In the fields of precise optical testing, industrial automation, semiconductor equipment, laser applications and scientific research experiments, an electric rotating table with large load capacity, high precision, low back emf and multiple installation methods is the core equipment that ensures system stability, precise positioning and long-term reliability. The Sefan Optoelectronics 7SRA1100 electric rotating table, with its precise worm gear and worm wheel + bearing steel shaft system + omnidirectional installation design, integrates advantages such as high load-bearing capacity, high rigidity, low noise and easy maintenance, and can easily cope with harsh conditions such as heavy load, long-term operation and multi-attitude installation. It has become the "all-round" precision rotating solution for industrial and scientific research scenarios. 

Precise transmission, low backlash and high rigidity, precise and smooth rotation

The core of 7SRA1100 adopts a precision shaft system made of bearing steel + hardened and matched worm gear pair. It undergoes precise grinding and backlash elimination processing. The backlash is extremely small, the transmission rigidity is strong, and the operation is smooth without any jamming. The unique gap adjustable design can conveniently compensate for the wear caused by long-term use. It only requires simple tools to complete maintenance, significantly extending the equipment's service life and maintaining long-term stability of accuracy as before. It is equipped with an imported high-quality elastic coupling to connect the motor and the worm. The transmission is synchronous, shock absorption and noise reduction are achieved, the operating noise is extremely low, and it meets the quiet operation requirements of laboratories and clean workshops. 

The outer edge of the tabletop is laser-etched with precise scale marks, which can rotate relative to the tabletop, facilitating initial positioning and providing intuitive reading. The center hole and the rotation center are strictly aligned, with precise diameter tolerance control, ensuring accurate installation positioning. It supports 360° continuous and seamless rotation, with smooth forward and reverse switching, a wide speed adjustment range, capable of achieving micron-level angle fine-tuning at low speed and micro-motion, as well as large-range rotation at medium speed and high speed, maintaining stability in both cases, and meeting the needs of adjusting angles in multiple angles and various working conditions. 

Full-directional overload installation, sturdy and durable, suitable for various working conditions

The body is made of high-strength aluminum alloy and bearing steel, and undergoes hard anodizing treatment. It is dust-proof, corrosion-resistant, vibration-resistant, and resistant to deformation. It can operate stably for a long time in complex environments such as laboratories, laser workshops, semiconductor clean rooms, and automated production lines. With an extremely large load-bearing capacity, it can smoothly bear heavy optical lenses, large workholding fixtures, precision inspection equipment, industrial modules, etc. When fully loaded, there is no shaking or deviation, and from the hardware level, it completely eliminates data deviations and operational errors caused by load vibration. 

The omnidirectional installation design is a prominent feature of the 7SRA1100 - in addition to the standard horizontal installation, it also supports vertical, inverted, and other various installation postures, suitable for unconventional installation positions such as equipment racks, cantilevers, and the sides of work tools, with extremely strong scene adaptability. The base is widened and reinforced, with standard installation holes reserved, ensuring stable placement without the risk of tipping over, and the installation is convenient, without the need for complex adapter components, significantly shortening the equipment integration and debugging cycle. 

Intelligent control, easy integration, suitable for automation and research needs

Equipped with high-performance stepper motors, standard DB9 interface, compatible with Sifan 7SC series motion controllers, supports computer-based upper-level programming, manual point control, origin return, limit protection, multi-axis linkage. It can be quickly integrated into the automation system to achieve process-oriented and intelligent angle adjustment. Servo motors can be replaced for industrial-grade high-precision and high-response requirements, further improving control accuracy and operational stability. An option for photoelectric zero position can be selected to achieve precise origin positioning, meeting high-precision repetitive positioning scenarios.
