Staff Reporter On February 7, 2026, information from the National Intellectual Property Administration revealed that Suzhou Jodell Robot Co., Ltd. has obtained a patent for “An Anti-Creep Guide Rail,” with authorization announcement number CN223881563U and an application date of April 2025 . This patented technology aims to solve the precision loss problem caused by relative micro-displacement (creep) between the slider and base during high-precision linear motion.
The patent abstract indicates that this utility model discloses an anti-creep guide rail, comprising: a base; a first slider capable of linear sliding relative to the base in a first direction; a roller retainer assembly arranged between the base and the first slider, which includes a first retainer body, at least two rows of first rollers arranged in parallel along the first direction, and a first anti-creep unit .
The innovation of this technology lies in its mechanical anti-creep design. Opposite side walls of the first slider and base are provided with first track grooves, and both ends of the first rollers are confined within these first track grooves . More critically, the first anti-creep unit includes a first gear and a first rack. The first gear is axially constrained on the first retainer body and rotates with the sliding direction of the first slider, while the first rack is arranged on the first slider and/or base to engage with the first gear. Importantly, the rolling path of the first gear does not coincide with the rolling path of the first rollers .
In traditional guide rail designs, creep phenomena may occur between the roller retainer and the slider or base during long-term, high-frequency reciprocating motion, affecting motion accuracy and positioning stability. Jodell Robot’s patented technology, through the ingenious design of the gear-rack synchronization mechanism, effectively limits the relative displacement between the roller retainer and the slider, thereby ensuring the accuracy and stability of the guide rail during high-precision motion.
According to public data from Tianyancha, Suzhou Jodell Robot Co., Ltd., established in 2018 and located in Suzhou, is primarily engaged in the general equipment manufacturing industry. The company has a registered capital of 10,752,128 million yuan. Tianyancha big data analysis shows that Jue Robot has invested in 7 enterprises externally, participated in bidding projects 2 times, and in terms of property clues, possesses 37 trademark information items and 127 patent information items, in addition to 8 administrative licenses .
This anti-creep guide rail patent is another achievement in Jodell Robot’s continuous technological accumulation in the field of precision motion control. Together with multiple patented technologies obtained in 2025, such as clamping devices, flat adsorption devices, and high-stiffness linear rotary actuators, it further enriches the company’s intellectual property system in electric servo components and precision actuators.
Industry insiders point out that with the rapid development of embodied intelligence and humanoid robots, the demand for high-precision, high-stability motion control components is growing. Jodell Robot’s anti-creep guide rail technology is expected to be applied in scenarios requiring extremely high positioning accuracy, such as semiconductor processing, precision assembly, and medical equipment, providing more reliable motion control solutions for related fields.
