THK KR3310A-0200-P LM Precision Linear Positioner

The THK KR3310A-0200-P LM Precision Linear Positioner is a compact, high-precision linear actuator that combines THK’s integrated LM Guide with a precision ball screw, delivering a 10 mm lead and 200 mm of travel for fast, accurate linear motion. As part of the KR33 LM Guide Actuator Series, it uses a U-shaped high-rigidity outer rail with precision LM guide blocks and an integrated ball screw in a single compact assembly, designed for direct coupling to a NEMA 23 stepper or servo motor. Key specs include a maximum speed of 790 mm/s, a positioning repeatability of ±0.01 mm, and a backlash of 0.02 mm. The screw shaft diameter is 10 mm, with a ball screw lead of 10 mm, and the device supports four-way equal load capability for stable operation in automated pick-and-place, material handling, precision inspection, and other factory automation applications. Efficiency is approximately 90%, with a friction coefficient around 0.01, and it accepts a maximum input speed of 4,700 rpm and maximum input torque of 1.244 N·m.
