The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X60-30SN is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 30 mm range without swapping the cylinder. Ø80mm bore, 60mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X60-30SN is an 80 mm bore double-acting single-rod cylinder that delivers 2513 N of push force at 0.5 MPa, giving you the muscle for medium-duty clamping and positioning tasks. Its rear adjusting screw provides up to 30 mm of stroke-end fine-tuning, letting operators dial in the exact stop position during commissioning or format changes without swapping the cylinder.
This model includes a built-in magnet for direct mounting of CMSG/DMSG sensors and is fitted with NBR (nitrile) seals, making it a cost-effective choice for general industrial air service. The 25 mm diameter piston rod and 28 mm air cushion work together to absorb end-of-stroke impact, while the PT1/8 port supplies ample flow for the 30-800 mm/s speed range.

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.

Related types: SC (single rod, fixed stroke), SCD (double rod), SCT (multi-position). SCJ mounting: Basic, FA, LB, TC, TCM1. Seals: TPU standard / H = Viton / N = NBR. Thread: blank = PT, G = G thread.
The 30 mm adjustment range allows technicians to precisely dial in the stroke end position during machine commissioning, eliminating the need for shims or external hard stops when setting up new tooling.
On packaging or assembly lines, operators can quickly adjust the cylinder's end stop to accommodate different product sizes or formats, significantly reducing changeover time between batches.
In high-cycle clamping or pressing operations, the adjusting screw can be used to take up mechanical wear in the tooling or workpiece, maintaining consistent clamping force and position over the life of the fixture.
Choose the SCJ80 when your application needs around 2513 N of push force at standard plant pressure. If you require more force, stepping up to the 100 mm bore provides 3927 N, while the 63 mm bore offers 1559 N for lighter tasks. For fixed-stroke applications, the standard SC series is a simpler alternative; if side loads are a concern, consider adding an external guide rail.
This SCJ80X60-30SN is a direct replacement for any AirTAC SCJ adjustable-stroke cylinder of the same 80 mm bore, 60 mm nominal stroke, and 30 mm adjustment range, provided it uses PT ports, basic mounting, and a magnet sensor. Always match the bore, stroke, adjust range, and port thread to ensure identical mounting dimensions and pneumatic performance.
Adjustable-stroke checklist
At 0.5 MPa, the cylinder provides 2513 N of push force (extending) and 2268 N of pull force (retracting). The push force is higher because pressure acts on the full 80 mm bore area, while pull force is reduced by the 25 mm rod area. Maximum push force at 0.9 MPa is 4523 N.
A screw in the rear cap allows you to shorten the stroke end by up to 30 mm from the nominal 60 mm maximum. This sets a new mechanical stop for the piston, giving you a field-adjustable stroke length between 30 mm and 60 mm. It does not change the cylinder's force or speed.
