About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-30S
The AirTAC SAIJ32X750-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel window to 720-750 mm. It delivers a 0.7 MPa push force of 563 N and includes a SUS304 stainless steel rod for superior corrosion resistance. Equipped with a magnet, it supports CMSE reed and DMSE electronic sensors mounted in the dual-side barrel grooves.
This adjustable-stroke variant uses an external rear stopper screw rather than a lock to set the retract end position. It shares the exact ISO 15552 mounting interface of the fixed-stroke SAI series but utilizes a reduced mounting set comprising Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-30S Is Used
Machine Setup Fine-Tuning
Dial in the exact 720-750 mm retract position during initial commissioning without machining external stop collars.
Product Size Changeover
Quickly adapt the end-of-stroke position on a packaging line when switching to a different product length.
Variable End-Stop Positioning
Use the rear adjuster screw to set precise end positions for light assembly tasks requiring 402 N at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-30S the Right Cylinder?
Choose this 32 mm bore when you need 563 N of thrust at 0.7 MPa and a variable end-stop for product changeovers. If your application requires higher force, stepping up to the 40 mm bore yields 879 N at the same pressure. The 30 mm adjustment window allows precise commissioning without swapping the cylinder or adding external stops.
Because the 750 mm stroke is long relative to the 12 mm rod diameter, external guidance is recommended to manage side loads. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, consider the SAIL or BSAI series. This unit features PT tapered ports and operates at speeds of 30-800 mm/s.
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 SAIJ32BX750-30S FAQ
At 0.7 MPa, the 32 mm bore provides a push force of 563 N and a pull force of 345 N at 0.5 MPa. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a stopper to shorten the 750 mm nominal stroke by up to 30 mm, creating a 720-750 mm usable travel window. It only sets the end position and does not lock the load without live air.
