Overview of GKA Energy Chains
The GKA energy chain system is designed for high stability and customizable dimensions, suitable for guiding cables in demanding industrial applications. It supports long stay lengths up to 1200 mm and allows bending radii tailored to customer specifications.
Specifications and Dimensions
- Bending radius: From 200 mm upwards, customizable.
- Inner height range: 118 mm to 468 mm.
- Inner width range: 100 mm to 1172 mm.
- Energy chain weight: 25 to 85 kg/m depending on size.
- Stay lengths: Available in 1 mm increments; usable interior width equals stay length minus 14 mm.
Load and Travel Characteristics
The maximum travel distance depends on chain arrangement and additional line weight. Typically, maximum travel is twice the chain length minus the arc length of the bending radius. Use of support rollers can increase travel distance.
Travel speed: Standard and stainless steel types are limited to 1 m/s. Higher speeds or dynamic loads require carburated materials.
Acceleration: Generally unlimited but constrained by tensile forces in very long chains with heavy line weights.
Operating Conditions
- Service temperature range: -20 °C to 600 °C for standard; -40 °C to 600 °C for stainless steel versions.
Material and Types
GKA chains are available with aluminum profiles, stainless steel rods (GKR type) for offshore applications, and plastic dividers (GKP type) optimized for heavy mechanical engineering. Each type offers trade-offs in weight, price, and space efficiency.
Design and Customization
The bending radius is freely selectable after consultation to minimize polygon effects. Chains are custom-made based on client drawings, with order lengths chosen as uneven multiples of the pitch.

Connectors and Components
Various connector types (A, B, C, D) are available to suit different installation needs. The main parts include links with slots or drilling, connector links and angles, screws, nuts, retaining rings, aluminum profiles, plastic dividers, rods, and roller stays.
Applications
- Steel plants typically use GKA 161.
- Water power plants use GKR 260 (stainless steel rods).
- Mechanical engineering often uses GKP with plastic dividers.
Best Practices and Recommendations
- Consultation is recommended to select optimal bending radius to reduce polygon effect.
- Order lengths should be uneven multiples of the pitch for proper chain function.
- Use carburated materials for speeds exceeding 1 m/s or high dynamic loads.
- Consider support rollers to extend maximum travel distance.
Catalog excerpts
max. travel with 2 support rollers The maximum travel distance is determined by the arrangement and the additional weight (line weight). At normal arrangement maximum travel is double the chain length minus the arc of the chain radius. Support rollers or similar constructive steps can increase this value. Travel speed The standard and the stainless steel type are limited at 1 m / s. Exceeding this and high dynamic loads caused by eg vibrations need the use of carburated material. 16 4 12 8 free carrying length Lf / (m) The acceleration in principle is not limited. However limits may exist if very long chains and line weights cause extreme tensile forces. Service temperature application range The operating temperature is -20 ° C up to 600 ° C ( stainless steel -40 ° C up to 600 ° C).
