About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50
The AirTAC SAIJ160X950-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 900 to 950 mm, letting you dial back the 950 mm nominal stroke by up to 50 mm during commissioning. Belonging to a high-force class, it delivers 14074 N of push force at 0.7 MPa. This specific configuration includes a SUS304 stainless steel rod (option B) and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this unit is specified without a magnet for electronic or reed sensors.
The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping cylinders or adding external stops. It is not a locking device; the cylinder cannot hold a load without live air pressure. For applications requiring true load-holding, an external rod lock or a related AirTAC series like SAIL or BSAI is required. The 160 mm bore utilizes a 40 mm diameter rod with an M36x2 thread, providing substantial rigidity, but the 950 mm stroke length still necessitates an external guide to manage side loads.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50 Is Used
Heavy Press Tuning
Dial in the exact end-of-stroke position on large pressing equipment without disassembling the cylinder or adding external stopper blocks.
Product Changeover Stops
Adjust the retract stop distance up to 50 mm to accommodate different product lengths on a conveyor line during rapid changeovers.
Large Assembly Jigs
Set precise travel limits on massive assembly jigs where the 950 mm stroke provides extended reach but requires exact end-position calibration.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-50 the Right Cylinder?
Selecting this 160 mm bore cylinder is ideal when your application requires high thrust, such as 18095 N at 0.9 MPa, combined with precise end-position tuning. If you need less force, stepping down to a 100 mm bore yields 7068 N at 0.9 MPa. The adjustable stroke is chosen over a fixed SAI cylinder when machine setups require variable end stops or product changeovers without mechanical modifications. Because the stroke is 950 mm, an external guide is highly recommended to prevent excessive side-loading on the rod.
This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. It omits the FB, CA, CB, and CR mounts. To match this exact configuration, specify a 160 mm bore, 950 mm stroke, 50 mm adjustment, PT port threads, SUS304 (B) rod material, and no magnet. The standard speed range for this bore is 30-500 mm/s.

- ✓ 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 SAIJ160BX950-50 FAQ
At 0.5 MPa it provides 10053 N of push force, at 0.7 MPa it provides 14074 N, and at 0.9 MPa it provides 18095 N. The maximum force at 1.0 MPa is 2050 kgf.
The rear adjusting screw allows you to shorten the effective travel from the 950 mm nominal stroke down to a minimum of 900 mm. This creates a 900-950 mm adjustable window, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
