Tsubaki's Power-Lock are also used in handling robots used in clean rooms for transferring materials.
Handling robots have many joints, which are driven by belt pulleys.
Since the drive is a servo motor or stepping motor, precision is required, so key fastening with backlash is not possible.
If the capacity is small, D-cuts and nuts are generally used for fastening, but as the capacity increases, Power-Lock are mainly used.

Since it is used in a clean room, an environmentally resistant series of Power-Lock is also used.
The stainless steel series is used for semiconductor wafer transport robots, which are often used in highly clean environments.
Electroless nickel plating is mainly used for FPD-related transport, which has a relatively low cleanliness level (class 1000 or higher).
