Keep it light. Keep it direct.
A lightweight, fixed route for collaborative robots and small six-axis arms where the motion is predictable and the bundle does not need rotation or long-stroke compensation.
A lightweight, fixed route for collaborative robots and small six-axis arms where the motion is predictable and the bundle does not need rotation or long-stroke compensation.
The series number is a routing decision, not a product grade. Start with the motion and environment, then let the model, bundle and service access narrow the geometry.
Start here when — and stop when.
Good starting point
- Handling, palletising, machine tending, laser vision and routine grinding with a controlled path.
- The route does not need significant torsion or long-stroke compensation.
- Weight, installation envelope and cost are important constraints.
- The tool or cable bundle needs a clear, serviceable connection at both ends.
Not the first answer
- Continuous wrist rotation is the main problem; review Series 2 instead.
- The route changes length materially; review Series 3 or Series 5.
- Spatter, slag or impact reaches the outer layer; review Series 4.
- The robot flange and J3/J4 fixing points have not been checked by exact model.

Three things the drawing has to answer.
Keep the moving mass low.
Use the shortest supported route that preserves the cable bend radius. Avoid adding mechanism without a motion reason.
Design the fixing points.
Check the robot flange, J3/J4 points and bundle direction together. A conduit diameter alone is not an installation drawing.
Leave a maintenance path.
Keep cable separation, connector access and local replacement space visible from the start.
Five checks before a drawing is released.
Step 01
List the robot model, payload and reach.
Step 02
Count the cables and hoses; measure the assembled outer diameter and minimum bend radius.
Step 03
Check the J3/J4 path and fixing points through the full motion envelope.
Step 04
Select the standard diameter from bundle fill and bend radius.
Step 05
Release the interface drawing, BOM and installation note; trial-fit where needed.
When this series is not enough.
Series 1 is deliberately simple. If the duty needs continuous rotation, large stroke or spatter protection, adding more fixed points will not solve the motion problem. Move to the architecture that matches it.
Ask before you commit.
Can Series 1 be used on collaborative robots?
Yes, as a starting point for a controlled path. The exact model, flange, J3/J4 points and cable route still need to be checked; similar-looking collaborative arms can have different fixings.
Series 1 or Series 3?
Use Series 1 for a short, predictable, fixed route. Use Series 3 when the route must absorb a material length change and rebound.
Can I choose the diameter from cable cross-section?
No. Use the assembled cable and hose outer diameter, bundle fill and minimum bend radius. Cross-section alone does not describe the route.
What is needed for a non-standard robot?
A 3D model, flange dimensions, fixing-point envelope and the cable/hose list. The bracket and route are then checked as a project-specific assembly.
One model. One envelope. One useful answer.
If the robot code is known, we can skip the generic kit conversation and start with the interface.
