About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-50S
The AirTAC SAIJ160X700-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 650 to 700 mm for precise end-position tuning during commissioning. Built with a SUS304 stainless steel rod (code B) and a -S magnet for CMSE reed and DMSE electronic sensors, it delivers robust performance in demanding environments. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
Delivering substantial thrust, this 160 mm bore generates 14074 N of push force at 0.7 MPa. The rear stopper mechanism allows you to dial back the stroke by up to 50 mm without swapping the cylinder or adding external stops. It operates at speeds of 30-500 mm/s and uses a G3/4 PT tapered port, ensuring high flow capacity for heavy-duty actuation.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-50S Is Used
Heavy Machinery Setup
Fine-tune the 650-700 mm travel end-position during large equipment commissioning without machining external stoppers.
Product Size Changeover
Quickly dial the rear adjuster up to 50 mm to accommodate different product lengths on an automated line.
High-Force Positioning
Leverage 14074 N of push force at 0.7 MPa for moving substantial loads while maintaining precise end-stop control.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-50S the Right Cylinder?
Selecting this 160 mm bore makes sense when an application requires heavy force, such as 14074 N push at 0.7 MPa, alongside variable end-stop positioning. If your setup demands less thrust, stepping down to a 125 mm bore yields 8590 N at the same pressure, whereas moving up to a 200 mm bore provides 21991 N. The adjustable stroke is ideal for product-size changeovers on a line, allowing operators to fine-tune the 650-700 mm travel window quickly instead of machining new hard stops.
Because the stroke is 700 mm, the 40 mm diameter rod and M36x2 thread still require external guidance to prevent excessive side-loading on the piston. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX700-50S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At 0.5 MPa, the push force is 10053 N.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from the nominal 700 mm down to 650 mm. It is a travel stop, not a lock, and the cylinder remains double-acting.
