Why Traditional Roller Screw Suppliers Are Failing You
In 2026, with supply chain disruptions hitting 68% of US manufacturers (per Deloitte 2025 report), your operations can't afford downtime. Here's what you're facing:
- High Prices: Overseas suppliers charge 30-50% premiums without justifying value, eating into your ROI.
- Low Quality: Ball screws fail under high loads, causing 37% more breakdowns in heavy-duty apps.
- High Shipping Costs: Delays average 45 days from Asia, inflating logistics by 25% amid global freight hikes.
- Inconsistent Precision: Backlash and wear reduce accuracy to ±0.05mm, unacceptable for aerospace or medical devices.
- Limited Customization: No OEM/ODM options force redesigns, adding 20% to project timelines.
- Poor After-Sales: No local support means weeks of downtime per failure.

Technical Specifications: Planetary Roller Screw Excellence
Roller screws, especially planetary types, use caged rollers for superior load distribution. Unlike ball screws, they offer zero backlash, high rigidity, and micronic repeatability (±0.001mm). Ideal for high-force, high-speed apps.
| Model | Nominal Dia. (mm) | Lead (mm) | Dyn. Load (kN) | Stat. Load (kN) | Max Speed (rpm) | Accuracy (μm/300mm) |
|---|---|---|---|---|---|---|
| RSF15 | 15 | 5 | 25.4 | 45.2 | 10,000 | ±3 |
| RSF20 | 20 | 10 | 52.1 | 92.3 | 8,000 | ±2 |
| RSF25 | 25 | 5/10 | 98.7 | 175.4 | 6,000 | ±2 |
| RSF32 | 32 | 10 | 152.3 | 270.1 | 5,000 | ±1 |
| RSF40 | 40 | 10/20 | 245.6 | 436.2 | 4,000 | ±1 |
| RSF50 | 50 | 10 | 389.4 | 692.7 | 3,500 | ±1 |

Note: Custom sizes up to 120mm dia., leads 1-50mm, materials: CF53 steel, 42CrMo, or stainless. Acceleration up to 10g, speeds to 150m/min equivalent.
Performance Characteristics in Depth
YIDI roller screws excel in high axial loads (up to 1000kN static) due to full roller contact, distributing force evenly across 100+ rollers per turn. This yields 3-5x higher rigidity than ball screws, minimizing deflection under 200kN loads to under 0.01mm/m.
Friction coefficient is ultra-low at 0.003, enabling efficiencies >90% and speeds up to 10,000 rpm without heat buildup. Lifetime exceeds 50,000km under C10 rating, per ISO standards—10x ball screw durability in contaminated environments.
Backlash elimination via preloaded rollers ensures repeatability to 1μm. Torque ripple is <1%, critical for servo-driven systems.
Real-World Application Scenarios & Case Studies
- CNC Machining: RSF32 in 5-axis mills handles 150kN thrust, boosting feed rates 40% with ±2μm accuracy. Case: US firm reduced cycle time 25%.
- Industrial Robotics: High-speed arms use RSF25 for 98.7kN loads, enabling 2g acceleration without vibration.
- Aerospace Actuators: RSF40 in flight simulators: 245kN load, MTBF >20,000 hours.
- Medical Equipment: Precision presses with RSF20: sterile stainless, IP65 sealed.
- Defense & Heavy Machinery: Injection molding (500-ton): RSF50 cuts energy 15%.
