  • Linear Bearing Manufacturers | Linear Bearing Suppliers

    Slide bearings or linear plain bearings are the most basic type of linear bearing. Their name stems from the fact that they operate by two surfaces sliding against each other. They perform linear movement and weight bearing using low-friction metals such as graphite and Teflon, as opposed to metal backing plates.
