A linear bearing includes a carriage and rolling element. The linear bearing is mounted on either a square or round rail depending on the requirements of the application. The rolling element of the bearing, whether it be ball or roller slides
This linear ball bearing is sort of the opposite of the radial ball bearings you may be familiar with. Its intended to slide along an 8mm linear shaft, rather than rotate around it. These are very slim, and good for when you want to attach a motion carriage onto a railing without adding a lot of weight. These are very basic bearings, they’re meant for a stepper-motion controlled setup so they’re not ultra-smooth. They’re best used for DIY/hobby robotics projects!
