In the high-speed feed of laser welding, at the precise detection station of semiconductor wafers, and in the heavy-load displacement section of the automated production line, "achieving both heavy-load and high-precision" has always been the core pain point in the field of precise motion control. Many industrial engineers and researchers have encountered such difficulties: ordinary translation stages have rapid degradation in precision under heavy loads, and after several high-speed reciprocating runs, the screws become loose. When building multi-axis combinations, the compatibility is poor, and after several weeks of debugging, the expected results are not achieved. After 22 years of deep research in the field of precise motion control, Sevan Optoelectronics has iteratively upgraded based on the core needs of medium and heavy-load scenarios, and匠心crafted the 7STA04B series of electric translation stages. With the core advantages of "import-grade transmission system + strong rigidity structure + full-scenario adaptability"， it redefines the domestic benchmark for medium and heavy-load displacement control， injecting stable and reliable power into industrial manufacturing and scientific research innovation. The core transmission system is imported， and even under heavy loads， it still maintains micrometer-level precision. In heavy-load scenarios， the most demanding for translation stage performance， the transmission system's stability is the key. The 7STA04B series is equipped with imported high-quality ball screws， combined with exclusive three-bearing installation and shaft end locking structure， fundamentally eliminating the common problem of screw loosening in high-speed reciprocating motion. The repetitive positioning accuracy is up to ±0.003mm， and the positioning error is controlled within ±0.005mm， even with a full-load of 50kg， it can still maintain micrometer-level positioning consistency. It is equipped with a supporting type precision linear bearing guide rail that is rigidly connected to the whole and the base plate， ensuring smooth and uninterrupted movement throughout the process. It can effectively disperse the local pressure caused by heavy loads and can independently complete medium-load displacement tasks with a single axis， or support multi-axis combination to build complex motion systems. The stepper motor is synchronized with the ball screw through an imported high-quality elastic coupling， not only controlling the running noise below 45dB， but also achieving transmission without delay. From the laser welding feed of new energy vehicle components to the smooth movement of large-sized workpieces， every action is precisely controllable， completely eliminating the old problem of "shaking when moving， floating under heavy loads" of traditional translation stages. The strong rigidity and durable structure can operate stably in complex working conditions in industrial workshops. Dust and oil pollution in the workshop and frequent reciprocating operations put nearly harsh requirements on the structural rigidity and durability of the translation stage. The 7STA04B series adopts a high-strength aluminum alloy body， which is precisely processed and anodized， balancing lightweight and high rigidity. Under a maximum load of 50kg， the surface jump is still less than 1μm， perfectly solving the industry problem of structural deformation under heavy loads. Zero position and limit switches are built in at both ends of the body， which not only facilitate quick and accurate positioning but also effectively avoid mechanical damage caused by exceeding the travel limit. It provides comprehensive protection for equipment and workpiece safety. The optimized dust-proof protection design can effectively isolate dust and oil pollution in the industrial environment， achieving 30，000 hours of trouble-free operation in complex workshop conditions. The lifespan of core components is 50% higher than the industry average， significantly reducing equipment maintenance costs and unplanned downtime losses， making the production line operation more worry-free. Modular flexible adaptation， seamless integration in all scenarios. No worries. Many equipment integration engineers have had similar experiences. After a new translation stage arrives， it takes a lot of time to modify the holes， adapt interfaces， etc.， seriously delaying the project delivery progress. The 7STA04B series adopts a fully modular design， with a travel range of 50mm-500mm for all specifications. Standard pitch threaded holes and through holes are evenly distributed on the table and base， supporting horizontal， vertical， and inverted installation methods， and can be easily integrated into various equipment such as laser welding machines， automated inspection lines， multi-axis scientific research experimental platforms， etc. The equipment is equipped with DB9 standard interface, which can directly connect to the Sefan 7SC series motion controller. It is perfectly compatible with mainstream programming environments such as LabVIEW and Python. It supports complex motion modes like point storage and uniform scanning, and can be quickly debugged without requiring profound professional programming knowledge. It also supports on-demand replacement of servo motors and upgrading to high-speed heavy-load configurations, easily meeting the needs of various scenarios ranging from basic scientific research experiments to large-scale industrial production. The system integration time is directly shortened by 40% compared to similar products. As a benchmark product in the field of domestic precision motion control, the 7STA04B series has passed the ISO9001 quality system certification. Core components are provided with a 3-year warranty, and the response time for after-sales service is ≤ 4 hours. With its outstanding cost-performance advantage, its total life cycle usage cost is 35% lower than that of imported brands. Now, it has been widely applied in laser processing, semiconductor packaging, automated production lines, university research laboratories, and many other fields: firmly maintaining positioning accuracy in new energy vehicle component welding, achieving ultra-smooth displacement in wafer inspection equipment, supporting cutting-edge research on multi-axis experimental platforms in top universities, and becoming the trusted choice for countless research institutions and manufacturing enterprises. Heavy-duty stable movement, micrometer precision control. The Sefan Optoelectronics 7STA04B series electric linear translation stage is refined with 22 years of technical accumulation in every detail, making each linear movement a double guarantee of precision and efficiency, helping domestic precision equipment break through in the global market.
