Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30 is a genuine double acting, adjustable stroke 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 JSIJ32~50 Adjustable Cylinder JSIJ50X600-30
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach tasks. The extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit. It feeds via a G1/4 port and carries a 20 mm piston rod with an M18x1.5 thread.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable 570 to 600 mm forward travel while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, and it safely handles about 589 N of real work or roughly 50 kg lifted vertically. Note this SKU lacks a magnet and cannot take a sensor; the -S variant is needed for CMSE or DMSE switches.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30 Is Used
Extended Transfer Push
Pushes parts down a long conveyor line, using the 30 mm adjuster to dial in the exact push-off distance for different pallet sizes.
Vertical Material Lift
Raises a 50 kg payload in a storage rack, using the adjustable forward stop to set precise shelf heights without repositioning the mount.
Long-Reach Clamping
Extends 600 mm to clamp large workpieces in a machining fixture, fine-tuning the final clamp position on-site to avoid distorting the part.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30 the Right Cylinder?
When sizing this unit, a 40 mm bore gives 628 N push at 0.5 MPa, while a 63 mm bore jumps to 1559 N, so the 50 mm bore sits perfectly in the middle for medium loads. The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in a final end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 600 mm stroke is long, always use an external guide to prevent rod bending and side loads. Without a -S suffix, this cylinder cannot accept magnetic sensors.
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 JSIJ50X600-30 FAQ
This 50 mm bore cylinder pushes 982 N and pulls 825 N at 0.5 MPa. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 air port.
The nominal 600 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable forward travel of 570 to 600 mm. The retract end is fixed. This stop only sets the end position and does not lock the load.
