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.
For technical drawings and 3-D models, click on a part number.
For Radial Loads
End supports for radial loads handle loads perpendicular to the lead screw.
