blog about Fortatech Launches Bidirectional Pushpull Cables for Precision Motion

In the world of precision mechanics, where every micron of movement matters, traditional Bowden cables may no longer meet the demands of cutting-edge applications. Fortatech AG's OPALTECH push-pull cables represent a breakthrough in bidirectional force control, offering unprecedented flexibility and reliability for mission-critical systems.

Unlike conventional Bowden cables, Fortatech's push-pull systems transmit force in both directions with equal precision. This dual-capability makes them ideal for applications requiring exact positioning through flexible pathways. The OPALTECH technology ensures maximum performance throughout the product lifecycle with minimal operational force.

Developed in collaboration with materials research institutes, OPALTECH technology represents a quantum leap in friction optimization and material engineering. This innovation not only enhances efficiency but significantly extends service life while reducing maintenance requirements.

At the core of each push-pull cable lies a stabilized inner rod or wire, precisely guided within an axially fixed yet flexible outer sheath. This sophisticated construction enables reliable transmission of both tensile and compressive forces - a capability absent in simple Bowden cable systems.

From industrial robotics to medical devices and automotive engineering, OPALTECH cables deliver precision control wherever bidirectional force transmission is required. Decades of engineering expertise allow Fortatech to provide optimized solutions for virtually any application scenario.

The OPALTECH series offers two primary product families:

• OPALTECH 7 Series (7mm diameter) for precision applications
• OPALTECH 11 Series (11mm diameter) for heavy-duty requirements

The OPALTECH 7 series transmits up to 600N tensile force and 280N compressive force, while the robust 11 series handles 1300N tension and 650N compression. Compressive capacity remains lower than tensile due to potential buckling risks under pressure loading.

Standard OPALTECH cables operate reliably from -40°C to +80°C, with specialized versions available for extreme temperatures or corrosive environments. Proper installation with adequate bend radii ensures optimal performance throughout the product lifecycle.

While traditional push-pull systems require regular lubrication, OPALTECH technology significantly reduces maintenance needs. Service life depends on operational frequency, load conditions, routing geometry, and environmental factors.

Key selection criteria include required force transmission, stroke length, installation path geometry, and environmental conditions. Maximum recommended lengths are 2 meters for the 7 series and 3 meters for the 11 series, with custom solutions available for specialized requirements.
