About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX95-50
The AirTAC SAIJ160X95-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 95 mm stroke by up to 50 mm for a precise 45-95 mm usable travel window. Built to handle heavy loads, it delivers 9425 N of pull force at 0.5 MPa and reaches a maximum of 10053 N push force at 1.0 MPa. This configuration features a SUS304 stainless steel rod and PT tapered ports.\n\nBecause the adjuster acts purely as a mechanical stop on the retract end, it fine-tunes end positions during commissioning without requiring external stops or cylinder swaps. It utilizes variable air cushions at both ends (50 mm cushion length) to manage deceleration, but it will not hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX95-50 Is Used
Machine Changeover
Dial in the 45-95 mm travel window during product size changes without physically swapping the cylinder or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end-stop during commissioning to perfect the seating of heavy 160 mm bore tooling without altering the fixed forward stroke.
Assembly Pressing
Set precise lower-end travel limits for heavy pressing operations, relying on the 10053 N peak force while letting the air cushion handle deceleration.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX95-50 the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or frequent product changeovers, avoiding the need to stock multiple fixed-stroke SAI cylinders. If your thrust requirements are lower, stepping down to a 125 mm bore yields 5734 N pull force at 0.5 MPa; conversely, moving up to a 200 mm bore provides 15080 N pull. To match this ISO 15552 footprint exactly, specify a 160 mm bore, 95 mm stroke, 50 mm adjustment, PT port thread, and the SUS304 (B) rod material. Since the stroke is under 300 mm, side-load stress is minimal, though long unsupported loads should still use an external guide.
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 SAIJ160BX95-50 FAQ
The rear adjuster acts as a retract stop that shortens the 95 mm nominal stroke by up to 50 mm, giving an effective 45-95 mm travel window. It sets the end position but does not lock or hold the load without live air pressure.
At 0.5 MPa, it provides 10053 N push force and 9425 N pull force. At the maximum operating pressure of 1.0 MPa, the push force reaches 18095 N.
