The CRBT lightweight rotary joint bearing, with a section height of 5.5mm and a width of 5mm, is an extremely compact and lightweight bearing. Suitable for small robotic arms and miniature surveillance cameras.
Bearing Feature
Compared to the previous thinnest cross-roller bearing (CRBS), its section height is only 69% of its predecessor. The width is also only 5mm, and the cross-sectional area is only 43% of previous products, achieving a significantly smaller size. Moreover, its weight is only 0.38 times that of the CRBS, achieving substantial weight reduction. (Compared to a bearing with a 50mm inner diameter)
Advantages
This bearing has no mounting holes, resulting in an extremely compact structure and extremely light weight.
Applications
Humanoid robots, rotary tables, precision machine tools, joint modules, and other applications requiring extremely high installation space, weight, and precision.
