About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-30
The AirTAC SAIJ160X50-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 30 mm of travel trimming. This configuration yields a usable stroke window of 20-50 mm, allowing exact end-position calibration without external stops. It delivers a robust 10053 N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks.
This unit is built with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It operates at speeds of 30-500 mm/s and utilizes adjustable air cushions at both ends to decelerate the massive moving load smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-30 Is Used
Heavy-Duty Positioning
Dial in the 20-50 mm travel window to precisely set heavy clamping or press end-stops during initial machine commissioning.
Product Changeover
Quickly adjust the retract distance on the fly when switching product sizes on a line, avoiding the need to physically swap cylinders.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod in humid or washdown manufacturing environments requiring robust 10053 N pull force.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-30 the Right Cylinder?
Choose this 160 mm bore when 125 mm falls short (offering 6136 N push at 0.5 MPa) but you want to avoid the massive 3204 kgf output of a 200 mm bore. The adjustable stroke is ideal for machine setups requiring precise variable end-stops during product changeovers, unlike a fixed-stroke SAI cylinder.
Remember that the rear adjuster functions strictly as a travel stop, not a load lock; the cylinder cannot hold position without live air. For true fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI clamp-lock series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ160BX50-30 FAQ
It provides 10053 N of pull force and 14074 N of push force at 0.5 MPa. The operational speed range is 30-500 mm/s.
The rear adjuster acts as an external stopper, allowing you to shorten the 50 mm nominal stroke by up to 30 mm, resulting in a 20-50 mm usable travel window.
