The AirTAC Airtac SCJ200 Standard Cylinder SCJ200X175-100S is a genuine double-acting SINGLE-ROD air cylinder with a rear-cap ADJUSTING SCREW: the stroke end is field-adjustable within a 100 mm range without swapping the cylinder. Ø200mm bore, 175mm nominal stroke, PT3/4 ports and adjustable end cushioning.
The SCJ200X175-100S is a double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, offering a nominal 175 mm stroke that can be shortened by up to 100 mm via the rear-cap adjusting screw. This 200 mm bore actuator delivers a substantial 15708 N of push force at 0.5 MPa, making it a powerful solution for heavy-duty industrial tasks where the stroke length needs fine-tuning during commissioning or for different product runs.
A built-in magnet allows direct mounting of CMSG/DMSG/EMSG sensors for precise end-of-stroke detection, while the standard TPU seals and PT ports keep the unit ready for standard compressed air systems. The cylinder features a 40 mm diameter piston rod and a 33 mm air cushion to decelerate large inertial loads smoothly, with a body length of 342 mm for the SCJ configuration.

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 | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 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.
On packaging or palletizing machinery, the 100 mm adjustment range allows operators to quickly reset the stroke end for different box or pallet sizes without replacing the cylinder or adding external hard stops, minimizing downtime.
During the setup of a large laminating or stamping press, the adjustable stroke lets technicians fine-tune the platen's final position to achieve the correct pressure and depth, compensating for variations in tooling thickness.
In high-cycle clamping or riveting fixtures, the stroke end can be gradually extended via the adjusting screw to compensate for mechanical wear on the tooling or workpiece contact surfaces, maintaining consistent clamp force over the machine's life.
Choose this SCJ200 model when you need the high force output of a 200 mm bore—15708 N push at 0.5 MPa—and require the ability to dial in the stroke end position on the machine. If your application demands even greater force, consider stepping up to the 250 mm bore SCJ250, which provides 24544 N of push at the same pressure. For applications that do not require stroke adjustability, the fixed-stroke SC200 series offers a simpler, more cost-effective alternative. This model is a direct replacement for an existing AirTAC SCJ200 cylinder with a 175 mm nominal stroke, 100 mm adjustment range, PT ports, and a magnetic piston.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, this cylinder produces 15708 N of push force and 15080 N of pull force. The maximum push force at the 0.9 MPa operating limit is 28274 N. The pull force is lower because the 40 mm rod reduces the effective piston area on the return stroke.
Yes, it can replace a fixed-stroke SC200 if you need the added benefit of stroke adjustability and the mounting points are compatible. The SCJ200 body is slightly longer to accommodate the adjusting mechanism. Ensure your replacement matches the 175 mm nominal stroke, 100 mm adjustment range, PT port threads, and magnetic piston configuration.
