About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-10
The AirTAC SAIJ160X155-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 145 to 155 mm, allowing you to dial back the nominal 155 mm stroke by up to 10 mm during commissioning without adding external stops. The rod is constructed from SUS304 stainless steel, and the fluid port utilizes a PT tapered thread.
Because the rear adjuster acts purely as a mechanical stop, it does not hold the load without live air pressure. For position holding without continuous air, consider the SAIL or BSAI variants. This extruded aluminum profile cylinder includes variable air cushions at both ends (50 mm cushion length) and operates at speeds of 30-500 mm/s. The barrel features sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE electronic switches if a magnet is specified later.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-10 Is Used
Heavy Press Fit Tuning
Dial in the exact 145-155 mm end position for heavy press fits during initial commissioning without machining new stopper blocks.
Product Size Changeover
Quickly adjust the retract stop on a packaging line when introducing a new product size, saving changeover time.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX155-10 the Right Cylinder?
The adjustable stroke is ideal for applications requiring exact end-position tuning at machine setup or during product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. When replacing an ISO 15552 cylinder, match the 160 mm bore, 155 mm stroke, 10 mm adjustment, PT port, and your required mounting option from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
With a 40 mm rod diameter and M36x2 rod thread, this cylinder handles high side loads well. However, for any stroke of 300 mm or more, an external guide is recommended to prevent rod binding. If your process requires load holding without live air pressure, this standard adjuster will not act as a lock; you must integrate an external rod lock or pilot-operated check valve.
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 SAIJ160BX155-10 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 155 mm down to a minimum of 145 mm. This creates a 145-155 mm usable travel window for fine-tuning the end position without swapping the cylinder.
