About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-75
The AirTAC SAIJ100X160-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a 160 mm nominal stroke and a 75 mm adjustment range, it provides a usable travel window of 85 to 160 mm, enabling precise variable end-stops during machine setup or product changeover without adding external stops. Built around an extruded aluminum barrel with sensor grooves on both sides, it delivers a robust 5497 N of push force at 0.7 MPa.
This model is equipped with a SUS304 stainless steel rod (material code B) for superior corrosion resistance and features a PT tapered port thread. The rear adjuster acts solely as a travel stop to set deceleration and end positions; it does not hold the load without live air. For load-holding applications without continuous pressure, consider the SAIL or BSAI series, or an external rod lock.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-75 Is Used
Product Changeover
Dial in the 85 to 160 mm travel window during line changeovers to accommodate varying product lengths without swapping hardware.
End-Position Tuning
Fine-tune the retract end-position at commissioning using the rear screw, avoiding the need to bolt on physical external stops.
High-Force Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or fixtures into an exact datum, relying on the stop for repeatable deceleration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX160-75 the Right Cylinder?
Choose this 100 mm bore when your application requires significant thrust, such as 5497 N push at 0.7 MPa, stepping up from a 63 mm bore that provides 2182 N. The 75 mm adjustment range is ideal for machinery requiring frequent product-size changeovers, allowing you to dial back the stroke from 160 mm down to 85 mm on the fly. Since this is a 160 mm stroke, evaluate the side-load conditions; while the 25 mm rod and M20x1.5 thread handle substantial loads, long unsupported strokes still require an external guide. When replacing an ISO 15552 cylinder, match the 100 mm bore, 160 mm stroke, PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ100 Adjustable Cylinder SAIJ100BX160-75 FAQ
At 0.7 MPa operating pressure, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. At the maximum 1.0 MPa, the push force reaches 7068 N.
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm from the 160 mm nominal length, creating an 85 to 160 mm usable travel window. It functions as a travel stop for end-position tuning, not as a lock to hold the load without air pressure.
