Guide rail length and hole spacing diagram
L3 = Standard rail lengths (mm)
L4, L5, L10 = Standard hole spacings (mm)
Calculating Non-Standard Rail Lengths
Individual rail lengths can be calculated with the following formula (up to a maximum rail length according to the above table):
L3 = (n-1) • L4 + L5 + L10
| L3 | = Rail length (mm) |
|---|---|
| L4, L5, L10 | = Individual hole spacing (mm) |
| L4 | = Standard hole spacing (mm) |
| n | = Number of attachment holes |
Position Tolerance of Attachment Holes and Rail Length Tolerance
Position tolerance measurement diagram
L3 = Rail length (mm)
L4 = Hole spacing (mm)
n = Number of attachment holes
t = Position tolerance (mm)
| L3 ≤ 300 mm | L3 > 300 mm | |
|---|---|---|
| Position tolerance t of attachment hole | 0.3 | 0.001 • Xn |
| Tolerance of rail length L3 | ±0.3 | ±0.001 • L3 |
