Original Ewellix Planetary Roller Screw for Heavy-Duty Robot Linear Actuators

Ewellix (formerly SKF Motion Technologies) leverages over a century of precision engineering heritage to provide the world's highest-performing linear motion solutions. Their Planetary Roller Screws represent the pinnacle of linear drive technology, utilizing multiple threaded rollers instead of balls to transmit power. This design geometrically increases the contact area, providing several times the static and dynamic load capacity of a ball screw of the same size. Ewellix screws are the core components for humanoid robot leg actuators, heavy-duty collaborative robot joints, and "oil-to-electric" (hydraulic replacement) applications in extreme environments.

Product Highlights

Massive Load Capacity: The planetary roller design significantly increases the number of contact points, offering dynamic load ratings far superior to equivalent ball screws.
Ultimate "Oil-to-Electric" Solution: High thrust density allows these screws to replace bulky hydraulic cylinders with more precise, eco-friendly, and maintenance-free electric control.
Extreme Reliability & Service Life: The unique structure minimizes pressure on individual contact points, resulting in minimal wear even under 24/7 high-frequency cycle conditions.
High Speed & Acceleration: Free from the physical limitations of ball recirculation, these screws can operate at extremely high rotational speeds and accelerations without compromising precision.
Harsh Environment Durability: Superior material science and engineering allow stable operation under severe impact, vibration, and extreme industrial or outdoor conditions.
Micrometer Precision Preloading: Advanced preload adjustment technology ensures high rigidity with nearly zero backlash for absolute motion control.

SDM-20-10	20	10	45	28	Automated Assembly Lines

Application Fields

Heavy-Duty/Humanoid Robotics: Leg drive systems, high-load linear push-rods, and powered exoskeletons.
Aerospace: Aircraft flap actuators, satellite payload deployment, and Mars rover robotic arms.
Automotive Manufacturing: Servo welding guns and heavy-duty stamping feed systems.
Injection Molding: Injection mechanisms for all-electric molding machines and die-casting mold control.
Defense Systems: Precision aiming systems, turret rotation, and elevation actuators.

Frequently Asked Questions

Q: How do I choose between a Roller Screw and a Ball Screw?

A: Choose a Roller Screw if your application requires massive thrust (especially shock loads) and has limited installation space. Choose a Ball Screw for general-purpose smooth transmission where cost is a primary concern.

Q: Are the Ewellix products you sell 100% genuine?

A: Absolutely. We provide only original Ewellix products with Swedish factory certificates and unique batch numbers. As mission-critical parts, we prioritize authenticity for safety.

Q: Why is the Ewellix Planetary Roller Screw considered a replacement for hydraulics?

A: Its load density is comparable to hydraulic cylinders, but electric drives offer faster response, higher precision, no oil pollution, and no complex hose maintenance.

Q: Do these screws require frequent lubrication?

A: High-performance screws must remain well-lubricated. Ewellix provides specialized long-term grease. We recommend checking or replenishing every 500-1000 hours under heavy-duty, high-frequency use.

Q: What is the typical lead time?

A: Standard ball screws usually ship in 2-4 weeks. Planetary roller screws, due to their complexity, typically require an 8-12 week custom production cycle.
