About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-30
The AirTAC SAIJ32X190-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 190 mm stroke that can be fine-tuned down by up to 30 mm, creating a precise 160-190 mm usable travel window. Delivering 563 N of push force at 0.7 MPa, it is built around an extruded aluminum barrel with sensor grooves on both sides.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads with a G1/8 connection. The rear adjustment screw acts purely as a mechanical stop to dial in the retract end position during commissioning; it does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-30 Is Used
Commissioning Calibration
Dial in the exact 160-190 mm retract distance during machine setup to perfectly align picking heads without machining new stop blocks.
Product Changeover
Quickly adjust the end-of-stroke position by up to 30 mm on a packaging line when switching between slightly different product sizes.
End-Stop Trimming
Trim the effective travel window back from 190 mm to prevent over-travel on delicate assemblies, using the rear screw as a hard mechanical stop.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX190-30 the Right Cylinder?
Choose this 32 mm bore when an application demands exact end-position tuning without swapping cylinders or adding external stops. If your setup requires less force, stepping down is not an option below 32 mm, but stepping up to a 40 mm bore yields 879 N of push force at 0.7 MPa. For holding a load securely without continuous air pressure, a plain SAIJ is insufficient—consider the SAIL lock or BSAI clamp-lock series instead.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 190 mm nominal stroke, 30 mm adjustment range, PT G1/8 port, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the 190 mm stroke is under 300 mm, side-load stress is moderate, but always guide the load externally for optimal bearing life.
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 SAIJ32BX190-30 FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder generates 563 N of push force and 345 N of pull force at 0.5 MPa. It uses a G1/8 PT tapered port thread and operates at speeds between 30 and 800 mm/s.
The rear adjuster screw allows you to shorten the 190 mm nominal stroke by up to 30 mm, providing a usable travel window of 160 to 190 mm. This stopper fine-tunes the end position but does not hold the load without live air pressure.
