Ready-Mount Bearing Housings

Mount bearings quickly by using these precision housings, which don’t require any machining. They support a shaft that’s parallel to their mounting surface and let you replace the bearings as needed. Made of aluminum, they’re lightweight, durable, and have good corrosion resistance.

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.
