About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-30
The AirTAC SAIJ32X700-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 30 mm. This creates a highly useful 670-700 mm usable stroke window, letting you dial in the exact end position during commissioning without adding bulky external stops. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa operating pressure.
Built with a SUS304 stainless steel rod (code B) and tapered PT ports, this model is tailored for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed and DMSE electronic sensors if you decide to add a magnet later. Variable air cushions at both ends help manage deceleration across the 700 mm travel.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-30 Is Used
Machine Changeover
Fine-tune the 670-700 mm end-stop on the fly when switching product sizes on an assembly line, avoiding the need to physically swap out a long-stroke cylinder.
Variable End Stops
Dial in the exact rejection distance for diverter arms on a conveyor without installing secondary external stopper blocks along the 700 mm travel path.
Commissioning Calibration
Perfectly align tooling end positions during initial machine setup by trimming up to 30 mm off the nominal stroke, compensating for mechanical tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-30 the Right Cylinder?
Choose this 32 mm bore when you need precise positioning in a compact footprint but require a longer 700 mm travel. If your application needs more thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The integrated rear adjuster is a major advantage over a fixed SAI cylinder for machine setups that require fine end-position tuning or frequent product changeovers.
Because the stroke is 700 mm, the 12 mm rod is susceptible to side-loading; always use an external guide to prevent binding. Remember that the rear adjuster functions only as a travel stop, not a lock. The cylinder will not hold its load without live air pressure, so for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. This unit is dimensionally interchangeable per ISO 15552 and uses PT porting.
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 SAIJ32BX700-30 FAQ
At a 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.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 700 mm stroke by up to 30 mm, providing a 670-700 mm usable travel window. It only sets the end position; it does not lock or hold the load without continuous air pressure.
