Product - Ball Bearings for Lead Screws and Linear Motion

Ball Bearings for Lead Screws and Linear Motion

Bearings are used to stabilize lead screws and provide fluid linear motion. All dimensions shown relate to the inner diameter of the ball bearing. Typically two bearings are needed for each lead screws (axis). If a three axis machine is being built, six bearings will be needed. The ball bearing size will depend on the lead screw diameter. The lead screw diameter must match the inner diameter of the ball bearing. For linear motion, 5/16" ball bearings are used. Please read the conditions of purchase prior to purchasing any products offered by BuildYourCNC.com.

V-Groove Bearings - Currently in Backorder

These are specialized bearings that are used in many linear motion systems. The v-groove bearings generally ride on a rail or track. Curious as to the application? Look at the blackToe system.
