The Toyo GTH series is a built-in rail ball screw module and an upgraded version of the brand's classic ETH series. It includes multiple single-axis models such as GTH4, GTH5, GTH8, and GTH12, as well as dual-slider models like GTH4D and GTH5D. With advantages such as high precision and high rigidity, it is widely used in the field of industrial automation. Below is a detailed introduction:
Adopting a built-in rail design, the rail is embedded into the main body and then ground. The linearity of travel parallelism can reach ±0.02mm, and the repeat positioning accuracy can be stably maintained at ±0.005mm, meeting the needs of high-precision operations. Meanwhile, the main body and slider are made of integrally formed steel, which solves the problem of insufficient rigidity of traditional aluminum sliders and improves the stability of the module during operation.
The special steel belt structure design reduces dust generation during operation, making it suitable for harsh environment scenarios such as clean rooms. The entire series supports external oil injection, allowing maintenance to be completed without disassembling the slider cover and steel belt, which reduces maintenance costs and downtime.
The module width has been optimized for a smaller volume, saving equipment installation space. During installation, there is no need to disassemble the steel belt, and it can be fixed both upward and downward. In addition, the bottom of the main body is equipped with standard positioning pin holes, and the side is added with an installation reference bearing surface, which greatly simplifies the assembly process and improves installation efficiency.
It can be matched with servo motors of multiple brands such as Mitsubishi, Panasonic, and Yaskawa. There are various motor installation methods including exposed, left-folded, right-folded, and downward-folded, which can adapt to different equipment layout requirements. In addition, some models support customized screw leads, covering a variety of specifications from 2mm to 32mm to match different speed requirements.
It is mainly used in processes such as work positioning, clamping, handling, and plug-in in automated production, and is applicable to scenarios such as electronic component assembly, circuit board and wafer cassette positioning and insertion. At the same time, its high-precision characteristics can also meet the supporting needs of higher-precision equipment such as metrology and laser scanning, and is suitable for multiple industries including electronic manufacturing and precision machinery.
