Technical Ratings & Specifications

ARO Series S Silverair™ Cylinders: The Industry Standard for Disposable Pneumatic Reliability

In the world of automated manufacturing and fluid management, system uptime is dictated by the smallest components. The ARO Series S Silverair range is engineered to provide high-cycle reliability in light-duty applications where a cost-effective, disposable solution is preferred. By merging a corrosion-resistant stainless steel body with lightweight aluminum heads, ARO has created a cylinder that balances performance, longevity, and affordability.

Engineered Resilience for Corrosive Environments

Standard "throwaway" cylinders often fail due to internal oxidation or rod seizing. The Series S overcomes these hurdles through high-grade material selection:

• 304 Stainless Steel Barrels: Unlike aluminum-bore cylinders, the Series S features a drawn and polished 304 stainless steel barrel. This provides a harder, smoother surface that resists scoring and provides superior lube-holding characteristics.

• 303 Stainless Steel Piston Rods: Every Silverair cylinder comes standard with a centerless ground and polished 303 stainless steel rod, ensuring smooth reciprocating motion even in damp or wash-down conditions.

• Roll-Formed Threads: Piston rod threads are roll-formed rather than cut, resulting in a stronger molecular structure and increased resistance to fatigue and stripping.

• Lightweight Aluminum Heads: Full-flow ports allow for maximum airflow and rapid response times.

U-Cup Technology: Redefining Sealing Logic

The Silverair Series S utilizes a U-cup packing design for both the piston and rod seals. While competitors often use standard O-rings to save costs, ARO’s U-cup geometry offers:

• Lower Breakaway Friction: The "lips" of the U-cup require less air pressure to begin movement, ensuring a crisp, immediate response.

• Wear Compensation: As the seal wears over millions of cycles, the U-cup naturally expands under pressure to maintain a tight seal, significantly extending the service life compared to traditional O-rings.

• Reduced Blow-By: The continuous contact design minimizes air leakage, optimizing your compressor’s energy efficiency.

Maintenance-Free "Set and Forget" Design

Every Silverair cylinder is factory pre-lubricated. This makes them the ideal solution for systems where external lubrication is either impossible to reach or prohibited (such as in food packaging or electronics assembly).

Technical Performance Summary

• Bore Sizes: 1/2” to 2-1/2” (Small to Medium Bore)

• Operating Pressure: Up to 200 PSI (14 bar)

• Max Output Force: 982 lbs (at 2-1/2" Bore)

• Temperature Range: -40°F to 160°F (-40°C to 71°C)

• Lubrication: Prelubed for non-lubricated service.
