Series S Silverair Pneumatic Cylinders Information

Features & Benefits

Why Choose ARO Silverair Series S?

The Silverair Series S is the "workhorse" of the disposable cylinder world. It is designed for businesses that need high-quality pneumatic motion without the high cost or maintenance of repairable cylinders.

The ARO Advantage: Maintenance-Free Operation

No Lubrication Required: Every cylinder comes pre-lubricated from the factory. It’s the perfect solution for "clean" environments or remote locations where adding oil to the air line isn't feasible.
Built for Longevity: With roll-formed piston rod threads and oil-permeated bronze bushings, these cylinders are engineered to endure millions of cycles.
Corrosion Ready: The combination of an aluminum body and stainless steel internals means these cylinders won't rust or seize in damp or chemical-heavy workspaces.

Versatile Mounting & Action Options

Tailor your cylinder to your exact machine footprint with a wide variety of mounting styles:

Nose Mount: Standard for simple through-hole installations.
Universal/Pivot Mount: Ideal for applications requiring a range of motion.
Block Front Mount: Perfect for tight spaces and rigid mounting.
Double Rod End: For tasks requiring simultaneous motion on both sides.

Configuration Styles

Spring Return & Spring Extend (Single-Acting)

Best For: Fail-safe applications where the rod must return to a home position.
The Advantage: High-tensile alloy springs provide exceptional performance over a long service life. Available in Nose, Universal, and Block Front mounts.

Double-Acting (Standard & Non-Rotating)

Best For: Precise, powered control in both directions.
The Advantage: Available in strokes up to 12 inches. The Non-Rotating (SH) variant is specifically optimized for applications requiring fixed orientation without external guides.

Double Rod End (Model SD)

Best For: Dual-end mounting and synchronized movement requirements.

Specialized Design Options

Magnetic Pistons: Available for integration with Hall Effect or Reed Switches, allowing your PLC to monitor the exact position of the piston for complex automation sequences.
Bumper Options: Optional internal bumpers reduce the noise and vibration associated with high-speed cycling, protecting both the cylinder and your machine frame.
