The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X200-30TC 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, 200mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X200-30TC is an 80 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end, offering up to 30 mm of rear-screw adjustment on its 200 mm nominal stroke. It delivers 2513 N of push force at 0.5 MPa (4523 N at 0.9 MPa) and uses a 25 mm diameter piston rod with PT3/8 ports, making it a robust choice for applications where the stroke length must be fine-tuned during commissioning or changeover without swapping the actuator.
This model comes configured with a centre trunnion (TC) mount, supplied with the TCM1 bracket, which allows the cylinder to pivot and is ideal for swinging or articulating loads. The body length A(SCJ) is 239 mm, and the adjustable air cushion decelerates the piston smoothly at both ends. As a genuine AirTAC component, it is built for reliable service in filtered air systems up to 1.0 MPa.

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.

| 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.

Quickly adjust the end position of a pusher or stop by up to 30 mm when switching between product sizes on a packaging or assembly line, eliminating the need for mechanical shims.
The TC centre trunnion mount allows the cylinder to pivot, making it perfect for opening and closing gates or diverters on conveyors where the exact closing position needs periodic fine-tuning.
In clamping or pressing operations, the 30 mm adjustment screw can be used to compensate for tooling or pad wear over time, maintaining consistent clamp force without reprogramming a controller.
Choose the SCJ80 when your application needs the 2513 N push force at 0.5 MPa that an 80 mm bore provides. If your force requirement is lower, stepping down to the 63 mm bore (1559 N push at 0.5 MPa) can reduce size and air consumption. For higher force, the 100 mm bore offers 3927 N push at the same pressure. Because this is a 200 mm stroke, a fixed-stroke SC cylinder is a simpler alternative if you never need to alter the stroke length. For a direct replacement, match an SCJ cylinder with an 80 mm bore, 200 mm nominal stroke, a 30 mm adjustment range, PT3/8 ports, and a TC centre trunnion mount.
Adjustable-stroke checklist
At the standard operating pressure of 0.5 MPa, it generates 2513 N on the push stroke and 2268 N on the pull stroke. The maximum push force at 0.9 MPa is 4523 N. The pull force is lower due to the area of the 25 mm piston rod.
Yes, if you need the ability to fine-tune the stroke end. The SCJ80X200-30TC has the same 80 mm bore and 200 mm maximum stroke as a standard SC80X200, but adds a rear adjusting screw with a 30 mm range. You must also match the TC centre trunnion mount and PT3/8 port thread.
