Airtac JSI Series Standard Cylinder JSI50X600S
The AirTAC Airtac JSI Series Standard Cylinder JSI50X600S is a genuine double acting JIS-standard air cylinder with a Ø50mm bore and 600mm 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 JSI Series Standard Cylinder JSI50X600S
Delivering 982 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an ISO 15552 unit of the same 50 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for a long, low-friction service life. Because the SKU includes the -S suffix, a built-in piston magnet is present, allowing CMSE or DMSE electronic switches to drop directly into the side sensor grooves for position detection.
For practical sizing, plan for around 589 N of real work at 0.5 MPa, which translates to lifting about 50 kg vertically with a 2:1 safety margin. The unit features a G1/4 air port, an M18x1.5 rod-end thread, and adjustable air cushions at both ends to smooth out deceleration over the 600 mm travel.

Where the Airtac JSI Series Standard Cylinder JSI50X600S Is Used
Carton Diverting Gate
Extends a 600 mm routing flap on a packaging conveyor, using the 982 N push force at 0.5 MPa to positively redirect heavy cardboard cartons without bouncing.
Vertical Parts Elevator
Raises lightweight plastic totes 600 mm between warehouse tiers, safely lifting roughly 50 kg loads thanks to the built-in 2:1 safety margin calculation.
Sample Test Extraction
Pulls a testing fixture out of a temperature chamber, relying on the 825 N pull force at 0.5 MPa and the hard-anodized barrel to resist daily wear.
Is the Airtac JSI Series Standard Cylinder JSI50X600S the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm version drops the 0.5 MPa push force to 628 N, while moving up to a 63 mm bore increases it to 1559 N. This model includes the -S magnet, making it fully compatible with CMSE and DMSE sensors for automated feedback. Because the 600 mm stroke is quite long, carefully support the load with an external guide to prevent rod bending and excessive side loading. Note that a standard cylinder will drift if air pressure is lost or the valve is centered; the end cushions only decelerate the piston near stroke end and do not function as a locking brake, so add a pilot-operated check valve or external rod lock if you need to hold a suspended load.
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 JSI50X600S FAQ
The 50 mm bore provides a push force of 982 N and a pull force of 825 N at 0.5 MPa. At 0.7 MPa, push is 1374 N and pull is 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 air port and operates at speeds between 30 and 800 mm/s.
This JIS-standard profile cylinder is shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore, saving footprint on tight machines. Because this specific SKU has the -S suffix, it contains a piston magnet and readily accepts CMSE or DMSE switches in the side grooves for position detection.
