About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-30
The AirTAC SAIJ160X900-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 870 to 900 mm, allowing you to dial back the nominal 900 mm stroke by up to 30 mm during machine setup. This bore size delivers massive thrust, generating 18095 N of push force at 0.9 MPa.
Built with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, this unit is tailored for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, so external physical stops are required if position sensing is needed.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-30 Is Used
Heavy Press Tuning
Fine-tune the exact end-of-stroke contact point on a 900 mm forming press without machining new external stopper blocks.
Product Changeover
Quickly adjust the 870-900 mm travel window to accommodate different pallet sizes on a heavy-duty transfer line.
Long-Stroke Assembly
Drive large components over a 900 mm span while using the 30 mm rear stopper to compensate for mechanical tolerance stack-up.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-30 the Right Cylinder?
Choose this 160 mm bore when 100 mm bore caps out at 7068 N push at 0.9 MPa, but stepping up to 200 mm bore yields 28274 N. The adjustable rear stopper is ideal for fine-tuning end positions at commissioning without adding external stops, unlike a fixed-stroke SAI cylinder. To match this replacement exactly, specify the 900 mm stroke, 30 mm adjustment, PT ports, no magnet, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 900 mm, the 40 mm diameter rod and M36x2 thread can carry significant side loads, but an external guide is strongly recommended to prevent rod binding. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, use an SAIL or BSAI cylinder.
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 SAIJ160AX900-30 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 14074 N at 0.7 MPa. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that can shorten the effective travel by up to 30 mm, giving an 870 to 900 mm usable stroke window. It sets the end position but does not lock or hold the load without continuous air pressure.
