With over 80 years of combined experience in the small-diameter mechanical cable assembly business, NCA provides our customers with cable and wire rope assemblies made to their unique specification.
What is OEM?
Original Equipment Manufacturer (OEM) is a company that makes a part or subsystem that is used in another company's end product.
Do you sell electrical cable and wire rope?
No, we only sell mechanical cable and wire rope assemblies.
Do you purchase your wire rope and end fittings from USA producers?
We source our materials from all over the world. However, the vast majority of the wire rope and end fittings we purchase are produced right here in the United States. If you require 100% of your assembly or lanyard to be fabricated to be from US companies, we are happy to make sure that happens.
Am I able to get a sample of my cable or wire rope assembly?
Absolutely. Please contact our sale team to discuss your needs.
Are the wire rope or cable assemblies tested?
Pull testing and proof loading are the best ways of testing the strength of both the materials and the wire rope assembly. NCA will test your assembly to meet your specific requirements.
Can you provide Certifications for your assemblies?
Yes. We are happy to supply Certifications on our cable and wire rope assemblies and lanyards when requested.
What does DFARS stand for?
What does DFARS stand for? DFARS stands for Defense Federal Acquisition Regulations. DFARS is used by the Department of Defense. DFARS 252.225-7014 Preference for Domestic Specialty Metals was issued under the office of the Secretary of Defense for Acquisition and Logistics. The basic requirements of DFARS include that in order for a US company to use Specialty Metals, the metals must be melted in the United States or a qualifying country. When DFARS is included as part of a purchase order it invokes the Berry Amendment, also know as the Preference for Domestic Specialty Metals. It requires that the material used in the manufacture of the fasteners in the United States be melted in the United States or a qualifying country.
What are Qualifying Countries?
The qualifying countries listed under DFARS are Australia, Belgium, Canada, Denmark, Egypt, Germany, France, Greece, Israel, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, United Kingdom and Northern Ireland.
What are Specialty Metals according to DFARS?
Steel with a maximum alloy content exceeding one or more of the following limits. Manganese, 1.65%, Silicon, 0.60%, or Copper, 0.60%, or containing more than 0.25% of any of the following elements. Aluminum, Chromium, Cobalt, Columbium, Molybdenum, Nickel, Titanium, Tungsten, or Vanadium. Metal alloys consisting of Nickel, Iron-Nickel, and Cobalt base alloys containing a total of other alloying metals except Iron in excess of ten percent, or Titanium and titanium alloys or zirconium and zirconium base alloys.
Why is it called Aircraft Cable?
"Aircraft Cable" was originally developed to meet the needs of the early aircraft industry. The cable required for properly operate flight controls of aircraft needed to be flexible, high strength and small diameter. Over time, the uses of these cable became far wider and more diverse across numerous industries, yet the "aircraft cable" name stuck.
What is the difference between a wire rope assembly and a lanyard?
There really is not much difference between a wire rope assembly and a lanyard. A lanyard is an assembly. An assembly is the combination or a piece of wire or cable together with an end fitting. Wire rope or cable assemblies are used to connect two parts of a project. While assemblies will not be most advanced construction in a piece of equipment or machinery, they are often vital to its overall function and performance. Using NCA ensures you get the best quality assembly as the best price resulting in total satisfaction from your customers.
What questions should I ask when designing an assembly or lanyard?
First, consider the strength and flexibility of the cable you want to use. You will also need to determine the proper length of the cable. This will need to determine where to best measure your assembly, from end to end, from the center of the loop or eye? Your end use and the type of end fittings you elect will help you decide the best point of measurement. Next you need to decide whether or not your cable needs to be coated or if base cable is more appropriate. Some of the reasons to opt for coated cable include, for aesthesis, to reduce friction or to protect from the environmental conditions. Once your cable choices have been decided upon, you need to select loop size and/or end fittings you will need. In most cases this will be dictated by the ultimate use of the assembly. End fittings include sleeves, Stamped Eyes, Stop Sleeves, Strap Eyes and Strap Forks, Thimbles, Plain Balls or Ball Shanks, Retaining Tabs, Threaded studs or Winch hooks to name just some options. Let our sales team help you find for the best options to meet your unique need.
What does Mil Spec mean?
Mil Spec stands for Military Specification. It is what the military or Department of Defense use to "describes the essential technical requirements for purchased material that is military unique". This does not always equate to quality. These standards are used more for standardization purposes within the bidding and furnishing of military equipment and supplies rather than for quality. Many commercial standards are at equal if not higher quality.
Does Mil Spec mean better?
Military Specification does not always equate to higher quality. These standards are used more for standardization purposes within the bidding and furnishing of military equipment and supplies rather than for quality. Many commercial standards are at equal if not higher quality.
What does 7x7 or 7x19 in terms of cable mean?
7x7 or 7x19 describes the construction type of the cable or wire rope. The 7x7 or 7x19 are the most common used in cable or wire rope assemblies. Cable is constructed by wrapping a wire or strand helically or spirally around a core. In 7x7 cables, there are 7 strands (6 strands wrapped around a core strand) and each strand consists of 7 individual wires (again 6 wrapped around one core). The 7x19 has 7 strands and each strand consist of 19 wires (one core wrapped by 6 which are wrapped by 12). Both of these are considered Aircraft Grade Cable. While both are flexible, the 7x19 is more flexible.
What is the difference between dry (non-lubricate) and lubricated cable?
Some cable and wire rope are manufactured using a lubrication to lower the friction in cables and wire rope used over pulleys and to improve weatherproofing. This is done to increase the useful life of the cable. The lubrication used is generally low viscosity oil. Military Spec cable will be lubricated cable. Commercial grade cable is generally non-lubricated or “dry” cable.
Why would I choose lubricated cable?
Lubricated cable is best utilized when your cable assembly will be used in manner which causes friction (such as over a pulley) or if it will be exposed to extreme environments.
Is there a price difference between lubricated and non-lubricated cable?
Yes, the non-lubricated will be less expensive. Please contact our sales team to discuss the best option for your cable assembly needs.
What are the option for cable and wire rope coating?
While there are numerous options for coating of cable and wire rope, the most common are bare (not coated), Nylon and PVC (Polyvinyl chloride). Some of the reasons for selecting coating are to protect the cable from the environment or unwanted materials, to help reduce friction and abrasion, or simply for aesthetic reasons.
What is the difference between Nylon and PVC coating?
While there are numerous options for coating of cable and wire rope, the most common are bare (not coated), Nylon and PVC (Polyvinyl chloride). Some of the reasons for selecting coating are to protect the cable from the environment or unwanted materials, to help reduce friction and abrasion, or simply for aesthetic reasons. For protection from external factors or the option of numerous color sections, PVC may be your best choice. For protection from friction, Nylon may be better. Please contact the knowledgeable sales staff at NCA for advice.
What is fused cut and why might I want that option?
Fused cut cable or wire rope has been cut electronically rather than mechanically. This process is utilized to "fuse" the ends of the wires together thereby ensuring the ends of the wire rope will not come apart and fray. If you plan on not employing an end fitting, you may want to consider the fuse cut option. NCA has the ability to do fuse cut up to 60' in length. Please discuss this option when speaking with our knowledgeable sales staff.
What is the best end fitting or terminal to meet my need?
The best end fitting for your cable or wire rope assembly is completely dependent on your ultimate use for your assembly. Are you connecting, lifting, hanging, reeling, or pulling something? Every cable or wire rope assembly has its own special use. While you know that use best, NCA knows the options best. Contact our sales staff and together we can arrive at your optimal solution.
Can I save money by using an alternate fitting or cable?
Absolutely! There are so many option with cable and wire rope selection as to type, strength, flexibly, and coating. End fittings equally have numerous options. The most expensive does not always equate to the best choice for your unique need. NCA's years of experience and knowledge can help you in the selection of the best options and pricing for your ultimate assembly or lanyard use. We understand that ultimately your satisfaction is directly correlated with the satisfaction of your customers. We will ensure you get the right assembly at the right cost.
How should I measure my wire rope assembly or lanyard?
That depends on the end fittings you will be using and the ultimate function of the wire rope assembly. Is the total length the most important or is the location of the eye within the end fitting. How does the size of the loop impact the final length of the assembly? NCA can help you determine the best measurement criteria for your wire rope assembly or lanyard.
Do cable assemblies fail? Why?
Yes, nothing last forever. However, if the cable or wire rope assembly was designed and constructed properly, you can significantly reduce the risk of failure. There are a number of reasons an assembly could fail: corrosion causes by a reaction to environmental factors such as salt water or unwanted substances; wear over long periods of stressful use; or the load is greater than the breaking strength of the wire. The accurate selection of wire strength and flexibility as well as correct coating, will drop the risk of failure immensely. NCA's sales staff can help you ask the right questions to minimize you risk.
What terms do you offer for shipping?
Most often it is collect although we are happy to prepay a national carrier and include the freight cost in your invoice.
What carriers do you use?
