Simple realization of 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 uses left and right screws in the KR model. By using a single motor to perform the symmetrical "open" and "close" actions, it enables a wide range of applications such as gripping, measuring, and positioning. Additionally, its four-directional load structure allows for use in any orientation. Furthermore, modularization has significantly reduced the number of components in the product, leading to shorter lead times for equipment completion through reductions in procurement, delivery management, design, and assembly labor. As a result, it is adopted in various devices, including robot arm end effectors, screw tightening machines, cutting devices, and dispensers. Moreover, the related links provide a wealth of technical information, including detailed product descriptions, product catalogs, manuals, 2D and 3D CAD files, and selection materials. Please take a look at these as well.

basic information
■Features - Simultaneous drive with left-right symmetry possible on a single axis By adopting a screw shaft that can be driven symmetrically, opening, closing, and gripping can be achieved with a single motor control, resulting in labor savings. - Contributes 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 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-directional equal load structure The structure can withstand loads from four directions (radial, reverse radial, lateral), allowing for assembly without being restricted by the mounting position. For example, it is ideal for end effectors of robotic arms that perform complex movements, providing high rigidity that can accommodate moments in an overhanging state when holding heavy or complex-shaped workpieces.
