Airtac JSI Series Standard Cylinder JSI63X30H
The AirTAC Airtac JSI Series Standard Cylinder JSI63X30H is a genuine double acting JIS-standard air cylinder with a Ø63mm bore and 30mm stroke, G3/8 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 JSI63X30H
Delivering 1559 N of push force at 0.5 MPa, the AirTAC JSI63X30H is a double-acting JIS-standard profile cylinder built for tight machinery layouts. Its extruded hard-anodized aluminum barrel sheds external rods to stay shorter and more compact than an equivalent ISO 15552 unit, while a two-way piston seal retains grease for extended, low-friction service. The -H designation specifies a Viton (FKM) high-temperature seal, making it well-suited for environments where standard NBR would degrade.
Because this SKU lacks the -S magnet, it cannot host CMSE or DMSE position sensors. For sizing, plan for about 935 N of real work at 0.5 MPa, which translates to lifting roughly 79 kg vertically with a 2:1 safety margin. The G3/8 port and M18x1.5 rod thread handle the 30 mm travel efficiently, and the adjustable 29 mm air cushions at both ends soften end-of-stroke impact.

Where the Airtac JSI Series Standard Cylinder JSI63X30H Is Used
Injection Mold Clamping
Provides short 30 mm clamping strokes on hot injection molding cells, leveraging the Viton -H seal to withstand ambient radiant heat near the barrel.
High-Temp Diverting
Pushes lightweight packages on packaging lines adjacent to heat-shrink tunnels, where the FKM seal outlasts standard rubber compounds.
Short-Stroke Ejection
Ejects small aluminum castings from press dies, using the 1559 N push force to knock parts free without consuming valuable machine footprint.
Is the Airtac JSI Series Standard Cylinder JSI63X30H the Right Cylinder?
When sizing this 63 mm bore, dropping down to a JSI50 yields 982 N of push at 0.5 MPa, whereas stepping up to a JSI80 provides 2513 N. Choose this model when your load sits safely under the 935 N practical working threshold. For vertical loads, remember that a standard cylinder drifts if air pressure drops or the valve is centered; the air cushion only decelerates the piston near stroke end and will not act as a lock. Use an external rod lock or pilot-operated check valve if the load must be held. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, plus I, Y, F, or U rod knuckles.
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 JSI63X30H FAQ
At 0.5 MPa it provides 1559 N push and 1402 N pull. At 0.7 MPa it yields 2182 N push and 1962 N pull. The theoretical maximum is 318 kgf at 1.0 MPa. It uses a G3/8 air port and a 20 mm rod with an M18x1.5 thread.
No. This specific SKU lacks the -S magnet, so CMSE or DMSE switches cannot detect the piston. You must select the -S variant to use sensors in the side grooves. The -H suffix indicates a Viton high-temperature seal.
