GUREN was established in Shenzhen, focusing on the R&D of electrical slip rings, pneumatic slip rings and fluid rotary unions. A dedicated dynamic-sealing research group was formed at the same time.
The core engineering team was built up, and CAD/CAM design together with precision CNC machining was brought in-house. The product range was extended into mid- and high-end applications such as high-pressure sealing, high speed and extreme media.
Two patent applications were filed covering our pneumatic slip ring sealing structure and integrated rotary joint designs. Products were tested for CE marking according to EMC 2014/30/EU and RoHS.
Both patents were granted on 11 February 2025 (ZL 2024 2 088728.1 and ZL 2024 2 0934491.6). The quality management system was certified to ISO 9001:2015.
GUREN now supplies twelve product series — through-bore, capsule, high-current, fibre optic, pneumatic, fluid rotary union, high speed, high frequency and more — serving wind power, robotics, medical CT, radar, tunnel boring and marine applications.
