  • Linear Bearings 101 - How do Linear Bearings work

    2020-5-12 · Lets explain how Linear Bearings work Linear Bearings slide on a Linear Axis in a straight line. Because they are a bearing it allows you to move a significant amount of weight in a linear motion with great ease. The Linear Bearing takes all the weight without restricting the linear motion of the object, hence the name. Linear Bearing slide rails provide accurate, stable, and smooth linear ...
