Assembly example with key and axial set screw.

Elesa® original design technopolymer plastic solid disk handwheels.  
Designed for applications where it is necessary for the handle to return back to starting position after operation for safety reasons or lack of space.  
In order to bring the handle into the operating position, it has to be pulled upward 90° towards the rim to a stop against a torsion spring, and then it is pushed against spring pressure into its hold position.  
By maintaining the forward thrust on the handle, the handwheel can easily be rotated.  
When releasing the handle, the spring automatically returns it back to the retracted position.    
Handwheel features rear finger grips.  
Resistant to solvents, oils, grease and other chemical agents. Temperature resistant up to 80° C (176° F).
Countersunk washers for handwheel retention, see GN 184.5. Other modifications such as special inch or metric bores, set screw holes, etc. available upon request.

See our technical section for bore sizes, other modifications and tolerances.
