7001 Ball Bearings | McMaster-Carr

Install these bearings for use with combined radial and thrust loads. They are often used in spindle applications and can be combined with cylindrical roller bearings to better handle radial loads.

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.

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.
