Lead: As the core built-in rail module of Toyo, this series offers a rich selection of lead specifications. The GTH4 model is available with leads of 2/6/12 mm; the GTH5 model provides multiple options of 2/5/10/20 mm. Different leads correspond to different operating speeds. For example, the GTH4 with a 2 mm lead achieves a maximum speed of 100 mm/s, while the version with a 12 mm lead can reach up to 600 mm/s.
Rigidity: The module adopts an integrally formed steel structure for both the base and slider, solving the problem of insufficient rigidity in traditional aluminum sliders. Combined with the process of embedding and grinding the rail into the base, the running parallelism accuracy reaches ±0.02 mm. This not only ensures operational stability but also enables the module to withstand a certain load without deformation in scenarios such as positioning and handling.
Lead: As an upgraded low-profile version of the GTH Series, it features the same lead configurations as the corresponding GTH models with no difference in core functions, making it suitable for applications requiring a lower installation height.
Rigidity: It inherits the built-in rail structure and retains the rigidity-enhanced characteristics. Meanwhile, on the basis of maintaining high rigidity, the material is optimized to reduce the aluminum usage of the base, achieving a lightweight design that balances rigidity and installation convenience. With a repeat positioning accuracy of ±0.005 mm, it is ideal for precision clamping and electronic component assembly scenarios.
Lead: This is a dedicated built-in rail ball screw module for cleanroom environments. Taking the GCH4 model as an example, the ball screw leads are divided into three grades: 2/6/12 mm, corresponding to maximum speeds of 100/300/600 mm/s respectively, which meets the high-precision transfer requirements in cleanrooms.
Rigidity: It also adopts an integrally formed steel structure, offering higher rigidity than traditional aluminum modules. Equipped with a high-precision ball screw drive and featuring a repeat positioning accuracy of ±0.005 mm, it can maintain stable operation even under a horizontal load of 25 kg and a vertical load of 8 kg, avoiding positioning deviations caused by insufficient rigidity.
Lead: Represented by the ETH14 model, the ball screw covers leads of 5/10/20/32 mm. The 32 mm large-lead version can reach a maximum speed of 1600 mm/s. However, a larger lead results in lower rated thrust—the 32 mm lead version has a rated thrust of 218 N, making it suitable for high-speed and light-load scenarios.
Rigidity: Adopting a dual linear guide rail design, it has better rigidity than single-rail structures. It can meet the medium-to-heavy load positioning needs of industries such as automotive and electronic manufacturing, with a maximum horizontal load capacity of 110 kg. Even when operating within this load range, it can maintain a repeat positioning accuracy of ±0.005 mm, demonstrating strong deformation resistance.
Lead: Designed for cleanroom applications, taking the ECH22 model as an example, the ball screw offers various lead specifications of 5/10/25/40 mm. The large-lead versions (25/40 mm) are suitable for high-speed transfer scenarios in cleanroom environments.
Rigidity: Although it focuses on cleanroom design, it does not compromise rigidity performance. By optimizing the assembly accuracy of the guide rail and base, it ensures the structural stability of the module when bearing vertical and horizontal loads in precision scenarios such as medical testing and semiconductor equipment, meeting the operational requirements of nanometer-level accuracy.
In addition, Toyo's belt-driven modules (e.g., the ETB Series) mostly adopt large lead specifications such as 32 mm. However, their overall rigidity is weaker than that of ball screw-driven series, making them more suitable for high-speed conveying scenarios with low rigidity requirements. In contrast, the aforementioned ball screw-driven series are mainstream choices that balance lead flexibility and high rigidity.
