Recommended rail lengths
| L = nB · T – 4 |
T = hole spacing (mm)
nB = number of holes
(up to Lmax):
Guide rail size 12, accuracy class P, recommended rail length 771 mm
(30 · T, number of holes nB = 31, T1 is identical at both ends of the guide rail)
Ordering data: R0445 202 31, 771 mm
Ordering example 2:
(up to Lmax with cover strip):
Guide rail size 12 with cover strip, accuracy class P,
recommended rail length 771 mm (30 · T, number of holes nB = 31,
T1 at one end of guide rail = 4.5 mm)
Ordering data: R0445 262 31, 771 mm, T1 = 4.5 mm
(At the other end of the guide rail T1 = 16.5 mm for production reasons.)
(composite rail over Lmax):
Guide rail size 12, accuracy class N, recommended rail length 1271 mm,
2 sections (50 · T, number of holes nB = 51, T1 is identical at both ends of
the composite guide rail)
Ordering data: R0445 204 32, 1271 mm
*2 = Number of sections
Ordering example 4:
(one-piece over Lmax):
Guide rail size 12, accuracy class P, recommended rail length 1771 mm
(70 · T, number of holes nB = 71, T1 is identical at both ends of the guide rail)
Ordering data: R0445 202 31, 1771 mm
If no T1 is specified by the customer, both ends of the guide rail will be identical.
The rail lengths were calculated using the formula for recommended rail lengths.
