About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-75S
The AirTAC SAIJ160X80-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 5-80 mm window without adding external stops. Built with a SUS304 stainless steel rod, it delivers a robust 14074 N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides to accept CMSE reed and DMSE electronic switches.
This adjustable-stroke variant utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-75S Is Used
Machine Changeover
Quickly modify the cylinder's extended end-stop to accommodate different product lengths on the same production line without swapping out the actuator.
Heavy-Duty Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy pallets or fixtures, using the 5-80 mm travel window to fine-tune the final resting position.
Commissioning Calibration
Dial in the exact retract position during initial machine setup, eliminating the need to fabricate and install custom external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-75S the Right Cylinder?
Choose this 160 mm bore when you need higher thrust than the 125 mm bore, which provides 8590 N push force at 0.7 MPa. The adjustable stroke is highly beneficial during commissioning or product changeovers, allowing you to dial in the exact end-of-stroke position on the fly rather than machining external stopper blocks. To match this exact replacement, specify a 160 mm bore, 80 mm stroke, 75 mm adjustment, PT tapered ports, and the -S magnet.
Because the stroke is 80 mm, side-load risks are minimal, but always ensure the M36x2 rod thread is properly aligned. The standard speed range for this bore is 30-500 mm/s. Remember that the rear screw stopper only trims the travel; it cannot function as a brake or lock in the event of air loss.
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 SAIJ160BX80-75S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore double-acting cylinder generates a push force of 14074 N and a pull force of 9425 N.
The rear adjuster screw lets you shorten the nominal 80 mm stroke by up to 75 mm, providing an adjustable usable travel window between 5 and 80 mm. It acts as a mechanical stop and does not lock the load without live air.
