How Future Space Tech Uses Vacuum-rated Solutions From Pacific Bearings Industrial
Robot arm, such as canadarm2, uses bearings for smooth and precise attitude control, docking, repairs, etc Ball bearings led the market in 2024 with usd 26.7 billion in revenue. Bearings in space technologies bearings for space applications are small in size but not in importance.
INDUSTRIAL – Pacific Bearings
They will particularly benefit satellites and spacecraft, which need optimal weight capacities in order to perform enhanced flight dynamics and acceleration. The market is segmented based on product types such as ball bearings, roller bearings, and other variants Whether for space exploration, deep space missions, or other precision applications in high vacuum environments, these bearings are specifically designed to offer unmatched performance, reliability, and long service life.
It outlines the challenges bearings face in space environments, such as vacuum, thermal extremes, and contamination, necessitating the use of specialized materials and lubrication schemes
However, machine builders are raising performance requirements of these bearings in additional applications like semiconductor fabrication, aerospace, and processing equipment for medical devices — typically ultraclean and vacuum environments. But how can bearings withstand the vacuums of space, and increasing demand for their use in space applications Satellite bearings are high precision, high reliability products that support a variety of onboard systems such as gyroscopes, antenna pointing systems, positioning mechanisms, and deployment systems In satellite applications, bearings must withstand vibrations and rotate reliably for years in the vacuum of space, and with only small amounts of lubricating oils.
Engineering the impossible from robotic arms performing microsurgery to propulsion systems navigating deep space, bearings remain the unseen yet indispensable drivers of progress As the line between mechanical and digital systems continues to blur, the bearing industry stands on the brink of reinvention. After all, space technologies face a range of challenges that demand precision engineering solutions for optimal performance In addition, some space mechanisms have suffered from premature wear, which can jeopardize the success of a mission
Rolling element bearings have a long space mechanism heritage and are often the first choice in mechanism design.
These missions will involve advanced mechanical moving components, space mechanisms that will need wear protection and lubrication. In vacuum applications, such as equipment used in deep space, great care must be taken when choosing the bearing lubricant In these conditions, greases can vaporise to unacceptable levels. Vacuum and cleanroom environments present difficulties when specifying bearings due to the risk of contamination
