19x7 ROTATION RESISTANT WIRE ROPE

 

 

19x7
A 19x7 is made from 19 strands and is a category 2 rotation resistant rope. It is used where resistant properties are essential for rope performance. Its rotation resistant characteristic is achieved by laying six strands around a core strand in one direction, then laying 12 strands around the first operation in the opposite direction. Thus, when the rope is in tension, opposing rotational forces are created between the inner and outer layers.

While having similar rotation resistance to a Flex X-19, a 19x7 has a lower strength, will crush easier and is not as fatigue or wear resistant.
