The main differences between flange-type roller linear guides and flange-type ball linear guides lie in the type of rolling elements, contact method, load capacity, rigidity, and applicable scenarios.
Rolling Elements:
Ball Type: Uses steel balls as rolling elements, forming point-to-surface contact.
Roller Type: Uses cylindrical rollers as rolling elements, forming line-to-surface contact.
Load Capacity and Rigidity:
Roller type has a larger line contact area, resulting in higher load capacity and rigidity, making it more suitable for heavy-duty and high-rigidity applications.
Ball type has a relatively lower load capacity but lower frictional resistance, making it suitable for light-duty and high-speed applications.
Structural and Installation Features
Both are flange-type sliders, meaning the slider has mounting holes at the bottom for easy fixing. They have a compact structure and low height.
Roller linear guides are generally not splicable, while ball linear guides can be spliced to extend the stroke.
