製品説明
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 2 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.
