About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-10
The AirTAC SAIJ160X25-10 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact short-stroke positioning. It features a rear adjusting screw that allows you to dial back the nominal 25 mm travel, creating a precise 15-25 mm usable window without swapping out the physical actuator. Delivering a substantial 10053 N pull force at 0.5 MPa, this bore size handles immense loads within a compact footprint.
This specific configuration incorporates a SUS304 stainless steel rod (material code B) for superior corrosion resistance and includes PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides, though this unit is supplied without a magnet. As a profile cylinder, it is dimensionally interchangeable per ISO 15552 standards, utilizing a mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-10 Is Used
Heavy-Duty Pressing
Fine-tune the 15-25 mm travel window during machine commissioning to achieve the exact seating force required for pressing heavy bearings or components without over-travel.
Product Changeover
Quickly adjust the rear stopper to accommodate minor variations in workpiece heights on a production line, avoiding the need to physically swap out the actuator.
Short-Stroke Clamping
Leverage the 10053 N pull force to secure massive fixtures or weldments, using the 10 mm adjustment range to set the precise clamping depth.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX25-10 the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your mechanism demands extreme push power—up to 14074 N at 0.7 MPa—over a very short distance. If your setup requires slightly less force, stepping down to a 125 mm bore yields 5734 N of pull at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N of pull. The adjustable stroke is chosen over a fixed SAI model when you need to fine-tune the end position during commissioning or accommodate minor product size changes on the fly.
Because the 40 mm diameter rod and M36x2 thread provide excellent rigidity, side-load concerns are minimal even with abrupt movements. However, the rear adjuster functions strictly as a travel stop and relies on the variable air cushion for deceleration; it is not a locking mechanism. If your application requires true load-holding without live air pressure, you must integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI series cylinder. To match this exact unit, specify: 160 mm bore, 25 mm stroke, 10 mm adjustment, PT ports, SUS304 rod, and no magnet.
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 SAIJ160BX25-10 FAQ
Operating at 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At a maximum 1.0 MPa operating pressure, it can deliver up to 2050 kgf.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 25 mm nominal stroke by up to 10 mm. This creates a usable travel window of 15-25 mm, enabling precise end-position tuning without adding external stops.
