Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 800mm 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 JSIJ40X800-100
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built with an extruded hard-anodized aluminum barrel and is notably shorter than a same-bore ISO 15552 unit. It provides a generous 800 mm extend stroke, but an external stop screw lets you trim that forward travel on-site by up to 100 mm, giving a usable range of 700-800 mm without swapping the actuator. The retract end remains fixed, and the G1/4 port handles the air supply.
This compact design yields a safe working load of roughly 377 N, which equates to lifting about 32 kg vertically with a 2:1 safety margin. Because this specific SKU lacks a magnet, it cannot accept CMSE or DMSE sensors. Note that the adjustable air cushions only decelerate the piston near the ends; a plain cylinder will drift on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-100 Is Used
Long-Reach Pusher
Pushes cartons down a 750 mm lane, using the 100 mm adjuster to dial the exact stop position for varying box sizes.
Elevator Stroke Trim
Lifts a 30 kg platform fixture vertically, relying on the external adjuster to set the precise 720 mm raised height.
Divert Gate Actuator
Extends a routing flap on a sorting line, fine-tuning the extend end-point by 50 mm to accommodate new product widths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X800-100 the Right Cylinder?
When sizing, the adjacent 32 mm bore offers 402 N push at 0.5 MPa, while the 50 mm bore steps up to 982 N, so this 40 mm bore sits comfortably in the mid-range. The -100 mm adjustable window is highly useful for sharing a spare across stroke variants or fine-tuning the end position on-site. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. At an 800 mm stroke, you must support the load with external guides to prevent rod bending and manage side loads. This non-magnetic SKU cannot take a switch; specify the -S version if you require CMSE/DMSE sensing.
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 JSIJ40X800-100 FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. This 40 mm bore unit uses a G1/4 air port and features a 20.5 mm adjustable air cushion at each end.
The 800 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 700-800 mm. The retract end is fixed. This mechanism sets the end position and does not lock the load.
