Accessories - Linear & Rotary Motion



	Linear Motion When inputs and/or outputs are linear it is most important that input/output mechanisms be well aligned with end rods of the control cable. Misalignment will affect the efficiency of the control and cause unnecessary wear and fatigue of materials. It is, therefore, usually advisable to compensate for slight misalignment through the use of ball joints and clevises or rod end bearings as shown. FT (front thread) end fittings are recommended for ball bearing controls.


	Rotary Motion This configuration provides for articulation by use of a swivel abutment. These suggestions are offered for the most efficient installation. a. Axis of sleeve should be midway between high point of travel and low point of travel of the lever. This insures equal articulation of the ball joint and uniformity of forces and stroke. b. Mid-position of lever should coincide with mid-position of stroke. c. Type RT (rear thread) fittings recommended for ball bearing controls.


	Rotary Motion This is an articulating configuration using a ball joint and clevis to connect to the lever. It is important to observe the following precautions in this arrangement: a. Axis of sleeve should be midway between high point of travel and low point of travel of the lever. This insures equal articulation of the ball joint and uniformity of forces and stroke. b. Mid-position of lever should coincide with mid-position of stroke. c. Articulation of ball joint should be minimal and not exceed ± 5ƒ. Lengths of components and position should be selected accordingly. d. Type FT (front thread) fittings recommended for ball bearing controls.
