Original Rollvis Satellite Roller Screw RV/RVR Series - Swiss Precision for Robots

Rollvis SA, headquartered in Geneva, Switzerland, represents the global peak of planetary roller screw technology. Unlike conventional ball screws, Rollvis utilizes "satellite" threaded rollers arranged around the screw shaft to transmit loads. This design geometrically increases the number of contact points, enabling incredible thrust and rigidity within an extremely compact diameter.

Featuring the iconic RV (Standard), RVR (Recirculating), and RVP (Inverted) series, Rollvis offers ultra-fine leads down to 0.25mm and micron-level control precision. For humanoid robot joints and aerospace mechanisms where space is severely limited but multi-ton thrust is required, Rollvis is the ultimate, irreplaceable solution.

Product Highlights

Swiss Precision Engineering: Every screw is precision-ground at the Geneva factory, providing the world's highest class of linear positioning accuracy.
Unmatched Thrust Density: Occupies half the volume of a ball screw while offering 3-5 times the static and dynamic load capacity.
Ultra-Fine Lead Capability: Supports extremely small leads (e.g., 0.25mm, 0.5mm), achieving massive mechanical gain and huge thrust without the need for heavy gearboxes.
High Rigidity & Zero Backlash: Through rigorous preload matching, Rollvis provides nearly infinite transmission rigidity, ensuring instantaneous dynamic response.
Ultimate Reliability & Lifespan: Compared to ball screws, the load distribution is more uniform, resulting in minimal wear even under high-frequency, heavy-duty continuous cycles.
Extreme Environment Ready: Available in full stainless steel or with specialized coatings to handle high vacuum, extreme temperatures, and radioactive environments.

Medical Surgical Robots: Micron-level precision for interventional surgical instruments and Da Vinci robot upgrades
Aerospace: Satellite deployment mechanisms, Fly-by-wire flight control systems, and missile fin actuators
Precision Lab Equipment: High-pressure fluid chromatography and nanometer-level positioning platforms
High-End Stamping/Pressing: Ultra-compact precision servo presses

Frequently Asked Questions

Why is a Rollvis roller screw significantly more expensive than standard screws?

Its manufacturing process is the pinnacle of precision mechanics. Each roller requires precise threading and matching. The resulting thrust density and accuracy are unattainable by ordinary screws, making it the key to breaking "power bottlenecks."

How do you guarantee 100% Swiss origin?

We deal directly with Rollvis SA in Switzerland or their high-end authorized global channels. Each product comes with an original factory inspection certificate and a unique anti-counterfeit code traceable to Geneva.

What is the difference between a Satellite Roller Screw (Rollvis) and a Ball Screw?

Roller screws use "threaded rollers" instead of "balls." The contact area changes from "points" to "lines," drastically increasing load capacity. Without ball recirculation, the operation is also smoother and quieter.

Does it require special lubrication?

Yes. The Swiss factory recommends high-performance synthetic grease. We can recommend the best lubrication scheme based on your specific speed and temperature requirements.
