Drilling aid for pinning the Shaft
The length of the Timing Belt and Strip is calculated as follows:
1. Timing Belt: KLE 6 60x60: LTB = 2 x L
profile
+ 162 mm
KLE 8 80x80: LTB = 2 x L
profile
+ 246 mm
The formula already factors in an additional tooth as a safety factor
plus a tooth of Timing Belt R25 AT5 PAR: + 5 mm
plus a tooth of Timing Belt R34 AT10 PAR: + 10 mm
2. Strip:
L
Strip
= L
profile
- 2 mm
The Strip at the bottom of the profile reduces the frictional losses of the moving
Timing Belt.

We recommend the following dowel for pinning purposes:
KLE 6 60x60 Dowel Pin DIN 6325-4x14
KLE 8 80x80 Dowel Pin DIN 6325-6x18
For KLE units with Shaft lengths in excess of 3 m, Shafts D10 (KLE 6
60x60) / Shaft D14 (KLE 8 80x80) must be butt-joined. There must be no
more than one butt joint. The recommended minimum Shaft length is
L
Shaft min
= 300 mm
The butt joints thus created on the Shafts can be opposite each other, i.e. they
do not have to be offset to each other, since the rollers of the Carriage are
offset.
The ends of the Shafts must be clean and free of burrs and chamfered
edges.
Use the Drilling Jig (part of Assembly Set KLE-LR 0.0.612.72) to pin the
butt-jointed Shafts at the joints but not
at the ends of the profiles too.
The
recommended distance d from the fixing bore to the butt joint is:
KLE 6 60x60: d = 30 mm
KLE 8 80x80: d = 40 mm
KLE 6 60x60
KLE 8 80x80
