What does "guide surface" that appears often when choosing a product refer to? Also, what kind of calculation is used to deduce the resistance of the guide surface?
Guide surface refers to the LM Guides or Ball Splines in our product group. That is, it is a mechanism for supporting the weight of conveyed objects and guiding in a straight line. The resistance of the guide surface refers to the sliding resistance of guide surfaces such as LM Guides. Assuming that you use the LM Guide as the equipment you are considering, use the seal resistance values for each model listed in the general catalog.
