The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X180-100 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, 180mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X180-100 is an 80 mm bore double-acting, single-rod cylinder with a 180 mm nominal stroke and a 100 mm rear-end adjustable stroke range. This design lets you fine-tune the stroke end position on the fly, delivering 2513 N of push force at 0.5 MPa and up to 4523 N at 0.9 MPa. The 25 mm rod and PT3/8 ports handle substantial loads, while the 28 mm air cushion decelerates the piston smoothly.
With a body length A of 239 mm, this tie-rod cylinder is purpose-built for applications where the stroke must be dialed in precisely during setup or changeover. The 100 mm adjustment range provides exceptional flexibility for wear take-up or format changes without swapping the cylinder. It operates on 40 µm filtered air from 0.15 to 1.0 MPa and is rated for speeds of 30-800 mm/s.

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.
The 100 mm adjustment range allows engineers to precisely dial in the end-stop position during machine commissioning, eliminating the need for custom-length cylinders or external hard stops.
Quickly adapt to different product sizes on packaging or sorting lines by adjusting the stroke end. The 2513 N push force at 0.5 MPa handles pusher and diverter gates with ease.
In clamping or pressing fixtures, the adjustable stroke compensates for tooling or pad wear over time, maintaining consistent contact force without reprogramming the machine control system.
Choose the SCJ80X180-100 when you need a robust mid-bore cylinder with a long field-adjustable stroke range. If 2513 N of push force at 0.5 MPa is insufficient, stepping up to the 100 mm bore provides 3927 N. For lower force requirements, the 63 mm bore delivers 1559 N. This model is ideal when the exact stopping position must be tuned on the machine. If your application does not require stroke adjustment, the fixed-stroke SC80X180 is a simpler alternative.
For a direct replacement, match an AirTAC SCJ80 cylinder with an 80 mm bore, 180 mm nominal stroke, a 100 mm adjust range, PT3/8 ports, and basic mounting. At this 180 mm stroke, side-loading is generally not a primary concern for the 25 mm rod, but always ensure the load is guided externally if significant radial forces are present.
Adjustable-stroke checklist
At 0.5 MPa, the push force is 2513 N and the pull force is 2268 N. The maximum push force at the 0.9 MPa operating limit is 4523 N. Because it is a single-rod cylinder, the push force is greater than the pull force due to the rod area on the piston.
A rear-cap adjusting screw lets you shorten the stroke end by up to 100 mm from the 180 mm nominal maximum. Choose the SCJ when you need to fine-tune the stopping position during commissioning, for format changes, or to take up wear. Pick a fixed-stroke SC if the stroke length is permanently fixed and never needs field adjustment.
