About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-40S
The AirTAC SAIJ160X950-40-S is a double-acting ISO 15552 profile cylinder engineered with a rear stroke adjuster, allowing you to dial back the 950mm nominal travel to a precise 910-950mm window during commissioning. Built with a SUS304 stainless steel rod and a PT tapered port, it delivers substantial thrust, pushing 18095N at 0.9 MPa. This profile barrel design integrates sensor grooves on both sides for straightforward position feedback.
Because the rear adjuster acts purely as a mechanical stop, it decelerates the piston end-position without adding external stops, but it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. The standard variable air cushions at both ends work alongside the adjuster to absorb kinetic energy across the 30-500 mm/s speed range.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-40S Is Used
Variable End-Stop Tuning
Dial in the exact 910 to 950mm travel window during machine commissioning to fine-tune end positions without physically modifying the cylinder mounting.
Product Size Changeover
Adjust the rear stopper on the fly to accommodate different product lengths on a production line, saving time compared to replacing fixed-stroke actuators.
Heavy Press Positioning
Leverage the 18095N push force at 0.9 MPa for heavy pressing operations while using the rear screw to precisely limit the final stroke distance.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-40S the Right Cylinder?
Select this 160mm bore when an application requires the 18095N push force at 0.9 MPa and a variable end-stop for product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. If the force is excessive, stepping down to a 125mm bore yields 11045N at 0.9 MPa. To match this exact ISO 15552 footprint, specify the 160mm bore, 950mm stroke, 40mm adjustment, PT ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet for CMSE or DMSE sensors.
At a 950mm stroke, the 40mm diameter SUS304 rod and M36x2 thread provide robust resistance to bending, but long unsupported strokes inherently demand an external guide to prevent side-load damage. Remember that the rear stopper only sets the travel end and is not a locking mechanism.
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 SAIJ160BX950-40S FAQ
This 160mm bore cylinder generates a push force of 14074N at 0.7 MPa and 18095N at 0.9 MPa. The pull force at 0.9 MPa is 9425N due to the rod area displacement.
The rear adjuster acts as a mechanical stop that lets you shorten the 950mm nominal stroke by up to 40mm, providing an effective 910-950mm travel window. It only sets the end position and does not lock the load without live air pressure.
