About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-100S
The AirTAC SAIJ160X450-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 450 mm travel by up to 100 mm. This creates a usable end-position window of 350 to 450 mm, providing immense flexibility during machine commissioning or product changeovers without swapping hardware. Built to handle heavy loads, it generates 14074 N of push force and 9425 N of pull force at 0.7 MPa.
This specific SKU incorporates a SUS304 stainless steel rod for superior corrosion resistance and features an integrated magnet for position sensing. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid control is managed via PT tapered ports sized at G3/4, while variable air cushions at both ends manage deceleration across its 30-500 mm/s operating speed range.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-100S Is Used
Variable Product Forming
Dial in the exact 350-450 mm end-stop for heavy-duty forming presses that handle multiple material thicknesses, ensuring precise depth control without mechanical changeovers.
Heavy Load Diversion
Adjust the retract stroke on the fly for large pallet handling lines, accommodating different pallet lengths while moving loads with 14074 N of thrust at 0.7 MPa.
Machine Commissioning
Fine-tune the final end position during equipment setup to perfectly align tooling, utilizing the 100 mm adjustment range to compensate for mechanical tolerances.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-100S the Right Cylinder?
Select this 160 mm bore when an application requires substantial thrust that exceeds the 5497 N push force of a 100 mm cylinder, but does not necessitate stepping up to a 200 mm bore. The adjustable 350-450 mm travel window is ideal for lines processing variable product sizes, allowing operators to fine-tune the retract stop on the fly. Because the 450 mm stroke is relatively long, an external guide should be used to prevent excessive side-loading on the SUS304 rod, despite its robust 40 mm diameter and M36x2 thread.
When specifying a replacement, ensure you match the 160 mm bore, 450 mm nominal stroke, 100 mm adjustment range, G3/4 PT ports, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an AirTAC SAIL or BSAI cylinder.

- ✓ 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 SAIJ160BX450-100S FAQ
At a standard operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 450 mm nominal length down to 350 mm. This provides a 100 mm tuning window for exact end-positioning, though it functions as a stop and not a lock.
