This flatness depends on length thickness model and so on This deformation can be restored to original accuracy by proper installation Therefore this value can use as reference only However it is possible to occurring permanent deformation without proper storing Do not store the rack vertically or hang on part of rack only It must store flat floor with entire rack length support to maintain natural flatness Mm INSTALLATION The mounting surface for both the rack and the linear guiding system must be parallel within the specifications shown in Figure 3 This parallelism requirement is best achieved by machining the mounting locations for both the guiding system and rack in the same machining operation IGB recommends orienting the rack teeth downward or to the side so it minimizes the possibility of debris collecting on the teeth and causing meshing interference The model number displaying surface and arbitrary cut surface cannot be used as reference surface And any rack ends that have been cut must be located at the end of the run the pinion must not cross cut rack ends 1 Ensure that the mounting surface and rack are completely clean free of burrs or anything SEJINIGB gear box com 5 ABO 7 StOlaHOF St 2 A Abi Of Zo 142 Zo Col A AOR 2 PAT OS 254403 870M4 40 MAS Ho AHE Byres sy SO AZZA 0 03 mm SILO LEAS SOIC ES AHO HEHREN Ob 3 AM AS HAS AAP OM E AIA 3 AZS 0 So zae WSS
