This Tray Lifting Screw is designed for operation and execution mechanisms in service robots, adopting a reverse planetary roller structure to achieve efficient conversion of rotary motion into linear motion. Its core advantages include high load capacity (point load up to 850kg) and long service life (600,000 lift cycles), making it suitable for precision lifting in logistics, medical, and food service robots. The screw surface is specially hardened, and the nut uses wear-resistant materials, ensuring stable accuracy under frequent start-stop conditions.
Features
High Load Design: Multi-row roller engagement structure, load capacity up to 3,700N, supports uneven loads (point load 850kg).
Long Service Life: Surface hardening and wear-resistant nut material, ensuring 600,000 lift cycles.
Compact Integration: Nut integrated as motor rotor, reducing volume, adaptable to confined robot spaces.
Energy Efficient: Rolling friction transmission efficiency over 90%, 50% lower energy consumption than sliding screws.
