About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-20S
The AirTAC SAIJ160X225-20-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 205-225 mm usable travel window, allowing you to dial back the 225 mm nominal stroke by up to 20 mm during commissioning without swapping the unit. Operating at 0.15-1.0 MPa, it delivers 14074 N of push force at 0.7 MPa and 18095 N at 0.9 MPa.
This specific SKU incorporates a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches. It reaches speeds of 30-500 mm/s and relies on variable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-20S Is Used
Press Stroke Tuning
Dial in the exact 205-225 mm end position during machine commissioning to accommodate varying material thicknesses without adding external stops.
Product Changeover
Quickly adjust the retract end-stop on a high-force assembly line when switching to a new product size, saving changeover time.
Position Verification
Leverage the integrated magnet with DMSE electronic sensors to confirm end-of-travel positions while tweaking the stroke via the rear screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX225-20S the Right Cylinder?
Choose this 160 mm bore cylinder when an application demands high thrust (10053 N push at just 0.5 MPa) alongside precise end-position tuning. If your setup requires less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, whereas moving up to a 200 mm bore provides 21991 N at 0.7 MPa. The adjustable stroke is ideal for variable end stops and product changeovers, providing finer control than a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 225 mm stroke, 20 mm adjustment range, PT G3/4 port, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select a SAIL or BSAI cylinder.
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 SAIJ160BX225-20S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw lets you shorten the 225 mm nominal stroke by up to 20 mm, creating a 205-225 mm usable travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
