About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-75
The AirTAC SAIJ100X190-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 190 mm travel back by up to 75 mm. This creates a usable 115-190 mm end-position window, allowing you to dial in the exact retract distance during commissioning without swapping the cylinder or adding external stops. It delivers a robust 5497 N push force at 0.7 MPa, matching the standard SAI thrust class.
This SKU is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches. It uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-75 Is Used
Variable End-Stop Positioning
Dial in the retract distance from 115 to 190 mm during machine commissioning to accommodate varying product sizes without changing the cylinder.
Product Line Changeover
Quickly adjust the effective stroke by up to 75 mm when switching the production line to a new item, reducing setup downtime.
High-Force Assembly Press
Leverage the 5497 N push force at 0.7 MPa for heavy-duty assembly tasks while fine-tuning the exact end-position to prevent overtravel.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX190-75 the Right Cylinder?
Choose this 100 mm bore when your application requires high thrust (5497 N at 0.7 MPa) and a variable retract end-stop. If you need less force, stepping down to an 80 mm bore yields 3518 N at 0.7 MPa. The adjustable stroke is ideal for product changeovers on a line where exact positioning varies. Note that the rear adjuster acts purely as a travel stop, not a lock; the cylinder will not hold a load without live air. For true load-holding, consider an external pilot-operated check valve or the SAIL/BSAI series. To replace an ISO 15552 cylinder, match the 100 mm bore, 190 mm stroke, 75 mm adjustment, G1/2 port, and required mounting bracket.
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 SAIJ100BX190-75 FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective travel from the nominal 190 mm down to 115 mm. This provides a 75 mm tuning window for precise end-position setup without replacing the cylinder.
