About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-30S
The AirTAC SAIJ160X160-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. With a 160 mm nominal stroke and a 30 mm adjustment range, it provides a usable travel window of 130 to 160 mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops. At 0.7 MPa, it generates 14074 N of push force and 9425 N of pull force.
This unit features a standard carbon steel piston rod and includes a magnet (-S) for position sensing with AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-500 mm/s and uses a G3/4 PT port. The rear adjuster acts strictly as a travel stop to set deceleration, not as a lock to hold the load without live air.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-30S Is Used
Heavy Machinery Changeover
Dial in the 130-160 mm travel window during product size changes on large presses, using the rear stopper to set new end positions mechanically without reprogramming motion controllers.
Press End-Position Tuning
Fine-tune the exact bottoming position of heavy stamping or forming tools at commissioning, absorbing setup tolerances directly via the cylinder's 30 mm adjustment screw.
Large Fixture Alignment
Securely position large automotive or structural fixtures by adjusting the retract stop, ensuring components mate perfectly before the clamping sequence begins.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-30S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 3518 N push at 0.5 MPa) lacks the power for heavy moving masses, but a 200 mm bore is physically excessive. The adjustable stroke is ideal for product changeovers on large equipment, letting operators dial in the exact 130-160 mm end-stop mechanically rather than reprogramming fixed SAI cylinder positions. For load-holding without continuous air pressure, integrate an external rod lock or pilot-operated check valve, as the SAIJ adjuster is not a brake.
To achieve a true ISO 15552 replacement match, verify the 160 mm bore, 160 mm stroke, 30 mm adjustment, G3/4 PT port, and the -S magnet requirement. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Although the 40 mm rod and M36x2 thread handle substantial side loads, an external guide is recommended for this 160 mm stroke to prevent binding.
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 SAIJ160X160-30S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can achieve a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 30 mm, creating a usable travel window of 130 to 160 mm. It sets the travel end and deceleration point but does not lock the load without live air pressure.
