Robotics is advancing rapidly across humanoid and collaborative robot applications, increasing the importance of precision components inside robot joints. Bearings play a critical role in supporting load, motion accuracy, stiffness, and stable repetitive movement.

In this article, we will explore the role of bearings in robot joints, the key characteristics that distinguish robotics bearings from general-purpose bearings, and the major bearing types used in robotics applications.

Global robotics industry continues to expand as automation spreads across manufacturing and new applications emerge for collaborative and humanoid robots. According to the International Federation of Robotics (IFR), 542,076 industrial robots were installed worldwide in 2024, while the global operational stock reached approximately 4.66 million units. Asia accounted for 74% of new installations, with Europe and Americas representing other major manufacturing markets.

Collaborative robots are also becoming a more established part of industrial automation. IFR data shows that 64,542 collaborative robots were installed in 2024, representing 11.9% of total industrial robot installations. At the same time, humanoid robots are attracting growing attention as companies explore their potential in manufacturing, logistics, and other human-centered environments.
