Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 160mm 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 JSIJ40X160-100
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend adjustability to compact automation. The external stop screw lets you shorten the extend stroke by up to 100 mm, yielding a usable 60-160 mm range while keeping the retract end fixed. You can fine-tune the end position without swapping the cylinder itself. The hard-anodized aluminum extruded barrel makes the body shorter and more compact than a same-bore ISO 15552 unit.
This double-acting single-rod actuator handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 margin. It uses a G1/4 port, a 16 mm rod with an M14x1.5 thread, and 20.5 mm adjustable air cushions at both ends. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor. The cushions only decelerate the piston near stroke end; the cylinder will not hold a load on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100 Is Used
Clamp Stroke Tuning
Dial in the exact clamping reach on machining fixtures by shortening the extend stroke from 160 mm down to 60 mm without changing the physical mount.
Transfer Stopper Adjust
Accommodate varying product sizes on a line by turning the external stop screw to set the precise 60-160 mm extend position for each batch.
Compact Divert Arm
Fit a shorter JIS profile body into tight conveyor gaps while retaining enough push force to deflect packages onto a branching lane.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100 the Right Cylinder?
When sizing, the 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 this 628 N unit is too small. The JSIJ mounting set includes Basic, FA, LB, TC, TCM1, and TCM2 options. The adjustable stroke is ideal for sharing a spare across stroke variants or dialing in end positions during commissioning. Because this is a no-magnet SKU, it cannot accept position sensors; order an -S variant if you need CMSE or DMSE switches. For any stroke of 300 mm or longer, always guide the load to prevent side-load wear on the rod seals.
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 JSIJ40X160-100 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. This 40 mm bore cylinder uses a G1/4 air port and features a 16 mm piston rod.
The nominal maximum stroke is 160 mm. The external adjuster lets you shorten the extend stroke on site by up to 100 mm, giving a usable extend range of 60-160 mm. The retract end remains fixed, and the adjuster sets the end position rather than locking the load.
