The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X150-100 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, 150mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X150-100 is an 80 mm bore, single-rod double-acting cylinder that gives you up to 100 mm of field-adjustable stroke-end reduction via the rear-cap screw. Its nominal 150 mm stroke can be shortened without changing the cylinder, making it ideal for commissioning trials and format changeovers. At 0.5 MPa it delivers 2513 N push and 2268 N pull, with a 25 mm piston rod and PT3/8 ports.
This tie-rod cylinder uses an adjustable air cushion (28 mm length) to decelerate the piston smoothly. The body length A(SCJ) is 239 mm, slightly longer than a fixed-stroke SC to house the adjusting mechanism. Operating pressure spans 0.15–1.0 MPa, and the speed range is 30–800 mm/s. The stroke-adjust screw sets the end position only—it is not a force or speed regulator.

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.
Dial in the exact stroke end position during machine commissioning without swapping cylinders. The 100 mm adjustment range lets you test multiple end positions quickly, cutting setup time on assembly jigs and clamping stations.
Adjust the stroke end to match different product sizes on packaging or sorting lines. The rear screw makes it easy to reset the stop position when switching between box heights or pallet dimensions.
Compensate for tooling wear or seal compression over time by advancing the stroke end slightly. This keeps the actuator working at the correct position without reprogramming the PLC or adding shims.
Choose the SCJ80X150-100 when you need to fine-tune the stroke end on the machine without adding external hard stops. If 2513 N push at 0.5 MPa is too light, step up to the 100 mm bore (3927 N push); if it is more force than you need, the 63 mm bore delivers 1559 N push and a smaller footprint. For a fixed, non-adjustable stroke, the standard SC80X150 is the direct alternative.
This model is a direct replacement for an existing AirTAC SCJ80X150-100 with PT ports and basic mounting. If your application requires a magnet for sensors, order SCJ80X150-100S; for a centre trunnion mount, specify SCJ80X150-100TC. At 150 mm nominal stroke, the rod is well supported, but if side loads are present, add an external guide rail or consider a guided cylinder.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N (the difference is due to the single 25 mm rod). At the maximum operating pressure of 1.0 MPa, theoretical push force reaches 5026 N. Always size for your working pressure and a suitable safety factor.
Yes, this is a genuine AirTAC SCJ80X150-100 with PT ports, basic mounting, and a 100 mm adjustable stroke range. It directly replaces any AirTAC SCJ of the same bore, nominal stroke, and adjustment range. If your old unit had a magnet or different mount, match those suffix codes (e.g., -S for magnet, -TC for trunnion) when ordering.
