KTN110 Hollow Rotary Platform is a high-precision motion platform designed for compact, automated systems. It integrates a crossed roller bearing that provides exceptional rigidity and load-bearing performance, maintaining stability even during high-speed operation. With available gear ratios of 5:1 and 10:1, it delivers torque output of up to 47 N·m and allows a top rotational speed of 100 rpm.
The internal low-backlash gear system ensures accurate repeat positioning (±15 arcsec), making KTN110 suitable for tasks requiring precision indexing, synchronized rotation, or multi-axis motion control. The center hollow design simplifies the routing of electrical and pneumatic components, increasing system efficiency and reducing installation complexity.
Motor Installation Instructions
First, match the size of the motor and the hollow rotating platform and remove all foreign matter from the surface.
Remove the screw plug on the adapter flange and adjust the position until the fastening bolts can be seen.
Adjust the position of the motor and the adapter flange and gently tighten the fastening bolts. The paper locking ring will no longer rotate idly.
Preliminary tightening of the bolts diagonally, after completing step 5, refer to the tightening torque standard Ta and tighten the fastening bolts.
Refer to the tightening torque standard Tb and tighten the fastening bolts.
Tighten the screw plug.
