智能传动系统供应商赛里斯完成数千万人民币A轮融资，东方嘉富领投

Core Viewpoint - Recently, Hefei Sairis Intelligent Transmission System Co., Ltd. completed a multi-million RMB Series A financing round, led by Dongfang Jiafu and followed by Jiayi Venture Capital, with Dianshi Capital serving as the exclusive financial advisor. The funds will primarily be used for the large-scale production capacity construction of ball screws and planetary roller screws, new product development, and expanding market applications in strategic industries such as humanoid robots and automotive [1]. Group 1 - Sairis, established in 2021, is a global supplier of intelligent transmission systems, focusing on the R&D, production, and sales of high-precision screws and related mechatronic components. The company has built a product matrix centered on "micro ball screws + planetary roller screws" and has extended into linear modules and servo cylinders [1]. - The company has a wide customer base covering various high-end precision transmission scenarios, including laser cutting, 3C electronics, semiconductors, medical devices, humanoid robots, welding robots, and automotive [1]. - High-precision micro ball screws and planetary roller screws are core components that require high standards in materials, design, heat treatment, composite processing technology, molds, and equipment, necessitating long-term dedication to establish system-level know-how and product competitiveness, which has historically been dominated by foreign manufacturers [1]. Group 2 - Sairis has established significant core technological barriers, achieving domestic leading C0-level precision in the high-precision micro ball screw field, with a repeat positioning accuracy of ±0.0003mm, providing critical support for precision motion control in high-end equipment, and leading the domestic market share [2]. - In the planetary roller screw field, the company pioneered cold rolling technology, significantly reducing production costs while greatly shortening delivery cycles [2]. - The company has self-manufactured core equipment, including CNC external thread grinding machines, CNC internal thread grinding machines, CNC rolling machines, testing instruments, and rolling molds, creating a vertical chain from process to equipment to support high consistency and scalable delivery [2].
