Ball nuts and steel flanges are available for each screw size and lead.

Ball nut lead screw. Several ball screws are available in either right hand or left hand threads. Duff norton offers ball nuts and also bronze or plastic acme nuts. The nut travels only when the screw turns so your system won t unexpectedly move when the lead screw is at rest. It consists of a ball screw and a ball nut packaged as an assembly with recirculating ball bearings.

They feature a number of variables including type of nut screw diameter screw pitch material etc. Starts and lead revisited back to lead for a minute. Lead screws use deeper helical threads and a mating nut which is usually made of a polymer composite or bronze. Verify the screw selection and nut configuration.

A set of ball bearings reduces friction and secures the end of a ball or lead screw. Choose the ball nut capacity that meets your application requirements.

This is an important specification not only for linear travel and speed but also because a ball screw s lead determines how many balls are in the load zone in contact with the screw shaft and ball nut and therefore has a direct impact on load capacity. Acme lead screws and nuts found in hand powered clamps vises grates doors and work tables lead screws and nuts have broad square threads that are well suited for quick assembly high clamping forces and lifting and lowering. The screw and nut on a ball screw have matching helical grooves that allow ball bearings to re circulate in those races and are typically semi circular in shape to accept the spherical ball bearing. They convert input torque from rotary motors into linear motion.

Verify the screw s capacity and speed. Ball screws and nuts internal ball bearings provide smooth low friction travel in applications that require high speeds accurate positioning and repeatable movement. The ball screw drive is an assembly that converts rotary motion to linear motion or vice versa.
