About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-30S
The AirTAC SAIJ160X900-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 870-900 mm, allowing you to dial back the 900 mm nominal stroke by up to 30 mm during commissioning. Fitted with a SUS304 stainless steel rod and a PT tapered port, it delivers a robust 14074 N pull force at 0.7 MPa.
This adjustable design eliminates the need to swap cylinders or add external stops when tuning end positions. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-30S Is Used
Long-Stroke Changeover
Set variable end-stops on automated lines to handle different product lengths without physically swapping out the long 900 mm cylinder.
Commissioning Tuning
Fine-tune the exact retract position within the 870-900 mm window during machine setup to perfect timing and avoid mechanical hard stops.
Heavy Positioning
Move heavy fixtures using the 14074 N pull force while relying on the rear screw to dial in the precise end-of-stroke location.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX900-30S the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust that exceeds the 5497 N push force of a 100 mm cylinder at 0.7 MPa, but want to avoid stepping up to the 21991 N of a 200 mm bore. The 30 mm adjustment window is ideal for product-size changeovers on long-stroke lines, letting you set a variable end-stop without changing the mounting footprint. Because the 900 mm stroke is substantial, an external guide is recommended to prevent side-loading on the extended rod.
For an exact ISO 15552 replacement, match the 160 mm bore, 900 mm stroke, 30 mm adjustment, PT G3/4 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-stop holding, use a 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 SAIJ160BX900-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of pull force and 14074 N of push force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 900 mm nominal stroke by up to 30 mm, creating a usable travel window of 870-900 mm. This stopper sets the retract end position but does not lock the load without continuous air pressure.
