About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-30
The AirTAC SAIJ32X35-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position without adding external stops. With a nominal 35 mm stroke and a 30 mm adjustment range, it provides a usable travel window of 5 to 35 mm. It delivers 402 N of push force at 0.5 MPa, making it well-suited for compact, low-force positioning tasks.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for position sensing. The rear adjuster acts purely as a mechanical stop to dial in the retract position during commissioning.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-30 Is Used
Machine Changeovers
Dial in the exact retract position within the 5-35 mm window during product size changes without swapping the physical cylinder.
End-Stop Calibration
Fine-tune the final resting position of small actuators in assembly fixtures where a fixed 35 mm stroke would be too rigid.
Compact Positioning
Utilize the 402 N push force and stainless SUS304 rod for light-duty, corrosion-resistant positioning in tight machinery layouts.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX35-30 the Right Cylinder?
Choose this 32 mm bore unit when your application requires precise end-position tuning at setup or during product changeovers, avoiding the need to physically swap cylinders. If your process requires slightly higher force, stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if you need a fixed, non-adjustable travel, the standard SAI series is a simpler alternative.
Because this is a double-acting cylinder, the rear adjuster only sets the travel end and does not hold the load without live air. For load-holding requirements without continuous pneumatic pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. This SAIJ model supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32BX35-30 FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 30 mm. This creates a usable stroke window of 5 to 35 mm, allowing precise end-position tuning at commissioning without external stops.
At an operating pressure of 0.5 MPa, the SAIJ32X35-30 provides a push force of 402 N and a pull force of 345 N. It can deliver up to 724 N of push force at 0.9 MPa.
