About the AirTAC JSI63
The AirTAC JSI63 is a double-acting standard air cylinder with a 63 mm bore and a 20 mm piston rod. At 0.5 MPa it pushes 1559 N and pulls 1402 N; at 0.7 MPa that rises to 2182 N push and 1962 N pull. Force depends on bore and pressure only, so every stroke on this page gives the same output.
All JSI63 versions share 3/8" air ports, an M18×1.5 rod thread and 20.5 mm adjustable air cushions. The cylinder runs on filtered air between 0.15 and 1.0 MPa (proof 1.5 MPa), from -20 to +70 °C, at 30 to 800 mm/s. This page lists 30 stock order codes with strokes from 25 to 315 mm; the catalog maximum stroke is 1500 mm.

Theoretical output force (Ø63 mm)
| Pressure | Push | Pull |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | 1962 N |
Push = pressure × bore area; pull subtracts the Ø20 mm rod area. Usable force is lower because of friction and back-pressure.

Where the JSI63 Is Used
General automation
About 1559 N at 0.5 MPa covers most pushing, lifting and indexing tasks.
Clamping fixtures
Rigid mountings hold the cylinder for clamps and presses.
Doors, gates and levers
Pivoting covers and brackets drive mechanisms that swing.
Choosing the Right JSI63 Configuration
Start with the stroke. Pick the exact travel your machine needs; a longer stroke adds length, weight and air consumption without adding force. If your length is not listed, request a quote and we will confirm whether it can be built.
Then choose the mounting. Basic (no code) uses the cylinder's own mounting holes. This bore is stocked with LB foot, FA front flange, FB rear flange, TC center trunnion. Foot and flange mountings hold the cylinder rigid for straight-line loads; clevis and trunnion mountings let it pivot when the load moves in an arc.
Finally pick the version: S adds a magnet for position sensors.
AirTAC JSI63 FAQ
No. Every JSI63 gives about 1559 N push and 1402 N pull at 0.5 MPa, whatever the stroke.
3/8" ports, PT thread as standard.
Brackets: LB foot, FA front flange, FB rear flange, TC center trunnion. Pick a pivoting cover or bracket when the load moves in an arc, a rigid one for straight-line loads.
Usually yes. Request a quote with the stroke, mounting and version and we will confirm whether it can be built, plus price and lead time.
0.15 to 1.0 MPa operating pressure (proof 1.5 MPa) and -20 to +70 °C on filtered air.
No. You can order a single JSI63. Orders are processed and handed to the carrier within 3-5 business days.
