Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-50S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X160-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm bore and 160mm stroke, G3/8 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-50S
The hard-anodized aluminum barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds the chamber efficiently, while the integrated magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves.
The -50 code means an external adjuster can shorten the extend stroke by up to 50 mm on-site, giving a usable range of 110-160 mm without swapping the cylinder. Nominal stroke remains the maximum, and the retract end stays fixed. Note that the adjustable stop only sets the end position; it does not lock the load. If you need to hold a load against air loss, add an external rod lock or a pilot-operated check valve, as the air cushion only decelerates the piston near the end of travel.

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-50S Is Used
End-Position Trimming
Fine-tune the extend reach by up to 50 mm on-site to dial in exact clamping depth without machining new spacers.
Variable Transfer Push
Adjust the push-off distance on the fly to handle different carton widths moving down the packaging line.
Shared Spare Inventory
Keep one cylinder in stock and set the stop screw to cover any extend length between 110 and 160 mm.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-50S the Right Cylinder?
When sizing this unit, stepping down to a 50 mm bore drops the 0.5 MPa push force to 982 N, while stepping up to an 80 mm bore raises it to 2513 N. The adjustable stroke is ideal when you need to fine-tune the extend end position on the machine or want a single spare cylinder that covers multiple stroke variants within that 110-160 mm window. You can mount it using basic, FA, LB, TC, TCM1, or TCM2 brackets. Because this model includes the -S magnet, it is ready for CMSE/DMSE switches. For any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to the piston rod.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ 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 Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X160-50S FAQ
At 0.5 MPa it pushes 1559 N and pulls 1402 N. At 0.7 MPa it pushes 2182 N and pulls 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The G3/8 air port feeds the 20 mm piston rod.
The external adjuster lets you shorten the extend stroke by up to 50 mm on-site. The nominal 160 mm stroke is the maximum, so the usable extend range is 110-160 mm. The retract end is fixed, and the stop sets position only.
