Many equipment engineers only refer to the overall dimensions when selecting linear modules, ignoring load capacity, rigidity and protection class. This leads to problems such as accuracy drift, abnormal noise and shortened service life in later equipment operation, raising maintenance costs. Several key indicators must be grasped for proper linear module selection.

First, confirm the accuracy grade. Ball screw modules are preferred for precision assembly and semiconductor inspection scenarios, with stable repeat positioning accuracy of ±0.01mm. Medium-precision solutions can be adopted for material handling and ordinary transfer equipment to avoid unnecessary cost waste caused by excessive performance. Steel-based KK modules feature integrally formed steel sliders, which have higher rigidity than ordinary aluminum sliders and resist deformation under lateral loads, making them suitable for heavy-load and high-frequency operations.

Second, calculate the actual load and stroke. Do not merely rely on the maximum rated load from module datasheets. The weight of workpieces and fixtures should all be included in the calculation, with dynamic impact taken into consideration. For long-stroke applications, pay attention to screw deflection of ball screw modules and switch to a proper model when necessary. GTH built-in modules can be selected for equipment with limited space thanks to their compact structure saving installation space.

Third, match the protection structure. Fully enclosed modules are preferred for production sites with heavy dust and metal debris; semi-enclosed modules can meet the requirements for clean indoor laboratories. For vertical mounting applications, ball screw modules have no self-locking capability, so brake motors must be equipped to prevent slider falling and eliminate potential safety hazards.

Original manufacturers can provide technical support for model selection. Green Valley Times Transmission has a complete product portfolio covering transmission components including KK modules, built-in modules and servo electric cylinders, with support for non-standard customization. Fully communicate working conditions and adopt technical recommendations from manufacturers to select linear modules suitable for project requirements.
