Linear guides are mainly used in automated machinery, such as machine tools, bending machines, and laser welding machines imported from Germany. Linear guides and linear shafts are generally used together. They have the characteristics of high-speed movement, low coefficient of friction, and high sensitivity, thus meeting the working requirements of moving parts. For example, they can be installed and used in machine tool tool holders and slides.
How do you choose a linear guide?
The so-called usage conditions mainly refer to factors such as the type of equipment used, accuracy requirements, rigidity requirements, load type, stroke, operating speed, usage frequency, and operating environment. The appropriate product series should be selected based on these conditions. Each linear guide manufacturer has appropriately categorized its products into series.
Under the same conditions and rated load, the following two points should be noted:
The so-called rated life refers to the operating distance of a batch of identical products, where 90% of them have not experienced surface peeling.
Linear guides are generally classified into five precision grades: standard, high, precision, ultra-precision, and ultra-high precision.
The term "travel parallelism" refers to the parallelism error between the guide rail and the slider's reference surface when the linear guide rail is fixed on the reference base plane and the slider travels along its stroke.
