The AirTAC Airtac SCJ80 Standard Cylinder SCJ80X130-100 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, 130mm nominal stroke, PT3/8 ports and adjustable end cushioning.
The SCJ80X130-100 is an 80 mm bore double-acting single-rod cylinder whose rear-cap screw lets you shorten the stroke end by up to 100 mm without changing the barrel. At 0.5 MPa it delivers 2513 N push and 2268 N pull, making it a practical choice for medium-force clamping and pressing stations where the stop position needs frequent fine-tuning.
This tie-rod cylinder uses a 25 mm rod, PT3/8 ports and an M20x1.5 rod thread, with a 28 mm air cushion at each end. The SCJ body length A is 239 mm, slightly longer than the fixed-stroke SC of the same bore. Operating pressure spans 0.15–1.0 MPa, and the maximum push at 0.9 MPa reaches 4523 N.

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.

The 100 mm adjuster lets operators dial in a new end-stop for different product sizes on a packaging or labelling line without swapping the cylinder or adding mechanical hard stops.
During machine commissioning, engineers can incrementally shorten the stroke to find the ideal actuator position, then lock the screw — no need to stock multiple fixed-stroke cylinders.
On a conveyor pusher or diverter, the adjustable stroke compensates for pad wear over time, maintaining consistent product placement without reprogramming the PLC or changing hard stops.
Step up to the 100 mm bore if your application needs more than 2513 N push at 0.5 MPa — the SCJ100 delivers 3927 N. If the stroke never needs field adjustment, the fixed-stroke SC80 is a simpler, lower-cost alternative. For a drop-in replacement, match the 80 mm bore, 130 mm nominal stroke, 100 mm adjust range, PT3/8 ports, basic mounting and no magnet.
At 130 mm stroke the rod is well supported inside the bearing, but if side loads are present, add an external guide rail or switch to a guided cylinder to protect the rod bearing and seal from premature wear.
Adjustable-stroke checklist
Push force is 2513 N at 0.5 MPa, 3518 N at 0.7 MPa, and 4523 N at 0.9 MPa. Pull force is lower because the 25 mm rod reduces the piston area on the return side: 2268 N at 0.5 MPa. The adjusting screw does not alter the force.
Yes, provided the mounting and port match. The SCJ80 body is slightly longer (A = 239 mm) to house the rear adjusting screw. The stroke-adjust range is 100 mm, so the SCJ80X130-100 can cover any fixed stroke between 30 and 130 mm. Ensure the screw does not interfere with rear-mounted accessories.
