Ball Bearings for Lead Screws and 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.

3/16" V-Groove Bearing

$9.98
Qty:
Small v-groove bearing.

These are specialized bearings that are used in many linear motion systems. The v-groove bearings generally ride on a rail or track. #10 Screws fit well with the inside diameter of this v-groove bearing. The inside diameter is .1875 inches (4.7625 mm), overall outside diameter .7675 inches (19.54 mm), inside of the "v" diameter is ,.6425 inches (16.31 mm) and overall width is .3095 inches (7.86 mm). If a small v-groove bearing is desired, this is a good choice.
