Airtac JSID Double Rod Cylinder JSID50X80LB
The AirTAC Airtac JSID Double Rod Cylinder JSID50X80LB is a genuine double acting, double rod JIS-standard air cylinder with a Ø50mm bore and 80mm 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 JSID Double Rod Cylinder JSID50X80LB
Delivering 825 N of thrust in both directions at 0.5 MPa, the AirTAC JSID50X80LB uses a twin-rod layout to provide identical push and pull output. A single piston drives a 20 mm rod out of both covers, which creates a symmetric load path that resists torsional twist. This JIS profile build is noticeably shorter than an ISO 15552 cylinder of the same 50 mm bore, relying on an extruded hard-anodized aluminum barrel rather than external steel rods.
With an 80 mm stroke and a G1/4 port, the unit is good for about 495 N of real work, roughly 42 kg lifted vertically. It includes adjustable 20.5 mm air cushions at both ends to decelerate the load smoothly. This specific SKU lacks a magnet, so it cannot accept CMSE or DMSE position sensors without upgrading to the -S variant.

Where the Airtac JSID Double Rod Cylinder JSID50X80LB Is Used
Twin-Tool Synchronization
Drives two opposing forming heads simultaneously from a single piston, ensuring perfectly matched contact pressure on both sides of a workpiece.
Anti-Rotation Web Guide
Uses the dual rods exiting both covers to prevent torsional deflection, keeping a cutting blade or squeegee perfectly level across a 80 mm stroke.
Symmetric Transfer Pusher
Pushes a part forward while moving a return cam backward at the exact same speed and force, ideal for timing the feed on a compact packaging line.
Is the Airtac JSID Double Rod Cylinder JSID50X80LB the Right Cylinder?
When sizing this double-rod family, the neighboring 40 mm bore yields 528 N both ways, while the 63 mm bore provides 1402 N. The 50 mm bore sits comfortably in the middle at 825 N. Choose this twin-rod architecture when your mechanism requires anti-rotation guidance, needs to drive two tools simultaneously from one cylinder, or demands a sensor cam on the back end. The LB foot mounting accessory supplied with this model provides a stable base. Because the stroke is 80 mm, side-load guidance is minimal but always verify the load is axially aligned. Note that a plain cylinder drifts on air loss; the cushions only decelerate near the end caps, so add an external rod lock or pilot-operated check valve 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 JSID Double Rod Cylinder JSID50X80LB FAQ
Because the 20 mm rod passes through both covers, force is equal in both directions. It generates 825 N at 0.5 MPa and 1154 N at 0.7 MPa each way, with a theoretical maximum of 168 kgf at 1.0 MPa. The air port is G1/4.
It can vertically lift roughly 42 kg with a 2:1 safety margin at 0.5 MPa. However, a plain cylinder cannot hold a load without live air pressure, as the cushions only decelerate the piston near the stroke end. You must add an external rod lock or pilot-operated check valve to prevent drift.
