Slit couplings / grub screw locking, feather key / cross slot / body: stainless steel / SRBS-22 / SUNGIL (Part Numbers - CAD Download)

This set screw type slit coupling has a low moment of inertia and stability even at high RPM.
[Features]
・ Spring with 0 backlash and radial beam absorbs eccentricity, declination, and end play.
·A long type, with high torsional rigidity and torque tolerance, and high oil and chemical resistance.
・ The characteristics of forward/reverse rotation are the same and no repair is required.
[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.
