About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-100
The AirTAC SAIJ160X375-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 275 to 375 mm without adding external stops. Built with a 40 mm SUS304 stainless steel rod and a PT G3/4 tapered port, it delivers a robust 14074 N of pull force at 0.7 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches.
Because the nominal 375 mm stroke exceeds typical compact dimensions, the 40 mm rod diameter helps manage side loads, though an external guide is still recommended for unsupported loads. The rear adjuster acts purely as a travel stop to dial in exact end-positions during commissioning or product changeover; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL air-released lock or BSAI clamp-lock variants.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-100 Is Used
Format Changeovers
Dial in the 275-375 mm travel window during product-size transitions without physically replacing the cylinder or bolting on external stops.
Machine Commissioning
Use the rear stopper screw to precisely tune the retract end-position, absorbing mechanical tolerances during initial line setup.
Heavy Load Positioning
Leverage the 14074 N pull force at 0.7 MPa to shift heavy assemblies, relying on an external guide for the 375 mm stroke.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX375-100 the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust up to 18095 N at 0.9 MPa; if your application requires less force, stepping down to a 125 mm bore yields 11045 N at 0.5 MPa. The 100 mm adjustment range is ideal for machinery requiring variable end-stops during format or product-size changes, eliminating the need to physically swap a fixed-stroke SAI cylinder. When matching an ISO 15552 replacement, verify the 375 mm stroke, 100 mm adjuster, PT G3/4 port, SUS304 rod, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2—omitting FB, CA, CB, CR).

- ✓ 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 SAIJ160BX375-100 FAQ
At 0.7 MPa it provides 14074 N of pull force and 18095 N at 0.9 MPa. The maximum push force is 21991 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 100 mm, creating a 275-375 mm usable window. It sets the end-position but does not lock or hold the load without live air.
