In linear and sliding motion mechanisms, a linear shaft rod plays a crucial role. Without a linear shaft, we wouldn’t complete a sliding mechanism with linear power transmission.

But, the manufacturing and choosing of the appropriate linear shaft can get tricky. Linear shafts can have different structures and be made of various materials, depending on the properties needed.

So, we’ve decided to put together this in-depth guide to a linear shaft to help you stay in the loop and make an informed decision.

The linear shaft in power transmission applications is a long, rod-shaped tool used for support in linear motion, especially sliding motion. With a linear shaft, the motion can be guided and fine-tuned.

The load and specific requirements determine the size and precision of the linear shaft. Linear shafts made with tight precision tolerances are more durable and resistant to wear and tear.

In linear power transmission mechanisms, the shaft works together with an actuator, support rail, bushings (ball bearings), etc. In linear power transmission, the actuator typically does all the sliding work, while the rail, bushings, and linear shafts provide support .

Linear shafts have to be mounted before they're used. There are two main ways of linear shaft mounting – continuous support and end-supported. Linear shafts with continuous support are typically used for heavier loads, while those supported at both ends are used for smaller weight loads.
