About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-10
The AirTAC SAIJ160X55-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. It features a SUS304 stainless steel rod and PT tapered ports. By integrating an external stopper at the rear, this model allows you to fine-tune the effective travel down from the 55mm nominal stroke, creating a precise 45-55mm usable window without swapping out the entire unit.
Because the adjustment mechanism acts purely as a mechanical stop, it cannot hold a load safely without continuous live air pressure. For true load-holding requirements, you would need to specify a SAIL or BSAI variant. This extruded aluminum barrel design includes sensor grooves on both sides, and operating speeds are rated for 30-500mm/s.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-10 Is Used
Heavy Press Tuning
Dial in the exact 45-55mm contact depth during heavy pressing operations to compensate for material thickness variations without remounting the actuator.
Product Changeovers
Quickly adjust the rear stopper on a packaging line to accommodate slightly different product sizes, reducing setup downtime between production runs.
Machine Commissioning
Fine-tune the end-of-stroke position during initial equipment commissioning to perfectly align heavy mechanical linkages on the fly.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX55-10 the Right Cylinder?
Choose this 160mm bore when an 80mm bore (providing 2513N push at 0.5 MPa) is insufficient, but a 200mm bore (15708N push) would be physically oversized for your machine. The adjustable stroke is ideal for machine setup and product changeovers, letting you dial in the exact end position on the fly rather than machining custom external stops or reverting to a fixed-stroke SAI cylinder. When matching ISO 15552 replacements, verify the 55mm stroke, 10mm adjuster, PT ports, SUS304 rod, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ160BX55-10 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 55mm nominal stroke by up to 10mm, providing a usable travel window of 45-55mm. It only sets the travel end and does not lock the load without live air.
