Airtac JSI Series Standard Cylinder JSI100X500
The AirTAC Airtac JSI Series Standard Cylinder JSI100X500 is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 500mm stroke, G1/2 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 JSI100X500
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X500 is a heavy-duty double-acting JIS-standard profile cylinder built for long 500 mm travels. Its extruded hard-anodized aluminum barrel omits external rods entirely, making the unit noticeably shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring low-friction operation over extended cycle life.
Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. For practical sizing, plan for about 2356 N of real work at 0.5 MPa, which safely lifts roughly 200 kg vertically with a 2:1 margin. The G1/2 air port and M26x1.5 rod thread handle the high flow and structural loads required for heavy actuation tasks.

Where the Airtac JSI Series Standard Cylinder JSI100X500 Is Used
Injection Mold Clamping
Provides the 3927 N push force needed to secure heavy injection mold halves across a 500 mm opening distance on large molding presses.
Pallet Diverting
Extends 500 mm to push heavy product pallets off a high-speed main conveyor line onto a secondary packaging spur.
Vertical Lift Gate
Actuates a 200 kg industrial safety gate on a warehouse loading dock, utilizing the full 500 mm stroke to clear the doorway for forklift access.
Is the Airtac JSI Series Standard Cylinder JSI100X500 the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI63 yields 1559 N of push at 0.5 MPa, while moving up to a JSI125 provides 6136 N. This JSI100X500 strikes a balance for medium-heavy machinery. Because this is a standard double-acting cylinder, it will drift if air pressure is lost or the valve is centered; the adjustable 33 mm air cushions only decelerate the piston near the end of stroke and do not function as a locking brake. To hold a suspended load safely, install an external rod lock or a pilot-operated check valve.
Furthermore, the 500 mm stroke exposes the 32 mm rod to bending forces under offset loads. To prevent premature seal wear and rod damage, guide the load externally and ensure the piston rod is not subjected to lateral stress during the full extension cycle.
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 JSI100X500 FAQ
The JSI100X500 delivers 3927 N push and 3574 N pull at 0.5 MPa, 5497 N push and 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. It features a G1/2 air port, an M26x1.5 rod thread, and operates at speeds of 30-800 mm/s.
As a JIS-standard profile cylinder, the JSI100X500 features an extruded aluminum barrel without external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. Note that this specific SKU lacks a magnet, so it cannot support CMSE or DMSE sensors without upgrading to an -S variant.
