About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-50
The AirTAC SAIJ160X600-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This yields a usable end-position window of 550 to 600 mm, letting you dial in the exact retract distance during commissioning without swapping out the barrel or adding external mechanical stops. It delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa.
This unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance, uses a PT tapered port thread, and lacks a piston magnet. The extruded aluminum barrel incorporates sensor grooves on both sides, though fitting CMSE reed or DMSE electronic sensors requires a magnet-equipped variant. The rear adjuster acts purely as a travel stop to set the end position; it does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-50 Is Used
Heavy Press Tuning
Fine-tune the 550-600 mm retract stop on a large press to accommodate varying material thicknesses without repositioning the entire cylinder assembly.
Pallet Positioning
Adjust the end-of-stroke position on the fly during product size changeovers on a heavy-duty conveyor line, saving setup time.
Large Assembly Jigs
Dial in the exact clamping distance on large-scale assembly jigs where a fixed 600 mm stroke would be too rigid for varying part dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-50 the Right Cylinder?
Choose this 160 mm bore when your application requires high force in the 9000 to 18000 N range at standard plant pressures, but you need the flexibility to fine-tune the retract end-point for product changeovers. If you need less force, stepping down to a 100 mm bore yields 5497 N of push force at 0.7 MPa. If you require more, a 200 mm bore provides 21991 N. Because this cylinder features a 600 mm stroke, you must account for rod side-loading; an external guide is recommended to prevent eccentric wear on the 40 mm diameter rod and M36x2 thread.
When specifying an ISO 15552 replacement, match the 160 mm bore, 600 mm nominal stroke, 50 mm adjustment range, PT port thread, and SUS304 rod material. Remember that the rear adjuster only sets the travel end and relies on the variable air cushion for deceleration; it is not a holding brake. For true load-holding without live air, select an SAIL pneumatic lock or BSAI clamp-lock cylinder instead of this SAIJ model. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ160BX600-50 FAQ
It uses a rear external stopper screw that lets you shorten the nominal 600 mm stroke by up to 50 mm, providing a usable travel window of 550 to 600 mm. This allows precise end-position tuning at commissioning without replacing the cylinder.
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 18095 N of push force.
