Angular-Contact Thrust Ball Bearings
Open
Single-row bearings handle thrust loads on one side. For applications with thrust loads on both sides, mount them in pairs.
Open bearings dissipate heat more efficiently than shielded and sealed bearings.

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 Combined Radial and Thrust Loads
End supports for combined radial and thrust loads handle radial loads (perpendicular to the lead screw) and thrust loads (parallel to the lead screw).
