EHTC TELESCOPING PNEUMATIC CYLINDERS

 


Since our inception in 1992, Ergo-Help has reigned as the unsurpassed industry leader in the manufacturing of lightweight, multiple-stage, space-saving telescopic air cylinders.  

  Our patented EHTC telescoping cylinder design enables each stage to retract fully into its base, flush with the front cap, allowing for the most compact retracted unit per each stage's stroke currently available on the market. 

We don't just stop there.  We could configure up to nine stages in our telescoping cylinder designs, by far surpassing the industry standard maximum of three to four stages. 

4" retracted

20" stroke

8 stages

 

 
         SINGLE-ACTING

Together, these attributes bill our product as the first choice for applications where maximum stroke must be paired with minimum retracted length.

  

 Compact & Lightweight

    • hollow pistons
    • nested end caps
    • aluminum alloy construction 

Resilient

    • moisture tolerant  
    • chemical resistant
    • indoor/outdoor applications
    • fully serviceable

Versatile

    • single or double-acting
    • custom-designed stroke, retracted length, and force
    • wide temperature tolerances (-10 to +200 deg. F)
    • variety of mounting configurations (front/rear flush, base, side, front/rear trunnion, rear pivot) 

 

 

Here are some of our EHTC multi-stage cylinders in action: 

   


 

Below is technical data on our 1 inch bore EHTC single and double-acting telescoping cylinders.

This is only a sample of the available bore and port sizes, stroke and retracted lengths, force ratings, and number of stages.
