High-Speed Angular-Contact Thrust Ball Bearings
Open
An ABEC-7 rating means these bearings are made to some of the tightest tolerances, so they operate at the highest speeds.
Open bearings dissipate heat more efficiently than sealed bearings.

Metric 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. End supports handle radial loads (perpendicular to the lead screw) and thrust loads (parallel to the lead screw). Note: The end of your ball or lead screw must be machined before installing it into an end support.
