About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-30S
The AirTAC SAIJ160X280-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stopper. It provides a nominal 280 mm stroke that can be dialed back by up to 30 mm, giving you a precise 250-280 mm usable travel window for exact end-position tuning at commissioning. Delivering 14074 N of push force at 0.7 MPa, this bore size handles heavy industrial loads with ease.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts solely as a travel stop to set deceleration, so it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-30S Is Used
Heavy Press Tuning
Fine-tune the 250-280 mm travel window during machine setup to precisely set the pressing depth without altering the mechanical mounting.
Product Changeover
Quickly adjust the end-stop position on a packaging line to accommodate different product sizes, minimizing downtime between runs.
Material Handling
Leverage the 14074 N push force to move heavy pallets while dialing in the exact retraction point for varied load dimensions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-30S the Right Cylinder?
Select this 160 mm bore when a 100 mm bore yields insufficient force (5497 N push at 0.7 MPa) or a 200 mm bore is excessive (21991 N). The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product changeovers without swapping hardware. To replace an ISO 15552 cylinder, match the 280 mm stroke, 30 mm adjustment, PT G3/4 port, and -S magnet. Since the stroke is 280 mm, ensure external guides support the load to prevent excessive side-loading on the rod.
Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster and air cushions do not function as a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160BX280-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 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 acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm, creating a 250-280 mm travel window. It only sets the travel end and does not lock the load without live air pressure.
