About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-30
The AirTAC SAIJ160X200-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 170-200mm usable travel window. Delivering 14074N of push force at 0.7 MPa, this large-bore actuator handles heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, though this standard configuration ships without a magnet.
A defining feature is the external rear adjusting screw, which allows you to dial back the stroke by up to 30mm during commissioning without swapping the cylinder or adding external stops. The PT tapered port threads provide a tight pneumatic seal, while the robust 40mm carbon steel rod and M36x2 thread accommodate high side loads. The rear adjuster functions purely as a travel stop to set end positions, not as a lock.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-30 Is Used
Heavy Press Fine-Tuning
Dial in the exact 170-200mm travel window during assembly line commissioning to accommodate varying material thicknesses without replacing the actuator.
Product Changeover Setup
Quickly adjust the rear stopper by up to 30mm when switching machinery between different product sizes, reducing downtime and avoiding external stop hardware.
Large Fixture Positioning
Leverage the 14074N push force at 0.7 MPa to move heavy industrial fixtures into place, using the adjustable end-stop to set precise final positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-30 the Right Cylinder?
Select this 160mm bore when an application demands substantial thrust—such as 14074N at 0.7 MPa—but requires exact end-position tuning during product changeovers. If your process needs less force, stepping down to a 125mm bore yields 8590N at 0.7 MPa, whereas moving up to a 200mm bore provides 21991N. Choose the SAIJ adjustable-stroke design over a fixed SAI model when you need a variable end-stop to compensate for mechanical tolerances on the fly.
To match this ISO 15552 cylinder for a replacement, verify the 160mm bore, 200mm stroke, 30mm adjustment range, PT G3/4 port, and carbon steel rod. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 200mm, external guiding is recommended to manage side loads. Note that the rear adjuster and air cushions only decelerate the load; they do not hold position without live air. For load-holding, use an external rod lock or consider the SAIL or BSAI series.

- ✓ 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 SAIJ160X200-30 FAQ
