All the size could be maintained at a stable tolerance range, so the interchange type linear guide can keep the same smoothness, preloading and precision when the block arbitrarily assemble on the same type of rail .It is very easy to assemble and repair.
The selection of linear guides must be based on service conditions, load capacity and life expectancy. The so-called use conditions mainly refer to the application of what equipment, accuracy requirements, rigidity requirements, load mode, travel, operation speed, frequency, use environment and other factors. Choose the appropriate product series according to the conditions. Each manufacturer of linear guides has made a suitable series division for its products. Taiwan HIWIN's linear guides are mainly divided into HG series, LG series, AG series, MG series and so on.
