Structure and Function of Push-Pull Cables

A push-pull cable consists of a stable inner cable or rod that is guided in a flexible but axially fixed cable sheath. Unlike a simple Bowden cable, the inner element in push-pull cables is specially stabilized to transmit not only pulling but also pushing forces.

Components of a push-pull cable:

  • Inner cable/Rod: Transmits both pulling and pushing forces, reinforced construction for pressure stability
  • Cable sheath: Guides the inner element and provides stability, e.g. with special spiral hoses
  • End pieces/Connections: Connection elements to the components to be moved, individually adaptable
  • Special guide elements: Guarantee precise guidance of the inner element even under pressure load

The careful coordination of all components guarantees optimal function even with complex routing paths. The correct dimensioning of the push-pull cable depends on the force to be transmitted, the routing path, and the environmental conditions.

Push-Pull Cables vs. Bowden Cables - The Right Choice for Your Application

Push-Pull Cables

  • Force transmission in both directions - both pull and push
  • Ideal for precise positioning and controlled bidirectional movements
  • Specially reinforced inner core for pressure stability
  • Higher precision through defined movements in both directions
  • Fewer components in the overall system due to bidirectional function
  • Easier integration into complex systems

Recommended for: Applications requiring precise bidirectional movements, such as positioning systems, locks, controls and adjustment mechanisms.

Bowden Cables

  • Force transmission only in pulling direction - no pressure transmission
  • Simpler construction and often more cost-effective
  • More flexible routing for complex paths
  • Lower weight due to simpler construction
  • Smaller minimum bending radii possible
  • Ideal for simple actuations and longer transmission paths

Recommended for: Applications requiring only pulling forces, such as release mechanisms, unlocking, simple switching operations and applications with limited installation space.

Frequently Asked Questions about Push-Pull Cables

What is the difference between a push-pull cable and a Bowden cable?
The fundamental difference lies in force transmission: A push-pull cable can transmit forces in both directions - both when pulling (tensile forces) and when pushing (compression forces). A Bowden cable, on the other hand, can only transmit tensile forces. Push-pull cables have a special construction with reinforced inner core that also transmits compression forces without buckling. This makes them ideal for applications requiring precise bidirectional movement, while Bowden cables are often sufficient for simpler, unidirectional applications.
What maximum forces can push-pull cables transmit?
The transmittable forces depend on the type and dimension of the push-pull cable. Our OPALTECH 7 series can transmit tensile forces up to 600 N and compression forces up to 280 N. The more robust OPALTECH 11 series enables tensile forces up to 1300 N and compression forces up to 650 N. As a general rule, the transmittable compression forces are always lower than the tensile forces, as there is a risk of buckling under compression stress. For specific requirements, we are happy to advise you on optimal dimensioning for your application.
What distinguishes push-pull cables from conventional Bowden cables?
The main difference lies in bidirectional force transmission. While Bowden cables can only transmit pulling forces, push-pull cables are capable of transmitting both pulling and pushing forces.
In which areas are push-pull cables mainly used?
Push-pull cables are mainly used in industry and special applications. In the industrial sector, they are used for machine controls, valve actuations, door opening mechanisms.
What advantages does OPALTECH technology offer for push-pull cables?
Our OPALTECH technology offers numerous decisive advantages for push-pull cables: Up to 10x longer service life, up to 3x lower operating forces, constant performance throughout the entire service life.
How is the OPALTECH 7.4 with 90-degree fixation constructed?
The OPALTECH 7.4 with 90-degree fixation features a specially developed T-handle at one end of the push-pull cable. This T-handle can be precisely rotated 90 degrees.
Can push-pull cables be used in extreme environments?
Yes, our push-pull cables are available for various extreme environmental conditions. By default, our OPALTECH cables are designed for temperatures from -40°C to +80°C.
What is the lifespan of push-pull cables?
The lifespan of push-pull cables depends on various factors: operating frequency, load level, routing and bending radii, environmental conditions, and technology used.
What maintenance do push-pull cables require?
Maintenance requirements depend heavily on the technology used. Conventional push-pull cables require regular lubrication and periodic inspection.
How do I choose the right push-pull cable for my application?
When selecting the right push-pull cable, the following factors should be considered: forces to be transmitted, stroke, installation path and geometry, environmental conditions.
What maximum length can push-pull cables have?
The maximum practical length is limited by pressure stability and friction losses. For our standard products we recommend: OPALTECH 7-series up to 2 meters, OPALTECH 11-series up to 3 meters.
How do push-pull cables behave with temperature fluctuations?
Temperature fluctuations can affect function through thermal expansion, changed material properties, and lubrication effects. Our standard push-pull cables are designed for -40°C to +80°C.
Can push-pull cables be subsequently adapted or shortened?
Subsequent shortening by the user is not recommended due to complex construction, special end connections, and endangering pressure stability.
What materials are used for push-pull cables?
Materials vary depending on the design. Standard version: High-strength steel wire for inner core, metallic spiral sheath made of galvanized steel.
How are push-pull cables properly installed?
Correct installation requires: checking suitability for the application, planning the route with minimum bending radii, straight-line laying where possible.
How exactly does force transmission work in a push-pull cable?
Force transmission is based on a sophisticated mechanical principle. Pulling forces are transmitted directly through the inner cable. Pushing forces require special construction.
What alternatives exist to push-pull cables and when are they preferable?
Alternatives include hydraulic/pneumatic systems (for higher forces), electric drives (for precision and automation), simple Bowden cables.
What common errors and problems can occur with push-pull cables?
Common problems include: increased operating forces (due to tight bending radii or contamination), buckling under pressure load.
