You know the frustration: planetary roller screw failures that halt production lines, skyrocket maintenance budgets, and erode your ROI.
- High Prices from Premium Suppliers: Imported screws cost 30-50% more, squeezing margins without proportional reliability.
- Low Quality from Offshore Chains: Inferior materials lead to 37% higher failure rates within 12 months (industry data from NSK reports).
- Excessive Shipping Delays: Weeks of wait time from distant factories disrupt your supply chain, causing 20% downtime losses.
- Inadequate Load Handling: Ball screws buckle under heavy dynamic loads, risking catastrophic failures in CNC or robotics.
- No Customization: Off-the-shelf options ignore your OEM needs, forcing compromises on precision and speed.
- Post-Sale Nightmares: Poor service leaves you stranded with non-compliant parts for US regs like RoHS.
Imagine slashing these pains. Discover YIDI's solution below.
YIDI Motion's Planetary Roller Screws: Engineered for US Demands

- Quality Assurance: ISO 9001 certified, zero defects policy with advanced metrology.
- OEM/ODM Design: Custom leads, diameters tailored to your specs – from prototype to volume.
- High-Speed Delivery: 7-14 days to USA ports, beating competitors by 50%.
- Cost Savings: Direct from Hebei factory – 30% lower than EU/US brands.
- Longevity: Rated for 100 million cycles, reducing TCO by 40%.
Detailed Technical Parameters
Planetary roller screws excel in high load capacity (up to 500kN dynamic), rigidity (3-5x ball screws), and speeds (up to 200m/min). Here's a comprehensive spec table for easy integration into your designs:
| Model | Nominal Dia. (mm) | Lead (mm) | Dyn. Load (kN) | Stat. Load (kN) | Max Speed (rpm) | Efficiency (%) |
|---|---|---|---|---|---|---|
| PRS-20 | 20 | 5 | 45 | 70 | 5000 | 90 |
| PRS-32 | 32 | 10 | 120 | 200 | 4000 | 92 |
| PRS-50 | 50 | 10 | 280 | 450 | 3000 | 93 |
| PRS-63 | 63 | 16 | 420 | 650 | 2500 | 94 |
| PRS-80 | 80 | 20 | 500 | 850 | 2000 | 95 |

Note: Custom sizes up to 120mm dia. available. All comply with RoHS, CE, and US import standards.
Performance Characteristics Deep Dive
The planetary roller screw mechanism uses 6-12 rollers in planetary motion, distributing loads evenly for superior rigidity. Unlike ball screws (prone to brinelling), rollers handle shock loads 3x better. Acceleration up to 10g, backlash <0.005mm.
Stroke life calculation: L = (C_dyn^3 * f) / F_a^3 (ISO 3408-5), where our C_dyn ratings ensure 10x ball screw life in high-cycle apps.
Real-World Applications & Case Studies
- CNC Machining: PRS-50 reduced vibration by 25%, boosting throughput 15% for a Texas fabricator.
- Robotics: High-speed PRS-32 in arms handles 200kg payloads at 2m/s.
- Injection Molding: 40% faster cycles with PRS-63, per DuPont-like client.
- Aerospace Actuators: MIL-spec precision, zero failures in 5 years.
