Shoulder height of the mounting surface and the corner radius Normally, the mounting surface for the LM block and the LM rail has a datum plane on the side face in order to allow easy installation and highly accurate The corner of the mounting surface must be machined to have a recess, or machined to be smaller than the corner radius "r," to prevent interference with the chamfer of the LM block or the LM rail. Qlblerance in parallelism between 2 rails The following table shows the tolerance in parallelism (P) between 2 rails. Qlblerance in vertical level between 2 rails The following table...

Standard length and maximum length of the LM rail The following table shows the standard length and the maximum length of the LM rail of the Oil-Free LM Guide for special environments. If the overall rail length exceeds the maximum length, contact THK. For dimension G if you require a special length, we recommend using the dimensions in the table. If dimension G is longer, the respective part tends to become unstable after installation, which may negatively affect the accuracy. Standard length and maximum length of the LM rail Note 1 : If you desire a rail length larger than the maximum...

EFÜ=¡ln£ Oil-Free LM Guide for Special Environments • Pulling out the LM block from the LM rail will cause balls to fall, or damage the Dry Lubrication S-Compound Film when reattaching the LM block. If it is necessary to remove the LM block from the LM rail, contact THK. • Do not disassemble the parts. Doing so may cause entrance of dust or a functional loss. • Tilting the LM block or the LM rail may cause it to fall by its own weight. • Do not drop or hit the LM Guide. Doing so may cause injury. It may also cause failure or breakage. Applying an impact to the product may cause a functional...
