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.
Included with each bearing assembly are: aluminum angles bored (hole drilled) and tapped (threaded) for 5/16" bolts, four 5/16" bolts, four 5/16" nuts and four bearings with a 5/16" inside diameter. The unit is based on the length of the bearing truck (aluminum angle). Two sets come with each purchase.
Bearings - For Linear Slides
These package counts are based on the common machine requirements. Specification: 5/16" inner diameter, approximately 1/4" thick, and the outside diameter is approximately 7/8".
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.
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.
V-Groove Bearings 3/16 inch ID
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.
