twisterchain guide troughs
The bottom stanchion (in red) is required only if the support for the upper run (from a 180° angle of rotation) cannot be mounted on the machine.
twisterchain guide troughs
The twisterchain guide trough offers several advantages:
- Chain guidance
- Minimized wear on the chain
- Optimal running smoothness
- Rotational angle possible up to 400°
The modular design of the guide trough makes it possible to connect different chains, directions of movement, and bend radii using the same trough parts. If the chain radius changes, the trough can simply be adapted without purchasing a completely new trough. You can select the right guide trough system for your application from the table below. The part numbers given here are for the complete trough system. Please state the twisterchain series when ordering.
Order example
R - Bend radius (please add appropriate value)
Bi - Inner width (please add appropriate value)
Outer radius
Trough angle (Standard 180°, 135°, 90°, 45°)
Trough version (-5- with and -4- without bottom support)

Support for the upper run (from a 180° angle of rotation)
The guide trough must be mounted at the fixed end of the twisterchain, as shown by the drilling template. The following bolted connections are permitted:
- Through-hole: 4 • Ø 0.26" - 0.28" (6.6 - 7 mm)
- Mounting only with bolts: 4 • M6 bolts
- Markings:
A = Lower edge moving end
B = Lower edge fixed end
C = Upper run support
D = Required clearance for twisterchain
E = Rotary axis
F = Fixed end
G = Upper run support
H = Required clearance for twisterchain
I = Upper run support
J = Rotary axis
K = Fixed end
