About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-40
The AirTAC SAIJ32X135-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 95-135 mm usable travel window, allowing you to trim the nominal 135 mm stroke by up to 40 mm during commissioning without swapping the cylinder.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-800 mm/s and uses a PT G1/8 port.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-40 Is Used
Machine Changeover
Quickly dial in the 95-135 mm travel window during product size changes on a packaging line without replacing the cylinder.
End-Position Tuning
Fine-tune the exact retract distance at commissioning to prevent mechanical crashes, using the 40 mm adjustment screw.
Variable End Stops
Ideal for assembly stations needing flexible positioning limits within a compact 32 mm bore footprint.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-40 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops or fine-tuning on the fly, avoiding the need to bolt on external stops or buy a fixed-length SAI cylinder.
Because this unit lacks a magnet (-S), it cannot host CMSE or DMSE sensors without modification. Remember that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air. For positive load-holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 Adjustable Cylinder SAIJ32 SAIJ32AX135-40 FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 135 mm down to as little as 95 mm. It sets the travel end but does not lock the load without continuous air pressure.
