Description
Hollow Plunger design allows for both pull and push forces: This means the cylinder can be used to extend (push) or retract (pull) a load because the plunger has a hollow center that allows rods or cables to pass through.
Composite bearings increase cylinder life and sideload resistance: The use of composite materials in the bearings makes them more durable and able to handle loads applied at an angle (side loads) without excessive wear.
Hard-Coat finish on all surfaces resists damage and extends cylinder life: A hard-coat finish on the cylinder surfaces makes them more resistant to scratches, corrosion, and other wear, leading to a longer lifespan.
Floating center tube increases seal and product life: A floating center tube allows for slight misalignment without damaging the seals, which reduces leakage and extends the overall life of the cylinder.
Handles standard on all models: All models come equipped with handles for easier positioning and control.
Steel base plate and saddle for protection against load-induced damage: The base plate and saddle are made of steel for added strength and protection against damage caused by the forces exerted on the cylinder.
Integral stop ring prevents plunger over-travel and is capable of withstanding the full cylinder capacity: The stop ring prevents the plunger from extending beyond its intended limit, protecting the cylinder from damage even at its maximum operating force.
High Strength return spring for rapid cylinder retraction: A strong return spring ensures the plunger retracts quickly after the force is released.
