About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-100
The AirTAC SAIJ160X425-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stopper for precise stroke trimming. It provides a usable travel window of 325 to 425 mm, allowing you to dial in the exact retract position without swapping hardware. Built with a SUS304 stainless steel rod, it generates 14074 N of push force at 0.7 MPa.
This heavy-duty actuator uses PT tapered ports and variable air cushions at both ends to manage kinetic energy. The rear adjuster acts strictly as an end-position stop for commissioning and product changeovers; it does not lock the load without live air pressure. For position holding without continuous air, an external rod lock or related SAIL lock variant is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-100 Is Used
Heavy-Duty Forming Press
Dial in the exact 325 to 425 mm retract position during press setup to accommodate different die heights without installing external mechanical stops.
Pallet Diverting
Provides 14074 N of push force at 0.7 MPa to route heavy pallets, with the rear adjuster allowing quick changes to the diverting end-point as pallet sizes vary.
Large Assembly Fixture
Uses the SUS304 stainless steel rod for corrosion resistance in demanding environments while fine-tuning the clamping travel window during product changeovers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-100 the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application requires substantial thrust, such as 14074 N push force at 0.7 MPa, combined with variable end-stop positioning. If your setup needs less force, stepping down to a 125 mm bore yields 8590 N push force at the same pressure. Because this model features a 425 mm stroke, the 40 mm rod diameter and M36x2 thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on the piston over long unsupported travels.
The adjustable stroke is ideal for production lines handling varying product sizes, letting you fine-tune the retract distance on the fly instead of adding external stops. When matching ISO 15552 dimensions for a replacement, verify the 425 mm nominal stroke, 100 mm adjuster range, PT port thread, and the reduced SAIJ mounting set which includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that this SKU does not include a magnet for CMSE or DMSE sensors.
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 SAIJ160BX425-100 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the nominal 425 mm stroke by up to 100 mm, creating a usable travel window of 325 to 425 mm. This stopper only sets the end position and does not hold the load without live air pressure.
