Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 175mm stroke, G1/4 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 JSIJ32~50 Adjustable Cylinder JSIJ40X175-100
Generating 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for applications demanding exact end-position control. The extruded hard-anodized aluminum body is noticeably shorter than an ISO 15552 cylinder of the same bore, saving valuable machine space. It uses a G1/4 air port and a 16 mm rod with an M14x1.5 thread.
An external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, giving a usable range of 75 to 175 mm while the retract end remains fixed. This means you can fine-tune the end position without physically swapping the cylinder. In practical terms it handles about 377 N of real work, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet and cannot accept CMSE/DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-100 Is Used
Adjustable Clamping Stop
Dial in the exact 75 to 175 mm extend position on a machining fixture to clamp varying part widths without changing hardware.
Transfer Lane Diverter
Fine-tune the extend stroke on-site to deflect packages of different sizes into specific sorting lanes on a packaging line.
Compact Stacking Pusher
Leverage the shorter JIS profile to fit a 40 mm bore pusher into tight conveyor gaps, adjusting the stroke to build varied pallet patterns.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-100 the Right Cylinder?
When sizing this unit, the neighboring 32 mm bore offers 402 N push at 0.5 MPa for lighter duties, while the 50 mm bore steps up to 982 N if your load increases. The 100 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or dialing in a precise end stop during commissioning. You can mount it using the FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 175 mm, ensure adequate guidance to prevent side-load wear on the rod. Remember that a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve if you need to hold a load securely.
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 JSIJ32~50 Adjustable Cylinder JSIJ40X175-100 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it delivers 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. This 40 mm bore unit features a G1/4 air port and a 20.5 mm adjustable air cushion at each end.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, yielding a usable extend range of 75 to 175 mm. The retract end is fixed. This mechanism only sets the end position and does not lock the load.
