triflex® R TRCF.85

Here you can configure your E-ChainSystem® individually. All entries and changes are taking over to the part list which is situated at the end of the page.

System triflex® R Series TRCF.85

1. TRCF - closed design with snap lock
2. High tensile force absorption due to ball-and-socket joint{
3. For multi-axis movements - twist of approx. ± 10° per chain link in the longitudinal axis
4. Easy opening for large, rigid hoses and/or many cables
5. Easy to add and remove - one injection-moulded component
6. Abrasion-resistant and dirt-repellent
7. 3-chamber system for interior separation
8. Small bend radii, small pitch
9. Easy integration with, and accessories for your machine

When to use Series TRCF.85:

If a secure energy supply is required for multi-axis movements
If high torsion resistance is required
If the system must be easy to lengthen and shorten
If a small bend radius is required
If high tensile strength absorption is important
If a smooth and robust outer contour is required to avoid snagging

When not to use Series TRCF.85:

For circular movements with high loads
twisterchain® system
If an easy-to-fill variant is required
triflex® R TRE system
When a cost-effective, less sophisticated 3D solution is required
, triflex® R TRL system

To ensure a better, gentler movement of the cables being guided, compensation must be provided for extreme torsion and reverse bending, especially for sensitive cables with a large bend radius (e.g fibre optic cables)
2 versions (with or without strain relief)
Pivoted mounting with maintenance-free igubal® spherical bearings
Minimising the critical reverse bend
Movements are gentler
