About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-10
The AirTAC SAIJ160X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical adjuster that fine-tunes the retract end position. This specific SKU provides a usable travel window of 640 to 650 mm, enabling exact end-stop calibration during commissioning without adding external stops. It delivers robust thrust, generating 9425 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
Constructed with a SUS304 stainless steel rod (code B) and PT tapered ports, this extruded aluminum barrel design integrates sensor grooves on both sides. It supports a speed range of 30-500 mm/s and includes variable air cushions at both ends to decelerate the payload smoothly. The adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-10 Is Used
Heavy Press Tuning
Dial in the exact 640-650mm end-stop on large metal forming presses to accommodate varying material thicknesses without swapping cylinders.
Pallet Changeover
Adjust the retract distance on the fly during packaging line format changes to handle different pallet dimensions securely.
Large Assembly Fixtures
Fine-tune the clamping reach on heavy-duty automotive assembly fixtures, ensuring precise positioning despite payload variations.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX650-10 the Right Cylinder?
Choose this 160 mm bore when an application requires substantial force, such as the 9425 N pull at 0.5 MPa, which is a significant step up from the 125 mm bore's 5734 N. The 10 mm adjustable range is ideal for product changeovers on a line where exact end-positioning varies slightly. For fixed travel without a stopper screw, the standard SAI cylinder is sufficient. Because the 650 mm stroke is long, an external guide is recommended to manage side loads and prevent rod binding.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 650 mm nominal stroke, 10 mm adjustment, PT G3/4 ports, and the SUS304 rod material. Note that SAIJ supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. If the machine requires holding the load without continuous air, use an SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a lock.
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 SAIJ160BX650-10 FAQ
At 0.5 MPa operating pressure, it provides 10053 N push force and 9425 N pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10 mm. This creates a 640-650 mm usable travel window for fine-tuning the end position at commissioning.
