About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-50
The AirTAC SAIJ160X700-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial the effective travel back by up to 50 mm. This yields a usable 650-700 mm stroke window, letting you fine-tune the retract end position at commissioning without adding external stops. It delivers substantial thrust, generating 14074 N of push force at 0.7 MPa.
This large-bore unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Remember that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-50 Is Used
Variable End-Stops
Set precise retract positions within the 650-700 mm window during machine commissioning without physically swapping the cylinder.
Product Changeover
Quickly re-tune the stroke length on automated lines when processing different product sizes or thicknesses.
Heavy Forming Setup
Dial in the exact end-position for high-force pressing or forming operations using the 14074 N push capacity at 0.7 MPa.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-50 the Right Cylinder?
Choose this 160 mm bore when you need higher force than a 125 mm bore (which provides 8590 N push at 0.7 MPa) but less than the maximum 200 mm class. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, functioning differently from a fixed-stroke SAI cylinder by allowing quick repositioning. For this 700 mm stroke, the 40 mm rod diameter handles significant side loads, but an external guide is still recommended for unsupported loads. If true load-holding without live air is required, select the SAIL or BSAI series instead, as this adjuster is not a lock. ISO 15552 replacement match: 160 mm bore, 700 mm stroke, 50 mm adjustment, PT G3/4 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, no magnet.
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 SAIJ160BX700-50 FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push of 18095 N at 0.9 MPa.
The rear adjuster is an external stopper that lets you shorten the nominal 700 mm stroke by up to 50 mm, creating a 650-700 mm usable travel window. It sets the travel end for deceleration but does not lock or hold the load without continuous air pressure.
