About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-30
The AirTAC SAIJ160X950-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 950 mm nominal stroke by up to 30 mm for a precise 920-950 mm usable travel window. It delivers substantial thrust, generating 10053 N of pull force and 14074 N of push force at 0.7 MPa. This bore size features a robust 40 mm piston rod and G3/4 ports to handle high flow requirements.
Configured with a SUS304 stainless steel rod (option B) and PT tapered ports, this extruded aluminum barrel cylinder omits the FB, CA, CB, and CR mounts, utilizing a focused mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a mechanical stop to fine-tune the retraction point during commissioning; it does not lock the load without live air pressure. For position holding without compressed air, an external rod lock or a related SAIL pneumatic lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-30 Is Used
Large Press Feeders
Dial in the exact 920-950 mm material push length during machine setup, allowing rapid accommodation of different blank sizes without changing the cylinder.
Heavy Assembly Stations
Provides the 14074 N push force needed to seat large components, while the rear stopper allows operators to fine-tune the final clamping position.
Pallet Positioning
Adjusts the retraction end-stop on the fly to handle varying pallet depths on a packaging line, ensuring precise alignment without external hard stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-30 the Right Cylinder?
Selecting this 160 mm bore cylinder makes sense when your application requires the 10053 N pull force at 0.5 MPa and a variable end-stop, avoiding the need to physically swap cylinders during product changeovers. If your setup only requires 6136 N of push force at 0.5 MPa, stepping down to a 125 mm bore saves space and air consumption, whereas moving up to a 200 mm bore yields 15708 N of push force for heavier loads. Because this unit features a 950 mm stroke, the long unsupported piston rod is susceptible to side-loading; always use an external guide rail to prevent premature seal wear, even with the sturdy 40 mm rod diameter.
An adjustable stroke is chosen over a fixed SAI cylinder when you need on-the-fly end-position tuning without bolting on external stopper blocks. To match this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 950 mm stroke, 30 mm adjustment range, PT port threads, SUS304 rod material, and the specific mounting accessory. Note that without the -S magnet option, this unit cannot host CMSE reed or DMSE electronic sensors for position detection.

- ✓ 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 SAIJ160BX950-30 FAQ
Operating at 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it achieves a maximum push force of 18095 N.
The rear mechanical adjuster lets you shorten the 950 mm nominal stroke by up to 30 mm, creating a 920-950 mm travel window. This stopper fine-tunes the end position during commissioning but does not hold the load without live air pressure.
