About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-10S
The AirTAC SAIJ160X250-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the stroke by up to 10 mm. This yields a precise 240-250 mm usable travel window, ideal for fine-tuning end positions during commissioning without adding external stops. It delivers substantial thrust, pushing 14074 N and pulling 9425 N at 0.7 MPa.
Built with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread, this 160 mm bore actuator runs at 30-500 mm/s. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet interfaces directly with AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-10S Is Used
Heavy Press Tuning
Dial in the exact 240-250 mm end position during machine commissioning to prevent over-travel on heavy pressing tasks without external stopper blocks.
Product Changeover
Quickly adjust the retract stop by up to 10 mm on automated lines when switching to a slightly shorter product variant, minimizing downtime.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod and 14074 N push force to drive robust assembly operations in environments requiring high corrosion resistance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-10S the Right Cylinder?
Select this 160 mm bore actuator when a 125 mm cylinder (providing 8590 N push at 0.7 MPa) lacks the required force, but stepping up to a 200 mm bore would be excessive. The 10 mm rear adjustment screw is invaluable for product changeovers, letting you shift the retract end-stop on the fly instead of physically swapping the cylinder. For any application needing 250 mm of travel or more, always pair the cylinder with an external guide to handle side loads, as the M36x2 rod thread alone cannot support off-center loads.
When specifying an ISO 15552 replacement, match the 160 mm bore, 250 mm stroke, PT ports, and the -S magnet requirement. Remember that the rear adjuster functions strictly as a travel stop and the air cushions only manage deceleration; neither will hold a load without live air pressure. If your setup requires true load-holding on air loss, utilize an external rod lock or select the AirTAC SAIL or BSAI series instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160BX250-10S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. At its maximum 1.0 MPa pressure, it achieves a push force of 18095 N.
The rear mechanical adjuster acts as a stopper that can shorten the nominal 250 mm stroke by up to 10 mm, creating a 240-250 mm usable travel window. It is a travel stop for fine-tuning end positions, not a lock, and cannot hold the load without continuous air pressure.
