The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X200-100 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, 200mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The AirTAC SCJ80X200-100 is an 80 mm bore, double-acting single-rod cylinder with a rear-cap adjusting screw that provides up to 100 mm of field-adjustable stroke-end control. Operating on filtered air, this model delivers a substantial 2513 N of push force and 2268 N of pull force at 0.5 MPa, with a maximum push of 4523 N at 0.9 MPa, making it a powerful solution for mid-range industrial tasks.
This tie-rod cylinder features a 25 mm diameter piston rod, PT3/8 ports, and a 28 mm air cushion for smooth deceleration. The body length A(SCJ) is 239 mm, and the adjustable stroke allows operators to fine-tune the end position by up to 100 mm without swapping the unit, ideal for commissioning and format changes.

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.
Fine-tune the actuator end-stop during machine commissioning without fabricating new hard stops, saving hours of mechanical adjustment time on packaging lines.
Quickly adapt the stroke length for different product sizes on a conveyor diverter or sorting gate, minimizing downtime between production runs.
Periodically adjust the stroke end to compensate for tooling or pad wear in clamping and pressing fixtures, maintaining consistent process force and position.
Select the SCJ80X200-100 when you need to dial in a precise stroke end position on the fly. If 2513 N of push force at 0.5 MPa is insufficient, stepping up to the 100 mm bore provides 3927 N. For applications where the stroke is fixed and never needs adjustment, a standard SC80X200 is a simpler, cost-effective alternative. A direct replacement must match the 80 mm bore, 200 mm nominal stroke, 100 mm adjustable range, PT3/8 port thread, and basic mounting. For this 200 mm stroke, ensure the rod is not subjected to high side loads; if lateral forces are present, add an external guide rail to prevent rod bending and premature seal wear.
Adjustable-stroke checklist
At the standard 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. The maximum push force at 0.9 MPa is 4523 N. The rear adjusting screw changes only the stroke end position, not the cylinder's force output.
The SCJ80X200-100 has a rear-cap screw that lets you shorten the stroke end by up to 100 mm in the field. A fixed-stroke SC80X200 has a set, non-adjustable 200 mm stroke. Choose the SCJ when you need on-machine flexibility for setup or changeovers; choose the SC for a simpler, fixed-motion application.
