About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-30S
The AirTAC SAIJ160X85-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 85 mm travel by up to 30 mm. This creates a precise 55-85 mm usable window, enabling on-the-fly end-position tuning during commissioning without swapping out the unit or adding external stops. It delivers robust thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
Built with a SUS304 stainless steel rod (option B) and PT tapered ports, this model is tailored for demanding environments. The extruded aluminum barrel features sensor grooves on both sides, and because this SKU includes the -S magnet, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches for exact position feedback. The generous 50 mm cushion length at both ends ensures controlled deceleration for heavy loads moving within the 30-500 mm/s speed range.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-30S Is Used
Variable End-Stop Positioning
Dial in the exact 55 to 85 mm travel distance during machine commissioning to accommodate different product heights without changing cylinders.
Heavy-Duty Forming Press
Leverage the 18095 N push force at 0.9 MPa for high-load stamping or pressing tasks, using the rear adjuster to fine-tune the bottom dead center.
Automated Assembly Changeover
Quickly reset the retract position for new production runs on a line, using the 30 mm adjustment window to adapt the stroke to new fixture dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX85-30S the Right Cylinder?
Selecting this 160 mm bore makes sense when an application demands high force—stepping down to a 125 mm bore drops the 0.5 MPa pull force to 5734 N, whereas this model provides 10053 N. The adjustable stroke is ideal for product changeovers on a line where the exact end-of-stroke contact point varies slightly by part size. For any application requiring the load to be held mechanically without live air pressure, note that the rear adjuster acts only as a travel stop, not a lock; in such cases, an AirTAC SAIL or BSAI clamping cylinder is required.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 160 mm bore, 85 mm nominal stroke, 30 mm adjustment range, PT port thread, and the -S magnet specification. The mounting interface accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, deliberately omitting FB, CA, CB, and CR brackets. Furthermore, the 40 mm rod diameter and M36x2 thread provide high structural rigidity, though even with this robust rod, long unsupported strokes still necessitate an external guide to prevent side-loading damage.
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 SAIJ160BX85-30S FAQ
At 0.5 MPa it provides 10053 N of pull force and 14074 N of push force. If you increase the operating pressure to 0.9 MPa, the push force reaches 18095 N.
The rear adjuster screw lets you shorten the 85 mm nominal stroke by up to 30 mm, providing a usable travel window of 55 to 85 mm. It acts as a mechanical stop for end-position tuning and is not a lock.
