Through the roller type line contact method, the service life of the guide rail is extended. Ultra-high rigidity can greatly improve accuracy and load
YGG series linear guideways are classified into non-interchangeable and interchangeable typesThe sizes of these two types are the same as one another. The main difference is that the inter-changeable type of blocks and rails can be freely exchanged and they can maintain P-class accu-racy. Because of strict dimensional control, the interchangeable type linear quideways are a wisechoice for customers when rails do not need to be matched for an axis, The model number of theYGG series identifies the size, type, accuracy class, preload class, etc.
Non-inerchangeable Type code:
