About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-100S
The AirTAC SAIJ160X250-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 150 to 250 mm for precise end-position tuning. Featuring a robust 160 mm bore, it delivers 9425 N of pull force at 0.5 MPa and up to 18095 N of push force at 0.9 MPa. The integrated -S magnet allows for direct mounting of CMSE reed and DMSE electronic solid-state sensors along the dual extruded barrel grooves.
This variant utilizes a SUS304 stainless steel rod (code B) for superior corrosion resistance and carries PT tapered port threads. The rear stopper functions strictly as a travel end-stop for commissioning adjustments, not a load-holding lock; position holding without live air requires a SAIL or BSAI variant. It supports the reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-100S Is Used
Heavy Machinery Setup
Fine-tune the 150 to 250 mm travel window during heavy equipment commissioning to achieve precise mechanical positioning without machining new hard stops.
Product Size Changeover
Adjust the rear stopper on the fly to accommodate different product lengths on a manufacturing line, reducing downtime between production runs.
High-Force Positioning
Leverage the 18095 N push force at 0.9 MPa for large material handling tasks while relying on the SUS304 rod for harsh environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX250-100S the Right Cylinder?
Select this 160 mm bore actuator when an application requires heavy thrust combined with variable end-stops, stepping up from a 125 mm bore that yields 5734 N pull at 0.5 MPa. The 100 mm adjustment range is ideal for product-size changeovers on a line, allowing you to dial back the 250 mm nominal stroke to 150 mm without swapping the cylinder or adding external stops. For true load-holding without continuous air pressure, integrate an external pilot-operated check valve or switch to a SAIL lock cylinder, as the SAIJ rear adjuster only sets the travel end.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 250 mm stroke, 100 mm adjustment, PT G3/4 ports, and the -S magnet requirement. Because the 250 mm stroke is substantial, the 40 mm rod diameter handles high side loads well, but an external guide is still recommended for unsupported loads to prevent premature seal wear. Operating speed ranges from 30 to 500 mm/s.
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 SAIJ160BX250-100S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster allows you to shorten the 250 mm nominal stroke by up to 100 mm, creating a usable travel window of 150 to 250 mm. It acts as a mechanical stop for end-position tuning and is not a lock.
