About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX195-40
The AirTAC SAIJ160X195-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. It provides a usable travel window of 155-195 mm, allowing you to dial back the 195 mm nominal stroke by up to 40 mm during commissioning without swapping the unit. Equipped with a robust 40 mm SUS304 stainless steel rod and a PT G3/4 port, it generates 10053 N of pull force at 0.5 MPa, making it suited to heavy-duty positioning.
This model omits the FB, CA, CB, and CR mounting styles, utilizing a reduced ISO 15552 interface set comprising Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts strictly as a travel stop to set deceleration alongside the 50 mm air cushion, not as a load-holding brake; maintaining position without live air requires a SAIL or BSAI variant. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|

| 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 SAIJ160BX195-40 Is Used
Heavy Fixture Positioning
Dial in the 155-195 mm travel window to precisely seat heavy machining fixtures, accommodating minor dimensional variations in clamping setups.
Product Size Changeover
Quickly retune the rear stopper by up to 40 mm when switching a packaging line to a different carton length, avoiding physical cylinder swaps.
Machine Setup Tuning
Fine-tune the end-of-stroke deceleration point during initial machine commissioning to prevent impact damage to heavy payloads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX195-40 the Right Cylinder?
Choose this 160 mm bore when the 125 mm class (5734 N pull at 0.5 MPa) is insufficient for moving heavy fixtures, or step down if the 100 mm bore (3681 N pull) provides enough force. The 40 mm adjustment range is ideal for production lines running mixed product sizes, allowing variable end-stops and rapid changeover without adding external mechanical stops. For fixed travel without the need for commissioning fine-tuning, a standard SAI cylinder is the simpler alternative.
Because the nominal stroke of 195 mm is below the 300 mm threshold, external side-load guides are less critical here than with longer strokes, though the substantial 40 mm SUS304 rod naturally handles greater side loads than smaller variants. To match this cylinder exactly, specify: 160 mm bore, 195 mm stroke, 40 mm adjustment, PT G3/4 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and SUS304 (B) rod material. Remember that the rear adjuster only halts travel; it will not hold a load safely without continuous air pressure.
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 SAIJ160BX195-40 FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 2050 kgf.
The rear adjuster screw lets you shorten the effective travel from the 195 mm nominal stroke down to a minimum of 155 mm. It acts as a mechanical stop to tune the end position during setup, but it is not a lock and will not hold the load without live air pressure.
