Ball Screws

Ball Screw
A ball screw is a mechanical linear motion device that converts rotational motion into linear motion with minimal friction. It consists of a screw (or lead screw) with a spiral groove and a ball nut containing ball bearings that roll between the screw and nut to transfer the rotational motion to linear motion. They are ideal for applications that require accurate linear motion and positioning.

Features and benefits:
  • High efficiency
  • High precision
  • High load capacity
  • Low friction
  • Low backflash

Q: What is backlash, and how do ball screws address it?

Backlash is the clearance between the screw and nut. Ball screws minimize backlash, contributing to enhanced positional accuracy in applications.

Q: How do ball screws work?

When rotational motion is applied to the screw shaft, the nut containing recirculating steel balls moves along the helical grooves, converting rotational motion into linear motion.

Q: How do ball screws compare to other linear motion mechanisms?

Ball screws are known for their high efficiency and precision compared to other linear motion mechanisms. They offer advantages in terms of reduced friction, backlash, and increased load capacity.
