Gaocheng Office Chair Rotation Tester
Currently, no specific production or supply information regarding office chair rotation testers in the Gaocheng area has been retrieved. However, the general technical details and functions of this equipment can be summarized as follows:
The office chair rotation tester is a core testing device used to evaluate the durability and service life of rotating office chairs. Its primary function is to detect potential issues such as base loosening, bearing wear, and rotational stuttering by simulating long-term rotational movements. During testing, the chair legs are fixed to a rotating disc, and an adjustable load (e.g., 225 pounds) is applied to the seat surface. Some devices support 360-degree or 180-degree rotation tests and can set cycle counts (e.g., over 50,000 cycles) to verify the chair's stability during long-term use.
The equipment's technical parameters adhere to international standards, such as those from the United States (BIFMA), QB/T 2922-2007, and BIFMA 5.1-2017. Key parameters include rotating disc diameter (e.g., 770mm), test speed (adjustable from 6 rotations per minute), seat height (adjustable from 350 to 600mm), and applied load (adjustable to 225 pounds). Some models come with additional features like USB data output, power-failure memory, fault alarms, and employ touchscreen and PLC control systems to enhance operational convenience and data recording accuracy.
For specialized evaluation of the base's edge area, some testers (e.g., office chair base rotation life testers) can simulate rotational movements under eccentric loads, applying specific radial pressures (e.g., 1000 Newtons) and recording torque changes, pressure fluctuations, and deformation data to assess load-bearing capacity, structural deformation, and material fatigue. Such tests help optimize base design and prevent fracture risks caused by long-term eccentric use.
Common models on the market include LT-JJ06 (Dongguan Lituo Testing Instruments Co., Ltd.), HD-104 (Guangdong Haida Instruments Co., Ltd.), and KJ-5101 (Dongguan Kejian Testing Instruments Co., Ltd.). The equipment frames are mostly made of aluminum profiles, with seat surfaces adjusted via air cylinders and equipped with force sensors and fixtures to ensure accurate test data.
For specific supplier or custom equipment information in the Gaocheng area, it is recommended to contact local testing instrument manufacturers or consult industry directories for more precise localized services.
