Koganei Three-Finger Type Linear Guide Specification Mechanical Hands
Manufacturer: KOGANEI CORPORATION
Features
To begin with, these units do not require air piping, making them an excellent solution for areas where air supply lines cannot be installed, such as index tables or compact automated stations. Additionally, the lineup includes three configurations: a standard parallel type, a parallel type with a linear guide specification, and a three-finger version featuring a linear guide design. Moreover, the spring force can be adjusted to either a strong or weak setting, allowing the gripping performance to be tailored to different workpieces. Finally, the linear guide specification incorporates a guide on the lever, ensuring high precision of ±0.01 mm and supporting a long operating life for reliable, consistent performance.
