Firestone Industrial Products debuted a new range of pneumatic actuators this week that consist of engineered-plastic molded elements welded together in a sealed unit.
Called the Polyactuator 70-P-13, the line has no pistons, rods, or sliding seals so friction, bending, scoring, and wear disappear as potential problems.
They take a small footprint too. Minimum height on the new models, says Firestone, is 0.6 inches (16mm), which means they can fit in very tight spaces.
The new models are capable of strokes up to 0.5 inches (13mm) and forces over 100 lbs (0.45kN) at a pressure of 50 psig (3.5 bar).
Firestone says its engineers have tested the product under laboratory conditions for millions of cycles. Result: no product failure or degradation in performance, the company reports.
