Slit Coupling Clamping Type SRBA

Slit Coupling Clamping Type SRBA

Clamping type slit coupling that has a low moment of inertia and is stable even at high rotations.
[Features]
・ Spring with 0 backlash and radial beam absorbs eccentricity, declination, and end play.
·It has high torsional rigidity and torque tolerance, as well as high oil and chemical resistance.
·A long type, identical forward/reverse rotation characteristics, no need for repair.
[Applications]
・ Optimal for serial drive of transmission equipment, position control / positioning table, robot system, boring, and polishing machine.
·Can be used for machining centers (machine tools), medical equipment, servo motors, speed reducers, etc.
