An aluminium-made light fulcrum for securing an LM shaft. Since the LM shaft mounting section has a slit, the fulcrum is capable of firmly securing an LM shaft using bolts.

Round shafting systems act as key structural elements in automation. They consist of one or more round rails fitted with bushings that enable the load to move along the shaft. Bushings typically move axially as well as rotationally. They are not intended to transfer torque.

Bushings are available with a variety of characteristics, including sliding contacts and ball-based contacts. Although they are commonly cylindrical, they can also be arc shaped to enable the bushing to pass over areas of intersection with other shafts. Preload can be adjusted to tune sliding or rolling friction.

Round shafting systems perform many of the same functions as linear guides but in less-demanding systems. They are designed to handle lighter loads, but can provide a cost-effective solution for the right applications.
