During the processes of optical scanning, sample positioning, device alignment, and automated optical path setup, long travel displacement often encounters challenges: high-speed reciprocating motion lead screws are prone to loosening, vertical installation is prone to stalling and slipping, and repeated positioning in multiple batches has deviations. Many translation stages are only suitable for horizontal placement, and the vertical working condition accuracy significantly decreases, causing many troubles in experimental debugging and equipment integration. The 7STA01B series of electric translation stages from Saifan Optoelectronics, with ball screw transmission and both ends supported linear guide rail architecture, cover multiple specifications of travel ranging from 50 to 300mm, are specifically adapted for long-distance reciprocating motion, and also excellently support vertical posture installation, providing a highly reliable linear displacement solution for scientific research and industrial equipment.

The core drive unit of 7STA01B adopts imported high-quality ball screws and is equipped with a three-bearing fixed + shaft-end locking structure. This design effectively prevents the screw from loosening mechanically, ensuring the stability of the transmission even during long-term high-speed reciprocating operation. The positioning accuracy can reach ±1μm, and the positioning error is controlled within ±5μm. Multiple round-trip scans will not show significant drift, thereby ensuring the data consistency of spectral mapping and point-by-point testing of samples. Beijing Saifan Optics... 。
The guide rail adopts a design of being supported at both ends and suspended in the middle with precision linear bearings. It moves smoothly with low resistance. Different from ordinary sliding tables, it can still move smoothly in the vertical installation condition without getting stuck or having obvious degradation in accuracy. This is very helpful in solving the common problems of falling and stalling in Z-axis elevation applications.

This design avoids the vibration and shock caused by rigid connections, reducing the interference of vibration on the optical signal during optical path testing. The equipment is equipped with a manual handwheel, which allows for direct manual movement of the tabletop even when the power is off. This facilitates coarse adjustment of the optical path and prototype debugging, meeting both the requirements of automation and manual debugging. Beijing Saifan Optics... 。
The hardware protection and limit design are well-structured. At both ends of the platform, zero position switches and positive/negative limit switches are integrated. When the machine is powered on, it can automatically return to zero, and at the same time, it achieves hard limit protection, effectively avoiding the risk of overtravel damage. Standard M6 threaded installation holes are reserved on the tabletop. The base also has threaded holes and through holes, which can be directly fixed on the optical platform or stacked to form a XY two-dimensional platform, quickly building a two-dimensional scanning system. The standard configuration includes a stepper motor and a DB9 communication interface. It can directly connect to the Sefan 7SC series motion controller and supports point motion, continuous scanning, and reciprocating sequence programming. According to project requirements, a servo motor can also be installed to further enhance speed and heavy-load capacity, suitable for industrial automation scenarios. Beijing Sefan Optics... 。
The body is made of high-strength aluminum alloy, with hard anodizing blackening treatment. The structure is highly rigid and has excellent vibration resistance. It is suitable for laboratory clean environments and can also be used for internal integration of industrial prototypes. This series offers multiple standard stroke options, including 50mm, 100mm, 150mm, 200mm, and 300mm, making it convenient for users to select according to the optical path space.
