End Supports for Lead Screws and Ball Screws
A set of ball bearings reduces friction and secures the end of a ball or lead screw. Note: The end of your ball or lead screw must be machined before installing it into an end support.

End supports for radial loads handle loads perpendicular to the lead screw.

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 heavy objects. To ensure compatibility, please select components that have the same thread direction, thread size, and number of thread starts.
Cast iron components have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
For technical drawings and 3-D models, click on a part number.
Handles fasten and position lead screw components. Handles are easy to grip and tighten by hand for quick assembly and disassembly.
