The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X500-10S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 10 mm range without swapping the cylinder. Ø80mm bore, 500mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X500-10S is an 80 mm bore, double-acting, single-rod pneumatic cylinder with a 500 mm nominal stroke and a 10 mm rear-end stroke adjustment range. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, driven by a 25 mm diameter piston rod. The built-in magnet allows for direct mounting of CMSG/DMSG/EMSG sensors for piston position feedback.
This adjustable-stroke design uses a rear-cap screw to fine-tune the stroke end position without removing the cylinder from the machine, making it ideal for commissioning and wear take-up. The cylinder body length A is 239 mm, and it features a PT3/8 port with an M20x1.5 rod thread. Its 28 mm air cushion decelerates the piston smoothly at the end of travel, protecting the end cap from impact.

Specifications follow the official AirTAC SCJ (adjustable-stroke) datasheet. The rear adjusting screw sets the stroke end position; force is the same as the equivalent single-rod SC bore. Confirm against the product label before installation. Thread options: PT (standard) / G.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
SCJ is single-rod, so force matches the equivalent SC bore: push uses the full bore area, pull subtracts the rod area. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

The 10 mm rear adjustment screw allows maintenance teams to dial in the exact stroke end position during commissioning or after mechanical wear, ensuring consistent part contact on long-stroke actuators.
With a 500 mm stroke and 2513 N of push force, this cylinder moves heavy components across conveyors. The adjustable stroke compensates for variations in pallet or workpiece positioning.
The built-in magnet enables CMSG/DMSG sensor mounting for mid-stroke or end-of-stroke confirmation. This is critical in automated pressing operations where the adjustable stroke fine-tunes the final pressing depth.
Select this 80 mm bore for applications needing around 2500 N of push force at standard plant pressure. If your force requirement is lower, the 63 mm bore SCJ series provides 1559 N of push force at 0.5 MPa. For higher forces, the 100 mm bore steps up to 3927 N. The 10 mm adjustment range is suited for fine end-stop calibration on a long 500 mm stroke. If no stroke adjustment is needed, the fixed-stroke SC80X500 is a simpler, more cost-effective alternative.
For a 500 mm stroke, always assess side-loading on the 25 mm rod. If the load is not guided externally, an external guide rail or a guided cylinder should be used to prevent rod bending and premature seal wear. This model replaces any AirTAC SCJ80X500-10S with a PT port, basic mounting, and a magnet-equipped barrel.
Adjustable-stroke checklist
At 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 5026 N. The pull force is lower due to the area of the 25 mm piston rod.
Yes, if your application does not require field adjustment of the stroke end position, the fixed-stroke SC80X500 is a direct dimensional match for the basic body. The SCJ80X500-10S is specifically chosen when you need to fine-tune the stroke end by up to 10 mm without adding external hard stops.
