Linear Motion

While most bearing applications involve supporting a load on a rotating shaft, some applications exist where the movement of a load is required in a linear (back and forth) direction.

Common applications requiring linear motion are:

  • Indexing - packaging, machining, welding
  • Sliding - painting, ergonomics, transporting parts

Linear motion requires the use of an actuator to cause the load to move. Common actuators are hydraulic or pneumatic cylinders, as well as ball or threaded screws.
