Easily achieve the movements of "grasping, opening and closing, and left-right symmetry."
The THK electric actuator Compact Series KR-RL is an LM guide actuator that employs left and right screws in the KR model. By using a single motor to perform the symmetrical "open" and "close" movements, it enables a wide range of applications such as gripping, measuring, and positioning. Additionally, its four-direction load structure allows for use in any orientation. The modular design significantly reduces the number of components in the product, streamlining procurement, delivery management, design, and assembly processes, which shortens the lead time to complete the equipment. As a result, it is utilized in various devices, including robot arm end effectors, screw tightening machines, cutting devices, and dispensers. Furthermore, the related links provide more detailed product descriptions, product catalogs, user manuals, 2D and 3D CAD files, selection materials, and a wealth of technical information.

basic information
■Features - Simultaneous drive with left-right symmetry on a single axis By adopting a screw shaft that can be driven symmetrically left and right, opening, closing, and gripping can be achieved with a single motor control, resulting in labor-saving efficiency. - Contribution to labor reduction and space-saving through modular structure The KR-RL type with a modular structure has fewer parts compared to component products, reducing the labor required for the assembly of the drive unit. Additionally, the advantage of simultaneous left-right symmetrical drive on a single axis allows for the replacement of multi-axis component products with a simpler single-axis modular product, contributing to space-saving. - Optimal for end effectors with a four-direction equal load structure The structure can withstand loads from four directions (radial, reverse radial, and lateral), allowing for assembly without being constrained by the mounting position. For example, it is ideal for end effectors of robotic arms that perform complex movements, featuring high rigidity that can tolerate moments in an overhang state when holding heavy or complex-shaped workpieces.
