Low-Outgassing Bearings for Space Applications

Low-outgassing bearings are essential components for spacecraft, satellites, scientific instruments and all systems operating in the vacuum of space. These bearings are engineered to maintain stability, reduce contamination and offer reliable performance where conventional bearings fail. We supply a wide range of high-precision bearings suitable for space missions and extreme vacuum environments, with worldwide delivery available.

What Makes Low-Outgassing Bearings Special?

In space environments, traditional lubrication and standard bearing materials can release gas particles, which leads to contamination, reduced performance and potential failure of sensitive instruments. Low-outgassing bearings are designed to minimise these emissions through carefully selected materials, coatings and lubricants. They offer long-term stability, high durability and minimal particle generation.

• Low particle emission for vacuum environments
• Special lubricants such as PFPE or dry-film lubrication
• Precision manufacturing for high stability and minimal friction
• Corrosion-resistant and temperature-stable materials
• Suitable for zero-gravity and extreme temperature variations

Applications in Space Technology

Low-outgassing bearings are used in numerous space-related applications, from large satellite mechanisms to delicate optical instruments. Their construction ensures smooth, stable operation even under extreme conditions.

• Satellite positioning systems
• Reaction wheels and gyroscopes
• Solar array drives
• Robotic arms and mechanical actuators
• Vacuum pumps and scientific instruments
• Telescope mechanisms and optical assemblies

Available Types of Bearings

Different space systems require different bearing types. We provide a complete range of low-outgassing bearing solutions tailored to aerospace requirements.

• Hybrid ceramic bearings
• Full ceramic bearings (Si₃N₄, ZrO₂)
• Precision deep groove ball bearings
