About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-20S
The AirTAC SAIJ160X50-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 30 to 50 mm, allowing you to dial back the 50 mm nominal stroke by up to 20 mm during commissioning. Belonging to a high-thrust class, it generates 10053 N of pull force at 0.5 MPa and reaches a maximum of 2050 kgf at 1.0 MPa. This variant includes a SUS304 stainless steel rod and a built-in magnet for position sensing.
The rear adjustment screw acts purely as a mechanical stop to fine-tune the end position without adding external stops. It does not hold the load without live air pressure. For load-holding without continuous air, consider the SAIL or BSAI series. This extruded aluminum profile cylinder uses PT tapered ports and operates at speeds of 30-500 mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-20S Is Used
Short-Stroke Pressing
Provides high-force pressing and clamping over a 30-50 mm adjustable window to accommodate varying material thicknesses.
Machine Changeover
Allows operators to fine-tune the retract end position on the fly during product line changeovers without swapping cylinders.
Heavy Assembly Stations
Delivers robust thrust for heavy-duty assembly stations while using the rear stopper to set exact positioning depths.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX50-20S the Right Cylinder?
Select this 160 mm bore model when an application demands substantial force within a very short, variable travel window. If the 10053 N pull force at 0.5 MPa exceeds your requirement, stepping down to the 125 mm bore yields 5734 N of pull force. Choose the adjustable SAIJ over a fixed-stroke SAI when you need precise end-position tuning during machine changeover or product-size adjustments. The SAIJ160X50-20-S is dimensionally interchangeable per ISO 15552 and includes a -S magnet for CMSE reed and DMSE electronic sensors. 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 SAIJ160BX50-20S FAQ
At 0.5 MPa it provides 10053 N of pull force and 14074 N of push force at 0.7 MPa. The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster lets you shorten the 50 mm nominal stroke by up to 20 mm, creating a 30-50 mm usable travel window. The adjuster is a mechanical stop, not a lock, and requires live air to hold the load.
