The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X200-100H 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 SCJ80X200-100H is an 80 mm bore, double-acting, single-rod pneumatic cylinder with a field-adjustable stroke end. A rear-cap adjusting screw lets you shorten the effective stroke by up to 100 mm without removing the cylinder, which is ideal for commissioning fine-tuning or accommodating wear on tooling. The 25 mm diameter rod and PT3/8 ports deliver a push force of 2513 N at 0.5 MPa (4523 N at 0.9 MPa), placing it in a high-force class for pressing, clamping, and heavy positioning tasks.
This model is built with Viton (FKM) seals, extending the operating temperature range to 0–150 °C for reliable performance in hot or chemically aggressive environments. The tie-rod construction and 28 mm air cushion at each end ensure durable, quiet deceleration. With a body length A of 239 mm and a standard PT port thread, it drops directly into existing SCJ setups requiring high-temperature sealing.

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.
In a heated laminating press, the 100 mm adjustment range allows operators to dial in the exact final pressing thickness without mechanical shims. The Viton seals handle the sustained 120°C environment safely.
On a pallet stop in a high-temperature wash line, the stroke can be gradually extended via the rear screw to compensate for wear on the rubber stop bumper, maintaining consistent pallet positioning.
For a filling machine handling multiple container heights, the 200 mm base stroke with 100 mm adjustability covers a wide range. Changeover is a simple screw adjustment, avoiding cylinder swaps and reducing downtime.
Step up to a 100 mm bore SCJ if your application needs more force, as the SCJ100 delivers 3927 N of push at 0.5 MPa. For applications that don't require stroke adjustment, a fixed-stroke SC80X200 cylinder offers the same force and mounting footprint without the rear adjuster. This SCJ80X200-100H is a direct replacement for any AirTAC SCJ80 cylinder with a 200 mm nominal stroke, 100 mm adjust range, PT ports, basic mount, and Viton seals. For this 200 mm stroke, ensure the rod is not subjected to high side loads; if lateral forces are present, add an external linear guide or switch to a guided cylinder to prevent rod bending and seal wear.
Adjustable-stroke checklist
The push force is 2513 N at 0.5 MPa and 4523 N at the maximum operating pressure of 0.9 MPa. The pull force on the retract stroke is lower, at 2268 N at 0.5 MPa, because the 25 mm rod reduces the effective piston area on that side.
Yes, if you need the adjustable stroke feature. The SCJ80X200-100H shares the same 80 mm bore, 25 mm rod, PT3/8 ports, and basic mounting dimensions as a fixed-stroke SC80. The body length A is slightly longer at 239 mm to accommodate the rear adjusting screw. Ensure your machine has clearance for the extra length and that the -H Viton seal option matches your temperature requirements.
