The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X200-100S 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. Ø80mm bore, 200mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X200-100S is an 80 mm bore double-acting single-rod cylinder with a field-adjustable stroke end, giving you up to 100 mm of fine-tuning range without swapping the unit. At 0.5 MPa it delivers 2513 N of push force and 2268 N on the pull stroke, making it a strong mid-range actuator for positioning tasks that need frequent tweaking.
A rear-cap adjusting screw lets you dial in the exact stroke end position, which is invaluable during commissioning, format changeovers, or when taking up mechanical wear. The built-in magnet (S suffix) allows CMSG/DMSG/EMSG sensors to clamp directly onto the tie-rod barrel for reliable end-of-stroke detection. This model uses a 25 mm diameter piston rod, PT3/8 ports, and an air cushion length of 28 mm for smooth deceleration.

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.
Technicians can precisely dial in the stroke end position on a new assembly line without depressurizing the system, speeding up the initial machine runoff.
On a packaging line, quickly adjust the pusher stroke to accommodate a different box size, minimizing downtime between production batches.
In a clamping or pressing fixture, the 100 mm adjustment range can be used to take up slack as tooling or contact surfaces wear over time, maintaining consistent force application.
Step up to the 100 mm bore SCJ if your application demands more force—the 100 mm model provides 3927 N of push at 0.5 MPa. For lighter, faster-moving loads, the 63 mm bore SCJ offers 1559 N of push and a more compact body. If your stroke never needs adjustment, a fixed-stroke SC80X200 cylinder is a simpler, more cost-effective alternative.
This SCJ80X200-100S is a direct replacement for any AirTAC SCJ adjustable cylinder of the same 80 mm bore, 200 mm nominal stroke, and 100 mm adjust range, provided the port thread (PT), magnet option (S), and basic mounting match. At a 200 mm stroke, rod buckling is not a primary concern for purely axial loads, but for any significant side force, add an external guide rail or consider a guided cylinder to protect the rod and bearing.
Adjustable-stroke checklist
At the standard 0.7 MPa operating pressure, the push force is 3518 N and the pull force is 3175 N. The maximum push force at 1.0 MPa is 5026 N. Because this is a single-rod cylinder, the push force is always greater than the pull force due to the rod area.
Yes, if your existing cylinder is an AirTAC SCJ with an 80 mm bore, 200 mm nominal stroke, 100 mm adjust range, PT ports, and a built-in magnet. The SCJ is a tie-rod design, so mounting dimensions and the rear adjusting screw location are identical for the same bore and stroke class.
