlash, meaning all of the turning force from the motor is passed on to the connected shaft. The core resists water, petroleum-based chemicals, and inorganic acids while also insulating bearings, encoders, and other shaft components from stray electric current. Clamping screws provide hold without marring shafts; they’re useful in applications where shafts are frequently assembled and disassembled.
