Airtac SC40X90S SC Series Tie-Rod Pneumatic Cylinder

Airtac SC40X90S SC Series Tie-Rod Pneumatic Cylinder

Model-specific summary: The Airtac SC40X90S is a double-acting SC Series standard tie-rod air cylinder with a 40 mm bore and 90 mm stroke, plus a magnetic piston for compatible position sensors. It is intended for repeatable linear extension and retraction in general industrial machinery.

Key specifications

Construction and operating advantages

• Front and rear covers are joined to the aluminum barrel by tie rods for a rigid, service-proven structure.
• The profiled two-way piston seal is compact and incorporates grease-retaining geometry.
• Air cushioning at both ends can be adjusted for smoother end-of-stroke deceleration.
• The SC body is shorter than an ISO 15552 cylinder of the same bore, while retaining conventional tie-rod construction.
• Multiple mounting accessories support foot, flange, clevis and trunnion-style machine layouts.
• The magnetic piston allows compatible sensors to be mounted on the cylinder tie rods for end-position feedback.
• High-temperature seal configurations are available at series level for operation up to 150 °C; this is not implied by the standard model code shown here.

Installation and commissioning

1. Size the cylinder with sufficient output margin for actual load variation; theoretical force alone is not the usable machine force.
2. Flush the air line before connection and supply air filtered to 40 μm or finer.
3. Protect the cylinder from heavy dust, water droplets, oil mist, weld spatter and freezing condensate.
4. During initial no-load testing, start with conservative cushion adjustment and open gradually to avoid excessive impact.
5. Avoid unsupported side load on the piston rod and verify alignment over the full 90 mm travel.

Quick selection answer

SC40X90S is a 40 mm bore, 90 mm stroke, double-acting standard pneumatic cylinder with a magnetic piston.

Typical applications

Suitable for packaging machinery, conveyors, clamping fixtures, material handling equipment and general industrial automation requiring linear motion.

Selection and compatibility notes

• Non-standard catalog stroke; 90 mm is within the SC40 maximum stroke range. Confirm made-to-order availability. The catalog pressure and speed limits do not replace application-specific force and kinetic-energy calculations.
• Confirm the complete model code, installation space and operating conditions before purchase.
• Product selection must be verified against the machine load, speed, duty cycle and safety requirements.

Frequently asked questions

What is SC40X90S used for?

Suitable for packaging machinery, conveyors, clamping fixtures, material handling equipment and general industrial automation requiring linear motion.

How does this model differ from related products?

Compared with a compact cylinder, the SC tie-rod design is better suited to longer strokes and conventional industrial mounting. Bore and stroke must still be sized from required force and travel.

What should be checked before ordering?

Check the model code, dimensions, operating conditions, mounting method and required accessories. Refer to the manufacturer catalog drawing for final engineering approval.
