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.
Bearings - For Linear Slides
These package counts are based on the common machine requirements. Specification:
5/16" inner diameter, approimately 1/4" thick, and the outside diameter is approximately
7/8".

24 pack Three Axes Set
30 pack (Three Axes and two for each leadscrew)
V-Groove Bearings
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.

Bearings - Position 1/4" Lead Screws
Use these bearings to stabilize your 1/4" lead screw next to the coupling. Two per
axis is usually needed to secure the entire lead screw.
6-pack
Bearings - Position 1/2" Lead Screws
Use these bearings to stabilize your 1/2" lead screw next to the coupling. Two per
axis is usually needed to secure the entire lead screw.
6-pack
Bearings - Position 3/8" Lead Screws
Use these bearings to stabilize your 3/8" lead screw next to the coupling. Two of
these bearings are typically used for each lead screw, one bearing at each end of
each lead screw.
6-pack
Bearings - Position 5/8" Lead Screws
Use these bearings to stabilize your 5/8" lead screw next to the coupling. Two of
these bearings are typically used for each lead screw, one bearing at each end of
each lead screw.
