Q
Conguration of the Base Structure
15.4 Geometric and Position Accuracy of the Base Surfaces
15.4.1 Permissible Lateral Deviation E1 for MINIRAIL and MINISCALE PLUS
Calculating height deviation E1
E1 = Q ∙ Vvsp
E1 = height deviation E1.1 + E1.2 in mm
Q = guide rail spacing in mm
V
vsp = preload factor (see following table)

Calculation example for E
1
Example: Type MNN 12 in preload class V1
Spacing Q = 120 mm
Calculation: Type MNN 12 in preload class V1 results in a preload factor
V
vsp of 0.00015
0.00015 x 120 mm = 0.018 mm
Comment: The deviations of E1.1 and E1.2 (= E1) must not exceed 0.018 mm.
