Design Guideline
Standard Control Cables
The basic specifications for each of
the control series are defined on the
accompanying capabilities chart. This chart shows the basic operational characteristics
for each of the control series. Load carrying capability and bend radius are the
distinguishing operating characteristics between series.
The standard configurations described
on the following pages accommodate applications where input and/or output actions have
straight push-pull motion. Where an arc articulation is required, a
ball joint connector is recommended
(See Accessories for selection). Rigid
mounting of control cable end fittings is achieved with jam nuts and washers on
the threaded portions of the main sleeves.
When required by a specific application,
a number of options are available for
sealing the control from the environment. These include seal nuts which are mounted on the
main sleeve and seal against the end rod and bellows assemblies as described on the "Ball
Joint Connectors, Seal Nut, Bellows
Assembly" page found in the
"Accessories" section of Mechanical
Controls. |

(a) Lengths
greater than 50 ft. will be supplied in (2) or more equal lengths with appropriate
couplings.
(b) Control cables are best shipped and stored in the figure "8"
configuration received from the factory. This minimizes the
possibility of damage. • Normal duty assumes a minimum product life of
100,000 cycles.
• Rated compression loads are limited to 4 inch
maximum stroke.
• Duty cycles greater than 100,000 cycles can be
achieved with increased bend radii on the control. |
