Roller Screw Advantages
A roller screw is a mechanism for converting rotary torque into linear motion, in a similar manner as acme screws or balls screws. However, unlike acme or ball screws, roller screws are capable of carrying heavy loads for thousands of hours in the most arduous conditions. This makes roller screws the ideal choice for demanding, continuous-duty environments.
