Product Review
Stainless steel 304, uncoated wire rope, with 7x7 standard construction, is used in pulleys, and in aircraft and automotive controls. Stainless steel 304, also called 18-8, is corrosion-resistant, and withstands high temperatures for a wide range of operation. Stainless steel 304 is a versatile material, commonly used in a wide variety of applications, and in saline atmospheres. Vinyl, also called Polyvinyl Chloride (PVC), is corrosion-resistant, lightweight, and has high strength. It resists reactions with acids, gasolines, alcohol, and hydrocarbons. It is flexible, and is resistant to weather and ultra-violet (UV) rays. Vinyl coating is a hard, durable plastic that resists most chemicals, has excellent dimensional stability, and can be sterilized. It resists oil, has absorbs low levels of moisture, and is non-conductive. 7x7 strand core has seven strands of wire rope with seven wires in each strand, formed helically around a strand core. 7x7 strand core is stronger but less flexible than 6x19 and 6x36 class constructions.
Wire rope, also called wire cable, is an assembly of wire strands formed helically around a central core. It is used for pulling, lifting, rigging, hoisting, and motion-control applications most commonly found in the manufacturing, marine, oil, mining, fiber-optics, aircraft, automotive accessory, and construction industries. A combination of characteristics including material, finish, construction, diameter, length, and breaking strength combines to give each rope its performance ability. Wire rope materials are selected for properties such as strength, elasticity, conductivity, and chemical- and weather-resistance. For strength purposes, most wire rope is made of bright (uncoated or bare) wire. However, it is also produced in a variety of finishes, such as polypropylene (PE), vinyl (PVC), or nylon. These coatings can increase overall durability and strength, and allow for specific use. The breaking strength for wire rope is the strength at which new wire rope will fail under a stationary load. Breaking strength is not considered safe working load (SWL) limit.
