Product Description
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.
Application
Medical - dental chairs, instrument adjustments, scan heads, surgical tables, and more;Automotive - anywhere where linear power for sliding is needed, such as car seat mechanisms and similar;Aerospace - used in many mechanisms such as the plane/passenger seat adjustment;Packaging/printing - many printing and food packaging machines use linear motion shafts in their production;Machine tool.
