Product Description

Product Description

KGG High Quality ZR Actuator - ZRIN42 Series

KGG ZR Actuator delivers high-precision linear and rotary motion for demanding applications in automation, such as semiconductor handling, consumer electronics assembly, and precision manufacturing. Its compact direct-drive design integrates a hollow shaft motor, ball screw, and ball spline to achieve zero axial clearance, smooth movement, and a lightweight structure. Built for accuracy and reliability, it ensures superior performance in high-speed and complex multi-axis systems.

Specification

Advantages

Load Capacity & Precision
KGG ZR Actuator, utilizing a precision ball screw mechanism, is engineered for exceptional accuracy and reliable performance in compact automation. Its design ensures zero axial clearance, which is critical for high-repeatability applications. While optimized for moderate loads, the actuator delivers smooth and precise linear thrust, making it ideal for applications where precise positioning and controlled movement are paramount over extreme load capacity. The integrated encoder provides closed-loop feedback, enabling real-time monitoring and correction to maintain consistent performance and repeatability throughout its long service life.
 
Compact Design & Flexibility
A key advantage of KGG ZR Actuator is its highly compact and lightweight direct-drive design. It integrates a hollow shaft motor, ball screw, and ball spline into a single, space-saving unit. This hollow shaft design not only reduces the overall size and weight but also provides through-hole functionality, allowing for the passage of cables, lasers, or suction lines (hollow adsorption). This offers unparalleled flexibility for creating complex multi-axis systems and simplifies machine design. The compact profile enables high-density installation, maximizing workspace utilization in confined environments such as inside demo machines or multi-axis gantries.

Smooth Performance & Control

KGG ZR Actuator is built for operations requiring low noise and high smoothness. The ball screw mechanism, combined with an encoder closed-loop structure, guarantees stable and jitter-free motion. Furthermore, it supports precise pressure control, enabling "copy" functions where the actuator can adapt to varying surface heights or apply a consistent force, which is essential for delicate assembly, testing, and handling tasks.
 
Application
Semiconductor and electronics manufacturing (LED handling, IC chip adjustment, mobile phone lens assembly and labeling). Precision assembly and testing workstations. Multi-axis gantry and Cartesian coordinate robots. Laboratory automation and medical device handling. Any application demanding a compact footprint, high precision, and integrated hollow shaft functionality.
