About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-40S
The AirTAC SAIJ160X210-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 210 mm travel by up to 40 mm. This yields a precise 170-210 mm usable travel window, allowing you to fine-tune the retract end position at commissioning without swapping out the cylinder or adding external stops. It delivers formidable thrust, pushing with 18095 N and pulling with 9425 N at 0.9 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and carries a robust M36x2 rod thread to manage high side loads. It includes a magnet (-S) for position sensing with AirTAC CMSE reed or DMSE electronic switches, and utilizes PT tapered port threads. The extruded aluminum barrel retains standard ISO 15552 mounting dimensions, supporting Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-40S Is Used
Machine Changeover
Fine-tune the 170-210 mm retract position during product size transitions without physically replacing the cylinder or adding external mechanical stops.
Commissioning Calibration
Dial in the exact end-of-stroke stop during initial machine setup to absorb mechanical tolerances and achieve precise positioning quickly.
Heavy Forming Press
Leverage the 18095 N push force at 0.9 MPa for heavy-duty forming operations while retaining the flexibility to trim travel by up to 40 mm.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-40S the Right Cylinder?
Choose this 160 mm bore when 0.9 MPa thrust around 18095 N is required; if you need less force, stepping down to a 125 mm bore yields 11045 N push force, while a 200 mm bore provides 28274 N. The adjustable stroke is ideal for machine setup and product changeover, providing a variable end-stop that fixed-stroke SAI cylinders cannot match. Remember that the rear adjuster is a travel stop, not a lock; this plain SAIJ will not hold a load without live air. For load-holding without pressure, consider SAIL or BSAI cylinders. To replace an ISO 15552 cylinder, match the 160 mm bore, 210 mm stroke, 40 mm adjustment, PT port, and -S magnet. For strokes of 300 mm or more, an external guide is recommended to support the rod and prevent side-load wear.
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 SAIJ160BX210-40S FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095 N and a pull force of 9425 N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 210 mm nominal stroke by up to 40 mm, creating a 170-210 mm usable travel window. It only sets the end position and deceleration; it does not lock or hold the load without live air pressure.
