About Non Rotating Wire Rope
Non Rotating/Rotation-resistant wire ropes are specially designed to re-sist spin or rotation while under load.
Due to their design, they have certain restrictions on their application and special handling requirements that are unnecessary with other constructions.
The rotation-resistant characteristics are attained by a design of two or more layers of strands having differing (right and left) directions of lay, as shown below.
Under load, one layer’s directional rotation is counteracted by the tendency of the other layer(s) to rotate in the opposite direction. To impart greater resistance to rotation, these ropes are
designed with a greater number of smaller diameter strands (when compared with the design of 6- strand constructions).
The combination of smaller diameter strands and differing rope lays makes for a very delicate balance which can easily be “unbalanced” at anytime.

Features
18x19 Non Rotating Wire Rope
These wire ropes are softer than 18x7 series wire ropes. They are linear contact wire ropes. They have below features:
Good resistance to rotation.
Superior bending fatigue life when compared with conventional multistrand ropes
Excellent resistance to crushing and abrasion resulting from the overall compactness and robustness of the rope and the Dyform strands
Reduced elongation results from increased steel content and the Dyform process.
