About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-75
The AirTAC SAIJ160X220-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers heavy thrust, pushing with 14074N at 0.7 MPa and pulling with 9425N at 0.5 MPa. The built-in rear stopper screw allows you to fine-tune the end position at commissioning, providing a usable travel window of 145 to 220 mm without adding external stops.
This unit is configured with a SUS304 stainless steel rod (code B) for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches if needed later. It uses variable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-75 Is Used
Multi-Product Forming
Dial the stroke back from 220 to 145 mm to accommodate varying material thicknesses on a single heavy-duty press without swapping tooling.
Commissioning Tuning
Fine-tune the retract end-position during machine setup to perfect timing sequences, using the rear screw instead of adding external stopper blocks.
Heavy Assembly Lines
Leverage the 14074N push force at 0.7 MPa to move heavy pallets, adjusting the travel window easily when conveyor widths change.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-75 the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (5497N push at 0.7 MPa) is too small, but you want to avoid stepping up to a massive 200 mm body. The 75 mm adjustment range is selected over a fixed-stroke SAI when a machine handles multiple product sizes, letting operators dial in the retract end-position precisely. Remember the rear adjuster acts only as a travel stop; it does not hold the load without live air. For fail-safe load holding, use an external rod lock or pilot-operated check valve.
To match this ISO 15552 replacement, specify: 160 mm bore, 220 mm stroke, 75 mm adjustment, PT tapered G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet. Because the 220 mm stroke is relatively short for this large bore, side-load risks are minimal, but always guide the rod end on long unsupported setups.
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 SAIJ160 Adjustable Cylinder SAIJ160BX220-75 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074N and a pull force of 9425N. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 220 mm stroke by up to 75 mm, creating a usable travel window of 145 to 220 mm. It functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
