The Differences & Benefits of Swaged vs. Shuttled Molded Conduit Fittings
Cable assemblies consist of two main components: a cable, the tightly wounded bundles of wire, and a conduit, the protective tubing or sleeve that surrounds the cable. Many applications require a conduit to preserve the integrity of the wire …
Understanding Cable Bend Radius To Prevent Damage
Mechanical cables require an understanding of how bend radius can influence cable integrity, fatigue, and service life. Estimating the bend radius of a cable before installation will help establish parameters for optimal performance.
The bend radius determines how tight a cable can be bent …
Push-Pull and Pull-Pull Controls Design Guide
There are many common, everyday applications that use efficient and reliable CMA controls. These applications include
automotive seat releases, lawn mower throttle controls, and airplane seat back controls. Some uses of controls are obvious and visible, while others are not. Simple and lightweight controls for dependable, …
The CMA “Cycle-Flex™ Design Guide” is a comprehensive reference of design considerations for the specification of Cycle-Flex miniature cables. Some of the topics covered in this Guide include:
What is Cycle-Flex cable
How stretch and breaking strength should be considered during the design phase
How Cycle-Flex’s strength requirements differ from general …
The CMA “General Applications / Safety & Restraint Design Guide” is a comprehensive reference of design considerations for the specification of general use cables and cable assemblies. Some of the topics covered in this Guide include:
How wire rope and cables are fabricated
How stretch and breakage should be considered …
Review full definitions of terms such as ‘cable tensile strength’, ‘lost motion’, ‘travel dimension’ and more. Understand ‘conduit’ and ‘conduit fittings’ options in further detail.
Considering Design Factors of Lost Motion
Mechanical control cables provide a simple, lightweight, economical, and reliable way to activate throttles, latches, gas springs, electromechanical devices, and many other mechanisms.
The basic design of mechanical control cables features a movable core that’s free to travel axially inside a conduit. Actuating a lever …
CMA’s Cycle-Flex is recommended for rigorous, high cycle life cable applications. It is a lubricated stainless steel strand coated with a very flexible, abrasion resistant nylon.
Depending upon load consideration cable stretch, both constructional and elastic, needs to be considered. Constructional stretch can be removed; elastic stretch can …
These are really a subset of Push/Pull and Pull Pull cables.
CMA has available a large number of operators and actuators suitable for use in a variety of applications including Gas springs.
Using an integral return spring in the actuating mechanisms allows the use of a pull/pull cable …
Using an integral return spring in the actuating mechanisms allows the use of a pull pull cable assembly.
In general, a more flexible conduit and cable construction will allow for tighter routings and smaller bend radii.
Because of the frictional forces between the cable and the conduit, …
