About the Airtac SAI32 Standard Cylinder SAI32X535
The AirTAC SAI32X535 is a double-acting ISO 15552 profile cylinder featuring a 32mm bore and a 535mm stroke. Because this stroke exceeds the standard 500mm limit for this bore, it is produced as a non-standard made-to-order unit. It generates 402N of push force and 345N of pull force at 0.5 MPa, making it suitable for light-duty positioning tasks.
This actuator utilizes an extruded aluminum barrel without tie rods and includes sensor grooves on both sides for CMSE or DMSE switches (requiring a magnet). The standard piston rod is carbon steel, and the seals are TPU. It operates at speeds between 30 and 800 mm/s and features adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI32 Standard Cylinder SAI32X535 Is Used
Light Assembly Automation
Provides 402N of push force at 0.5 MPa, ideal for driving small linear slides or pushing light components into position on an assembly line.
Package Diversion
The 535mm stroke offers extended travel to push small cartons or totes across a conveyor belt junction without requiring a multi-stage actuator.
Testing Fixture Movement
Moves testing probes or sensors into position across a wide testing bed, utilizing the adjustable air cushions to ensure gentle contact at the stroke end.
Is the Airtac SAI32 Standard Cylinder SAI32X535 the Right Cylinder?
This 32mm bore yields 402N of thrust at 0.5 MPa. If your application requires less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore provides 628N. At 535mm, the stroke is non-standard and requires custom manufacturing. Because the stroke exceeds 300mm, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature rod-bearing wear.
This profile cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 actuators. To match this exact unit, specify the 32mm bore, 535mm stroke, PT tapered port thread, and the desired mounting accessory (such as an LB foot or TC trunnion). A magnet (-S) is not specified for this configuration.
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.
Airtac SAI32 Standard Cylinder SAI32X535 FAQ
The SAI32X535 generates 402N of push force and 345N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 563N.
No, a standard SAI cylinder does not hold its position when air pressure is removed or exhausted; the piston will drift. The adjustable cushion only decelerates the piston near stroke end, it does not act as a lock. For position holding without live pressure, consider the SAIL or BSAI variants.
