ACME Lead Screws

ACME Lead Screws

Sometimes called power screws, turn these ACME screws to create linear motion and transmit power to lift or move a load. The ACME thread pattern sheds dirt and debris and is well suited for use in dirty environments. Self-locking ACME screws do not require a braking mechanism to hold the screw in place when stopped, making them ideal for applications where backlash is a concern. They are self-lubricating and produce less vibration and noise than ball screws. Recommended for applications with moderate speeds and heavy loads, such as screw jacks, presses, linear actuators, and vises.
