Mechanical assembly

Understanding the benefits

From custom crimps and threaded fittings to midsection attachment points and end terminations, mechanical assemblies enable wire-based products to meet the needs of complicated applications. Our integrated operations allow you to streamline your manufacturing process, knowing that your custom parts will arrive just the way you need them.

Typical end uses

When you're designing a custom mechanical assembly, you define the end uses. We've seen our customers put their designs to work in:

• Articulation devices
• Laparoscopic or robotic surgery devices
• Minimally invasive surgical instruments

Design specifications

Mechanical assemblies can be as basic as selecting the treatment to the ends of cut to length strands and cables, or as complicated as customer terminations and midsection fittings.

Strands and cable end options

If you're trying to find the best strand or cable for your application, you can learn more about different alloys and constructions here. When you need those strands or cables cut to length, we use the following end options to ensure they arrive ready for use.

• Bead and swage
• Beaded
• Encapsulated (rounded)
• Fused
• Shear

Mechanical assembly components

To make choosing the right components for your assembly easier, you'll find information about different fittings below to help you prepare for a conversation with our New Product Development engineering teams.

	Ball Provides 60% of cable breaking load
	Ball and shank Provides full breaking load of cable Allows for attachments within a spherical pocket Allows cable rotation when load is not significant Shank provides abrasion protection
	Clevis ends Are manufactured in a fork or eye configuration Provide attachment point using a cross pin where push and pull may be needed
	End stops Provide a secure attachment point Can be attached to the middle of a cable if pulling is expected in two directions Are configured to yield a breaking load that approaches the breaking load of the cable to which they are attached Provide close tolerance on swaged diameter to allow for precision placement into a pocket or bore Button ends offer the most compact fitting to achieve near full cable breaking load Fittings are normally factory swaged
	Flanged stop Intended for use at end of cable Beneficial when cylindrical end stop does not provide enough shoulder Eliminates need for washer to prevent pull-through
	Hexagonal or square end stops Provide attachment points Offer larger dimensions Can be provided as an accompaniment to cable assemblies with factory applied fittings
	Radiused end stops Centers with a bore or pocket Offers holding strength to full breaking load of cable Allows for cable rotation and positioning
	Threaded fittings Allow for secure attachment and adjustability Shank and thread diameter customizable Can be used to precisely set tension Adjustable to remove cable slack

Additional processing capabilities

Our mechanical assemblies can be further customized with additional processing, such as:

• Coating to provide electrical insulation or chemical separation
• Laser ablation for customized coating coverage
• Electro discharge machining to create precise lengths
• Grinding to create flush ends of crimped assemblies
