About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50
The AirTAC SAIJ160X900-50 is a double-acting ISO 15552 profile cylinder engineered with a rear stroke adjuster, providing a usable travel window of 850 to 900 mm. Designed for heavy-duty tasks, it delivers 10053 N of push force at 0.5 MPa. The 40 mm SUS420J2 stainless steel rod handles high side loads, while the PT G3/4 port ensures adequate air volume for movement within the 30-500 mm/s speed range.
This model features an external rear stopper that fine-tunes the retract end position during commissioning without requiring cylinder replacement. The adjuster acts purely as a travel stop and does not hold the load without live air. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU lacks a magnet for CMSE or DMSE switches.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50 Is Used
Heavy Press Tuning
Dial in the exact 850-900 mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Pallet Changeover
Adjust the retract position on the fly for different pallet sizes on a transfer line, using the rear stopper to set the precise travel window.
Large Fixture Setup
Fine-tune the end position of large automated fixtures, leveraging the 10053 N push force to move heavy loads accurately into place.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX900-50 the Right Cylinder?
Choose this 160 mm bore when an application requires the 10053 N push force at 0.5 MPa, stepping up from a 125 mm bore that provides 6136 N. An adjustable stroke is ideal for product changeovers on a line, allowing you to dial in the exact 850-900 mm end-stop without adding external stops. For load-holding without live pressure, select a SAIL or BSAI cylinder, as the rear adjuster here is not a lock. Because the stroke is 900 mm, an external guide is strongly recommended to prevent excessive rod side-loading.
To match this ISO 15552 interchangeable cylinder exactly, specify: 160 mm bore, 900 mm stroke, 50 mm adjustment, PT G3/4 port, SUS420J2 rod material, no magnet, and a supported mounting style like TC or LB.

- ✓ 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 SAIJ160AX900-50 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At a maximum 1.0 MPa, it achieves 2050 kgf.
The rear adjuster screw allows you to trim the effective stroke by up to 50 mm, creating an adjustable travel window between 850 mm and 900 mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
