About the Airtac SAI32 Standard Cylinder SAI32AX275
The AirTAC SAI32X275 is a double-acting ISO 15552 profile cylinder engineered to deliver 402 N of push force at 0.5 MPa, extending to 563 N at 0.7 MPa. Its 275 mm stroke is well-suited for mid-length linear actuation tasks requiring consistent motion control. The extruded aluminum barrel design omits tie rods, presenting a clean exterior that integrates easily into modern machinery.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced resistance to surface corrosion in humid environments. It utilizes PT tapered port threads, and because it lacks a built-in magnet, position sensing requires external reed or solid-state switches mounted to the barrel's dual-sided sensor grooves.

Where the Airtac SAI32 Standard Cylinder SAI32AX275 Is Used
Package Sorting
Handles mid-range diverting and sorting motions on packaging lines where a 275 mm stroke reliably pushes cartons between lanes.
Small Press Fixtures
Provides 563 N of clamping force at 0.7 MPa for holding lightweight components during machining or assembly operations.
Vertical Ejection
Elevates or ejects small finished parts from machining centers, utilizing the full 275 mm extension to clear the work area.
Is the Airtac SAI32 Standard Cylinder SAI32AX275 the Right Cylinder?
When sizing this actuator, stepping up to the 40 mm bore increases the 0.5 MPa thrust to 628 N for heavier payloads, while dropping to a smaller bore sacrifices too much force for a 275 mm extension. Because this stroke exceeds 300 mm, the unsupported rod length introduces a risk of bending under side loads; utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 profile cylinder, it serves as a direct replacement for other standard ISO 15552 actuators. To match this exact unit, specify a 32 mm bore, 275 mm stroke, PT G1/8 port, and the desired mounting accessory such as an LB foot or FA flange. Note that the standard double-acting design will drift if air pressure is lost; use the SAIL variant for pneumatic locking requirements.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
