Linear guides use balls and rollers for transmission. Their advantages are high precision, large load and torque.
Many linear guides are made of 55# steel and chrome bearing steel, such as GCr15. Carburized bearing steel, such as G20CrMo, can also be considered.
Linear guides are easy to install and interchange. They use precision processing technology, high straightness of the rails, small error of the mounting screw holes in the rails, and easy installation. Linear guides are interchangeable. The sliders or rails can be replaced separately, or even the linear guides, to make the machine reach high precision again. Greatly reduce the driving power.
High working precision linear guide movement has very small friction. Only a small amount of power is needed to make the machine move, which significantly reduces the power loss of the machine. The heat generated by friction is very small. It is suitable for high-speed, frequent starting and reversing moving parts.
