6×19 & 6×36 Classification Wire Rope

6×19 Classification 6×36 Classification
6 outer strands having between 19 & 26 wires per strand 6 outer strands having between 27 & 49 wires per strand

The 6 x 19 classification of wire ropes includes standard 6 strand, round strand ropes with 16 through 26 wires per strand. The 6 x 36 classification of wire ropes includes standard 6 strand, round strand ropes with 27 through 49 wires per strand. Although their operating characteristics vary, all have the same weight per foot and the same minimum breaking force, size for size.

While the 6 x 19 ropes give primary emphasis to abrasion resistance in varying degrees, the 6 x 36 ropes are important for their fatigue resistance. This fatigue resistance is made possible by the greater number of small wires per strand.

Although there are exceptions for special applications, the constructions in 6 x 36 classification are primarily designed to be the most efficient for each rope diameter. As the rope size increases, for instance, a large number of wires can be used to achieve required fatigue resistance, and still those wires will be large enough to offer adequate resistance to abrasion.**

6x19S (Seale) This is a good rope to withstand abrasion or crushing on the drum, but its fatigue resistance is decreased.
6x25FW (Filler Wire) To most wire rope users, 6×19 means 9×25 filler wire. It is a common rope in the 6×19 classification.
6x26WS (Warrington Seale) A standard 6x26WS design provides the best rope for a wide range of applications. In general, we recommend the use of 6x26WS in any application where a 6x25FW is used.
6x31WS (Warrington Seale) 6×23 classification wire ropes are known for their fatigue resistance without having wires that are too small.
6x36WS (Warrington Seale) The greater the number of wires in the 6×36 classification makes these ropes more susceptible to crushing.
6×49 Seale Warrington Seale Crushing of 6×36 classification wire rope can be minimized by specifying an Independent Wire Rope Core (IWRC) and by using well-designed sheaves, grooved drums and proper operating techniques.
