These bearings can be used for any shaft or screw that measures 3/8". We used these to allow 3/8" lead screws to be rotated.
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.
