Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 100mm 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 JSIJ100~125 Adjustable Cylinder JSIJ100X100-100S
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore JIS profile cylinder is built for heavy-duty positioning. The extruded hard-anodized aluminum body is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing power. A G1/2 port supplies the air, and the integrated -S magnet allows direct mounting of CMSE or DMSE sensors in the side grooves.
The -100 code means an external adjuster can shorten the extend stroke by up to 100 mm on-site, letting you fine-tune the end position from 0 to 100 mm without swapping the cylinder. It handles about 2356 N of real work safely, which translates to lifting roughly 200 kg vertically with a 2:1 margin. Note that the retract end remains fixed, and the adjustable cushion only decelerates the load; you will need an external rod lock or pilot-operated check valve to hold a suspended load.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100S Is Used
Press Fit Tuning
Use the 100 mm extend adjuster to dial in the exact seating depth of a bearing press on the factory floor without changing the cylinder height.
Vertical Load Lowering
Lower heavy 200 kg fixtures with a controlled stop, adjusting the final end position in fine increments to suit different product heights.
Multi-Part Diverter
Shift packages of varying sizes on a conveyor by tweaking the extend stroke from 0 to 100 mm on-site to match each product profile.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-100S the Right Cylinder?
When sizing this 100 mm bore unit, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, while stepping up to a 125 mm bore increases it to 6136 N. The 100 mm adjustable window is highly useful when you need on-site end-position tuning or want a single shared spare across multiple stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this unit includes the -S magnet, it is ready for CMSE/DMSE switches. For any stroke length of 300 mm or more, always use a guide rail to prevent side-load damage to the rod.
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 JSIJ100~125 Adjustable Cylinder JSIJ100X100-100S FAQ
This 100 mm bore cylinder uses a G1/2 port and a 32 mm rod. It generates 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.
The nominal 100 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extend range of 0 to 100 mm. The retract end is fixed, and this stop is for positioning only, not load holding.
