Swiss specialist in planetary roller screws used in high load humanoid linear actuators.
Rollvis is a Swiss manufacturer of high-performance roller screws for demanding applications in industry, aerospace, defense, energy, and medical systems. The company is relevant to robotics because planetary roller screws are a key building block in high-load linear actuators, including some humanoid and advanced robotic architectures.
Rollvis presents multiple product families including planetary, inverted, recirculating, and differential roller screws. The breadth of that lineup matters for robotics because different actuator architectures need different screw formats and performance tradeoffs.
On its official site, Rollvis says it has been manufacturing high-performance roller screws since 1970. That long specialization gave the company a durable position in precision linear-motion systems long before the current humanoid cycle.
In the 2020s, Rollvis is increasingly relevant to advanced robotics because planetary roller screws are used in high-load linear actuators, including some humanoid designs. Roboticos dataset tracks the company for that upstream supply-chain role rather than as a robot OEM.

Rollvis is part of the hidden machinery behind modern robots rather than the visible robot layer. Its contribution is in precision linear motion, where roller screws can offer the load capacity, rigidity, and compact force transmission needed for more demanding electromechanical systems.
