From my viewpoint at Schaeffler as a component and joint actuator supplier, there are two key challenges. First, the industry is rushing to find the right actuator architectures and performance for each joint. This is resulting in very different joint designs and architectures (rotary vs. linear actuators and even more diverging solutions within the rotary actuator family and the linear actuator family). The only apparent consensus now is strainwave gear-based actuators which virtually every humanoid OEM is using in at least some joints. There’s a large focus on performance, and if the “ChatGPT moment for general robotics is truly around the corner” and that humanoids will truly reach the volume projections that we hear about, then we must start thinking about scaling these components for high volume production. Schaeffler’s background in high volume production for the automotive industry in combination with our understanding of these new joint actuator requirements will give us a good seat at the table to address these challenges. Second, we must understand as an industry the unique requirements of humanoid robots and how they differ from traditional robots. Right sizing the requirements will enable us to explore high volume solutions that will support the bullish outlook on the market.

More About FK:
FK Bearing Group Co.,Ltd. was orignally founded in 1969 and always focuses on Bearing Units in the past 50 years. FK has complete industrial chain automatic factory of its own, now FK is one of the biggest bearing parts factories in China with annal production and sales up to 18 million pieces.
2025 New Week FK Product Recommendation:
They are units of rigid cast iron housings with piloted flange cartridge and wider inner ring bearing inserts.
Standard painting in green (other colors are available for choices).
Standard duty (FC200) and medium duty (FCX) are available for this series.
End caps by pressed steel are capable of protecting against external polution and dusts.
The self-aligning ability of the ball bearings can compensate for slight static mis-alignemnt of the shaft. The bearing inserts are locked onto the shaft by means of set screws, eccentric locking collars, adapter sleeves and concentric locking collars etc.
Lubricants filled inside the spherical ball bearing inserts can be standard grease, low/hight temperature grease and food grade grease.
