About the Airtac SCJ80 Standard Cylinder SCJ80X100-75TC
The SCJ80X100-75TC is a double-acting, single-rod pneumatic cylinder with a 75 mm rear adjusting screw for fine-tuning the stroke end position on the machine. With an 80 mm bore, it delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it a strong workhorse for medium-to-heavy industrial tasks where the stroke length needs to be dialled in during commissioning or changeover.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket, which allows the cylinder body to pivot and absorb misalignment in swinging load applications. The 25 mm diameter piston rod and 28 mm air cushion provide robust, decelerated end-of-stroke performance. The body length A is 239 mm, and the PT3/8 ports supply the standard 0.15-1.0 MPa operating pressure range.
Airtac SCJ80 Standard Cylinder SCJ80X100-75TC Technical Specifications

|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø80 mm |
| Nominal stroke | 100 mm |
| Stroke adjustment | Up to 75 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
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.
Theoretical Output Force (Ø80mm)
| 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.

Where the Airtac SCJ80 Standard Cylinder SCJ80X100-75TC Is Used
Format Changeover Adjustment
Quickly adjust the retract end position for different product sizes on a packaging or palletising line without swapping the cylinder or adding external hard stops.
Diverter Gate Actuation
Actuate a diverter or sorting gate on a conveyor where the final closed position must be precisely set to align with different lane widths, using the 75 mm adjustment range.
Clamping with Variable Thickness
Power a clamp for workpieces of varying thickness. The rear adjusting screw lets operators set the exact clamp closure point, preventing over-travel and part damage.
Is the Airtac SCJ80 Standard Cylinder SCJ80X100-75TC the Right Cylinder?
Select the SCJ80X100-75TC when you need a 100 mm nominal stroke with up to 75 mm of field-adjustable retraction from the rear cap. If your force requirement is lower, stepping down to the 63 mm bore reduces push force to 1559 N at 0.5 MPa; for higher force, the 100 mm bore delivers 3927 N. The TC centre trunnion mount is ideal for applications where the cylinder must swing during its stroke.
If you do not require stroke adjustability, a fixed-stroke SC80X100 cylinder with the same mount is a simpler alternative. For a direct replacement, match an SCJ cylinder with an 80 mm bore, 100 mm nominal stroke, a -75 adjust range, PT3/8 ports, and the F-SC80TC trunnion mounting kit. For strokes of 100 mm, rod buckling is not a primary concern, but always align the rod with the load to prevent side-loading and premature seal wear.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-75)
- ✓ Required force at your working pressure
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear adjusting screw, then lock it before running.
- check Adjust end cushion screws for smooth stops.
- check Use SCJ mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCJ80 Standard Cylinder SCJ80X100-75TC FAQ
At the standard 0.5 MPa operating pressure, the push force is 2513 N and the pull force is 2268 N. The push force is higher because the rod reduces the effective piston area on the return side. At the maximum operating pressure of 1.0 MPa, the theoretical push force is 5026 N.
You can replace a fixed-stroke cylinder with the SCJ80X100-75TC if you have a 100 mm stroke application and need up to 75 mm of field-adjustable retraction. Ensure your mounting is compatible with the centre trunnion (TC) style and F-SC80TC bracket. The port thread is PT3/8. The adjustable screw only shortens the stroke end; it does not extend the cylinder beyond its nominal 100 mm stroke.
