CHUAN HONG released the reduced-stroke planetary roller screw, a revolutionary invention in gear manufacturing

With over 40 years of experience in the R&D and manufacturing of planetary roller screws, Chuan Feng Precision Tools, a leading manufacturer of linear transmission, launched the innovative "Reduced-stroke Planetary Roller Screw" at 2025TIMTOS (Taipei World Trade Center Hall 1, A0905). The product features high load, high speed ratio and lower lead transmission, which is a revolutionary invention in gear manufacturing and has received pre-orders from global manufacturers including humanoid robots and electric vehicle brake systems.

The "Reduced-stroke Planetary Roller Screw" innovatively invented by CHUAN HONG Precision Tools cannot be found in current industrial literature. The proprietary name "reduced-stroke planetary roller screw" was also directly named by CHUAN HONG Precision Tools' founder and chairman Wu Sangui based on its function. The product adopts a large pitch and low lead approach, which solves the traditional industry problems of large pitch and high lead (moving too fast) and small pitch and low lead (load too low). It has currently passed multi-national new patents and applied for PCT international patent protection.

What attracts the most attention from buyers at 2025TIMTOS is that CHUAN HONG Precision has upgraded its R&D and production technology and invented and developed a "reduced-stroke planetary roller screw", which has a powerful deceleration function that can increase the lead from 24mm to 2.5mm at the same pitch. Currently, all electric cylinders on the market require a reducer, but this invention has been tested and no longer requires a reducer. The market believes that this invention will have the opportunity to replace the application of differential planetary roller screws and circulating planetary roller screws, and become a shining star in the linear transmission industry.

It is worth mentioning that CHUAN HONG Precision started out with threaded bolt gauges and ring gauges, and has established an authoritative position in the global industry. It is world-renowned for the production of threaded bolt (ring) gauges, special screw taps for internal and external threaded sheet metal cutters, tooth plates and tooth wheels, etc. It caters to industry needs and has successfully transformed and upgraded the company, developing planetary roller screws to supply the market. The product has a minimum diameter of 8mm and a lead of 0.5mm, and a maximum workpiece diameter of 120mm and a lead of 50mm. It also launched a conversion-grade workpiece with a length of up to 6M. The function and benefits of this product can replace ball screws, hydraulic cylinders and pneumatic cylinders. It is widely used in industrial equipment and has a high CP value.

CHUAN HONG precision planetary roller screws have the characteristics of high linear motion accuracy, high rigidity, high output, long life, high load, low backlash, low noise, precise positioning, etc., and have a shorter lead. Planetary roller screws do not require a reflux device, can achieve faster speeds than ball screws, and reduce noise levels. With the technologies of Industry 4.0 and Industrial Internet of Things (IIOT), it has been widely used in the precision machinery industry. In addition to all-electric plastic injection molding machines, servo punching machines, folding machines, broaching machines, and 3D printing, it is also suitable for high-speed, high-load, and high-precision mechanism applications such as humanoid robots and electric vehicles.
