About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-50
The AirTAC SAIJ160X230-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 180 to 230 mm, allowing you to dial back the nominal 230 mm stroke by up to 50 mm during commissioning. Delivering a robust 14074 N of push force at 0.7 MPa, it handles heavy-duty motion control. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This specific configuration is built with a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a PT tapered port thread. The 40 mm rod diameter and M36x2 thread provide excellent rigidity, though long unsupported strokes still benefit from an external guide. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-50 Is Used
Heavy-Duty Pressing
Provides 14074 N of thrust at 0.7 MPa for pressing assemblies, with the 50 mm adjuster allowing precise tuning of the final press depth.
Machine Changeover
Dial in the 180-230 mm travel window during product size transitions to set new end-stops rapidly without changing the cylinder hardware.
Automated Forming
Handles substantial forming loads using a robust 40 mm SUS304 rod, while the PT tapered port ensures a reliable high-flow pneumatic connection.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-50 the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial thrust—stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, making the 160 mm size necessary for high-force tasks. An adjustable stroke is selected over a fixed SAI model when a machine requires variable end-stops or fine-tuning during product changeovers without physically swapping the cylinder or adding external stops.
For drop-in ISO 15552 interchangeability, match the 160 mm bore, 230 mm stroke, PT port thread, and 50 mm adjustment code. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the stroke is 230 mm, external guiding is recommended to manage side loads. If true load-holding without live air is required, consider the SAIL or BSAI series, as the rear adjuster here is a stop, not a lock.
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 SAIJ160BX230-50 FAQ
At 0.7 MPa operating pressure, the 160 mm bore generates 14074 N of push force and 9425 N of pull force. The maximum push force reaches 18095 N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 230 mm down to 180 mm. It acts as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
