About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-40S
The AirTAC SAIJ32X210-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 170 to 210 mm usable travel window, allowing you to dial back the nominal 210 mm stroke by up to 40 mm during commissioning. It delivers 402 N of push force at 0.5 MPa, matching the standard SAI force class for compact automation tasks.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and carries the -S magnet option for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, directly accepting AirTAC CMSE reed and DMSE electronic switches without extra brackets. The mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-40S Is Used
Machine Changeover
Dial in the 170-210 mm travel window during product size changes to set new end positions rapidly without changing the cylinder.
Variable End Stops
Use the 40 mm rear adjustment screw to fine-tune the retract end position during machine setup, avoiding external stop blocks.
Sensor-Ready Positioning
Leverage the integrated -S magnet and dual sensor grooves to mount CMSE or DMSE switches for exact retract confirmation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX210-40S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning without swapping hardware; the rear stopper lets you set variable end stops for product changeovers. If your process requires less force, stepping down is not an option below 32 mm, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select a SAIL or BSAI cylinder. This model uses PT tapered ports and is dimensionally interchangeable with ISO 15552 cylinders. At a 210 mm stroke, the 12 mm rod handles standard loads, but long unsupported strokes still need an external guide to prevent side-loading damage.
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 SAIJ32AX210-40S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 210 mm down to 170 mm. It trims the retract end position during commissioning but does not lock the load without live air pressure.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
