Airtac JSI Series Standard Cylinder JSI32X40S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X40S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 40mm stroke, G1/8 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 JSI Series Standard Cylinder JSI32X40S
Delivering 402 N of push force at 0.5 MPa, this 32 mm bore double-acting actuator fits tight machinery layouts by being shorter and more compact than an ISO 15552 cylinder of the same size. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed or electronic switches directly into the side grooves for position sensing. Operating on a G1/8 port with a 12 mm rod and M10x1.25 thread, it handles speeds of 30-800 mm/s.
For practical sizing, plan for about 241 N of real work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The adjustable air cushions at both ends decelerate the piston smoothly near the stroke limits, but remember they are not a locking device; if air is lost, the rod drifts, so use an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSI Series Standard Cylinder JSI32X40S Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of a press using 402 N of force at 0.5 MPa, with the -S magnet confirming retraction.
Electronic Assembly Pick-Place
Moves delicate PCB components vertically, safely lifting about 20 kg with a 2:1 margin in compact assembly cells.
Package Diverting
Actuates a routing gate on a 30-800 mm/s conveyor line where the shorter JIS profile saves valuable machine footprint.
Is the Airtac JSI Series Standard Cylinder JSI32X40S the Right Cylinder?
When sizing this 32 mm bore option, stepping up to the JSI40X40S provides 628 N of push force at 0.5 MPa for heavier demands, while 32 mm is the smallest available JSI bore, meaning you must look outside the series for lighter duties. The included -S magnet pairs perfectly with CMSE or DMSE sensors for end-of-stroke confirmation. Since the 40 mm stroke is relatively short, side-load and rod-bending stresses are minimal, but always ensure the mounting method—whether an LB foot, FA/FB flange, or an I/Y/F/U rod knuckle—aligns the load precisely to prevent premature seal wear.
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 JSI Series Standard Cylinder JSI32X40S FAQ
This 32 mm bore cylinder features a G1/8 air port and delivers a push force of 402 N and pull of 345 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving space on tight machines. It uses an extruded hard-anodized aluminum barrel with no external rods, and this -S variant includes a magnet for CMSE/DMSE sensors.
