Standard Planetary Roller Screw By-Product Series |
The biggest technical feature of the Standard Planetary Roller Screw Series is its stable and fixed roller motion trajectory. During operation, the planetary rollers conduct dual movements of self-spinning and orbital revolution around the screw shaft, while maintaining zero axial displacement relative to the nut. This non-recirculating fixed-axis structure avoids dynamic position deviation caused by roller axial movement, ensuring extremely high motion stability and repeated positioning accuracy during long-term cyclic operation.
Compared with recirculating planetary roller screws that feature axial cyclic roller movement and reverse planetary roller screws with zero displacement relative to the screw shaft, the standard type boasts a simpler and more mature mechanical structure. Its fixed roller layout enables even load bearing across all thread contact surfaces, effectively reducing local wear and mechanical fatigue. With reliable meshing precision and stable transmission efficiency, it minimizes equipment jitter and position errors, achieving outstanding durability and operational consistency under continuous fixed-stroke linear motion scenarios.
Benefiting from its ultra-stable transmission performance, fixed precision trajectory and long service life, the Standard Planetary Roller Screw Series is widely used in various industrial equipment requiring stable and accurate linear reciprocating motion. It is perfectly suitable for precision automation actuators, heavy-duty mechanical lifting systems, industrial machine tool feed mechanisms, precision testing and inspection equipment, and automated production line positioning devices. In addition, it serves as a core transmission component for aerospace auxiliary machinery, new energy industrial equipment and general heavy-duty servo linear motion systems, covering most conventional precision linear drive scenarios.
Our technical team conducts targeted R&D and structural optimization based on the motion principles of standard planetary roller screws. By analyzing the mechanical differences between standard, recirculating and reverse roller screw structures, we optimize the thread tooth profile, roller matching tolerance and planetary motion coordination mechanism. The fixed-axis non-displacement operation principle is precisely calibrated to ensure stable roller revolution and autorotation without axial offset.
All products comply with international industrial precision standards, and each batch undergoes strict performance tests including motion trajectory detection, positioning accuracy calibration, load stability testing and fatigue life verification. The team supports personalized parameter optimization and size customization according to customer working conditions, providing targeted standard planetary roller screw transmission solutions for diverse industrial equipment.
The Standard Planetary Roller Screw Series adopts high-precision CNC thread grinding and finishing technology. The screw shaft and planetary rollers feature precise tooth profile machining and surface hardening treatment, ensuring accurate thread meshing, low friction and uniform force bearing. The standardized assembly process strictly controls roller clearance and planetary motion accuracy, maintaining the core advantage of zero axial displacement of rollers relative to the nut.
We implement standardized modular production for the standard planetary roller screw series, with complete production processes and strict quality inspection systems. Conventional standard models are in stock for fast batch delivery. For customized non-standard specifications, we adopt flexible production scheduling to shorten delivery cycles. All finished products pass full pre-shipment inspections to ensure stable quality, providing cost-effective and high-reliability linear transmission components for global industrial customers.
