軌道台を基準取付面にボルトで締め付けた状態で、スライドユニットを全ストローク走行させた時の、A 面に対する C 面及び B 面に対する D 面の平行度誤差の事を言います。
「Pair Tolerance of the Height"H"」
This is the maximum tolerance of the height"H" of plural slide units built-in on the same plane.
「Pair Tolerance of Width N(W4)」
This is the maximum tolerance of the width N(W4)between track rails and plural slide units mounted on a track rail.
・Size tolernce of Width N(W4)and pair tolerance apply only to the datum plane.
・When more than one LMB guides are used in parallel on the same plane, size tolerance of width N(W4)and pair tolerance apply only to an LMB guide on reference side. The track rails on reference side are marked with "P".
「Traveling Parallelism」
This is the parallel tolerance of the distance from reference side plane A to plane C and from reference side plane B to plane D , when a slide unit is run in specified strokes while the track rail is mouted with bolts to the mounting surface of datum plane.
