❓ Frequently Asked Questions (FAQ)

What are planetary roller screws?

This is an advanced type of linear actuator that uses multiple rollers instead of balls to transmit force between the screw and nut. This design significantly increases load capacity, rigidity, and service life.

What is the main difference compared to ball screws?

The main difference lies in the load transfer mechanism. Rollers provide a larger contact area than balls, resulting in higher load capacity, rigidity, accuracy and longer life for a comparable size.

What applications are these screws best suited for?

They are ideal for applications requiring high accuracy, rigidity, load capacity and long service life, such as industrial robots, CNC machines, positioning systems in the space and aviation industries, medical devices and general high-precision automation.

What is the typical lifespan of planetary roller screws?

The service life of planetary roller screws is generally significantly longer than that of ball screws, often several times longer. The specific service life depends on load, speed and lubrication conditions, but they are designed for extremely long-term operation.

Do they require special maintenance?

Like other precision mechanical components, they require regular lubrication and inspection, but due to their robust design and low wear, their maintenance is generally less frequent and demanding than other systems.

Can they work in harsh environments?

Yes, their robust construction and sealing capabilities make them suitable for a wide range of industrial environments, including those with high dust, vibration or fluctuating temperatures. However, it is always necessary to check the specific specifications and material design for the application.
