About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-50
The AirTAC SAIJ160X850-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 850 mm travel by up to 50 mm for a precise 800-850 mm usable window. Built with an extruded aluminum barrel, it delivers massive thrust up to 18095 N at 0.9 MPa, making it suitable for heavy-duty press and lift operations.
This configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and PT tapered port threads. The rear screw acts purely as a mechanical stop to fine-tune the retract position during commissioning; it does not lock the load, so a SAIL or BSAI variant is required if you need to hold position without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-50 Is Used
Heavy-Duty Press Tuning
Fine-tune the 800-850 mm retract stop during setup to perfectly crush or form materials without recalibrating the entire press frame.
Pallet Positioning
Adjust the end-stop on the fly to accommodate different pallet lengths on a heavy-duty transfer line without changing out cylinders.
Large Assembly Machines
Dial in the exact clamping depth for oversized components during commissioning, utilizing the 18095 N force safely and accurately.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX850-50 the Right Cylinder?
Choose this 160 mm bore when you need substantially more force than a 125 mm cylinder (which provides 11045 N push at 0.9 MPa) but want to avoid the extreme size and 3204 kgf output of a 200 mm unit. The adjustable 800-850 mm window is ideal for product changeovers, letting you shift the end-stop without physically swapping the cylinder or adding external stops. For a fixed end position, a standard SAI cylinder is simpler, but SAIJ excels where exact retract tuning is required.
Because the 850 mm stroke is long and unsupported, the 40 mm rod diameter requires an external guide to prevent excessive side-loading and premature seal wear. To match this cylinder exactly for an ISO 15552 replacement, specify: 160 mm bore, 850 mm stroke, 50 mm adjustment, PT G3/4 ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet. Operating speed is 30-500 mm/s.
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 SAIJ160AX850-50 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. It can achieve a maximum push force of 10053 N at 0.5 MPa.
The rear adjuster screw lets you mechanically shorten the 850 mm stroke by up to 50 mm, creating an 800-850 mm travel window. It functions as a hard stop for end-position tuning and is not a locking device.
