Lead Screws Roll Over Ball Screws
SERVO-DRIVE's lead screws have exceptionally shorter lead times, offer higher performance and are more cost effective.
Servo-Drive offers 5 different styles of nuts from free wheeling non antibacklash nuts to a user adjustable anti-backlash nut. All of these nut styles are available on screws ranging from 3.2mm to 15.9mm in diameter with leads as fine as 0.3mm up to fast leads as high as 31.75mm. Contact Servo-Drive today for your custom linear motion solution.
Our standard offering is a proprietary self-lubricating polyacetal thermoplastic that offers the following traits:
