About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-50
The AirTAC SAIJ160X80-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the 80 mm nominal stroke by up to 50 mm. This yields a highly versatile 30 to 80 mm usable travel window, letting you fine-tune the retract end-position at commissioning without swapping out the unit. It delivers substantial thrust, pushing with 10053 N and pulling with 9425 N at 0.5 MPa.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this model uses PT tapered ports and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Unlike a locking cylinder, the rear adjuster acts strictly as a mechanical stop to set travel limits and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-50 Is Used
Machine Changeover
Rapidly adapt the retract distance from 30 to 80 mm during product family transitions without disassembling the line or changing the cylinder.
End-Stop Tuning
Precisely dial in the final resting position of heavy tooling at commissioning, absorbing mechanical tolerances via the rear adjustment screw.
Heavy Forming Press
Provide up to 10053 N of pushing force at 0.5 MPa for heavy-duty forming or pressing tasks where the exact stroke depth must be finely regulated.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-50 the Right Cylinder?
Choose this 160 mm bore when you need the 10053 N push force at 0.5 MPa that a 125 mm bore (6136 N) cannot provide, but a 200 mm bore (15708 N) would be excessive overkill. The 50 mm adjustment range is ideal for product-size changeovers on a line, allowing you to reposition the end-stop on the fly rather than machining new external stops. To replace an ISO 15552 cylinder, match the 160 mm bore, 80 mm stroke, PT G3/4 port, and the desired mounting option from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). For load-holding without continuous air, select an AirTAC SAIL or BSAI series cylinder instead of relying on the adjuster.
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 SAIJ160BX80-50 FAQ
At a 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. It can deliver up to 18095 N of push force at 0.9 MPa.
The rear adjuster screw lets you shorten the 80 mm nominal stroke by up to 50 mm, creating a usable travel window of 30 to 80 mm. The adjuster is a mechanical stop that sets the end position and does not lock or hold the load without live air.
