FAQ:

Q: What are the advantages of a linear motion guide?

A: 12. 5.ADVANTAGES OF LINEAR MOTION GUIDEWAYS Following are the advantages of LM Guideways due to which their demand for high precision work is increasing: 1. High Positional Accuracy When a load is driven by a LM guideway, the frictional contact between load and bed desk is rolling contact.

Q: What are linear motion guides?

A: Guide to Linear Motion Systems. Linear motion bearings are bearings that are made to move in a particular direction, and they come in a wide array of different designs. Some linear slides are motorized, others are not. Examples of the former include roller and XY tables as well as machine and dovetail slides.

Q: What is a linear guide?

A: Linear Guide overview. Linear Guides are a block and rail system that helps support the motion of an application. How linear Guides Work. There are two parts to the Linear Guide System: the Linear Block and the Linear Rail.

Q: What is a linear slider?

A: Linear Slides. Linear slides are devices which are used to provide free precision motion along linear planes for many different types of automated machinery for the purposes of pushing, pulling or positioning. The name “linear slide,” or “linear motion slide,” comes from the action these mechanisms carry out, i.e. linear motion.
