As one of the top global planetary roller screw manufacturers, Chuan Hong has redefined gear transmission systems with the groundbreaking Reduction Planetary Roller Screw. Designed to address industry pain points, this new solution combines a large thread pitch with an ultra-low lead, delivering high load capacity without the drawbacks of conventional screw mechanisms.
Unlike traditional solutions, the Reduction Planetary Roller Screw achieves a high reduction ratio while maintaining structural simplicity and durability. This innovation is already being adopted in cutting-edge sectors such as humanoid robotics and electric vehicle (EV) braking systems, where precise control and compact design are critical.
Chuan Hong's patented Reduction Planetary Roller Screw provides substantial reductions in linear movement per revolution—achieving as little as 2.5mm lead from a 24mm pitch—without needing a gearbox. This enables more compact, efficient system designs and simplifies component integration in electric cylinders and automation equipment.
What makes this different from a differential roller screw or recirculating roller screw?
The Reduction Planetary Roller Screw solves both issues with a clean, patented structure that retains high rigidity and performance.
While both recirculating roller screws and differential roller screws aim to deliver fine positioning, their complexity increases the risk of wear, system failure, and high maintenance costs. In contrast, Chuan Hong's Reduction Planetary Roller Screw:
These advantages are why leading planetary roller screw manufacturers are looking to Chuan Hong's innovation as the new standard.
With over four decades of engineering excellence, Chuan Hong has built a global reputation as one of the most trusted planetary roller screw manufacturers. Our R\&D team continues to set industry benchmarks, and our portfolio includes:
We're not just another supplier — we're partners in innovation, helping our clients transition away from outdated differential roller screws and recirculating roller screws toward smarter, more scalable linear motion solutions.
