Normally, the mounting base for the LM rail and the LM block has a datum plane on the side face of the shoulder of the base in order to allow easy installation and highly accurate positioning.
The corner of the mounting shoulder 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 rail or the LM block.
The values in the table each indicate the error allowance (S) in vertical level between two rails per 200 mm of the axis-to-axis distance, and are proportional to the axis-to-axis distance.

Note Since the LM block, LM rails, and balls are stainless steel, this model is highly resistant to corrosion and the environment.
*1 The maximum length under "Length" indicates the standard maximum length of an LM rail.
*2 Static permissible moment:1 block: static permissible moment value with 1 LM block
Double blocks: static permissible moment value with 2 blocks closely contacting with each other
● The following table shows a reference bolt-tightening torque for mounting the LM block of model SRS 5M/7M.
We have capacitity to provide above listed goods moreover we have rich export experiences for overseas market.
If any more interest please let me know, then we can talk more details, thank y
