About the Airtac SCJ100 Standard Cylinder SCJ100X75-30TC
The AirTAC SCJ100X75-30TC is a double-acting, single-rod tie-rod cylinder engineered for applications requiring precise, field-adjustable stroke-end positioning. With a 100 mm bore and a 75 mm nominal stroke, its rear-cap adjusting screw provides a 30 mm retraction range, allowing operators to fine-tune the stroke end without replacing the cylinder. At 0.5 MPa, it delivers a substantial 3927 N push force and 3681 N pull force, making it a powerful choice for heavy-duty industrial tasks.
This model features a centre trunnion (TC) mount, supplied with the TCM1 bracket, ideal for pivoting applications. The 25 mm diameter piston rod and PT1/2 port ensure robust fluid flow, while the 29 mm air cushion provides smooth, adjustable deceleration. The body length A(SCJ) is 245 mm, and the standard PT threads offer reliable, leak-free connections.
Airtac SCJ100 Standard Cylinder SCJ100X75-30TC Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X75-30TC |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 75 mm |
| Stroke adjustment | Up to 30 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/2 |
| 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, 29 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 (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SCJ100 Standard Cylinder SCJ100X75-30TC Is Used
Format Changeovers
Quickly adjust the retracted position for packaging machines that handle different box sizes, using the 30 mm screw range to set a new end stop without mechanical modifications.
Pivoting Conveyor Gates
The TC centre trunnion mount allows the cylinder to swing, while the adjustable stroke fine-tunes the gate's closed position to prevent product jams on a sorting line.
Clamping & Pressing
Dial in the exact clamping depth for a glue press with the 3927 N push force, compensating for tooling wear over thousands of cycles.
Is the Airtac SCJ100 Standard Cylinder SCJ100X75-30TC the Right Cylinder?
Select the SCJ100X75-30TC when you need to commission a machine with a 100 mm bore and fine-tune the end position within a 30 mm window. If your force requirements are lower, stepping down to the 80 mm bore provides 2513 N of push force at 0.5 MPa. For applications needing a fixed, non-adjustable stroke, the standard SC series is a direct alternative. This cylinder is a direct replacement for another AirTAC SCJ100X75-30TC with a TC mount and PT ports. For strokes of 300 mm or greater, consider an external guide to manage side loads and prevent rod bending.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-30)
- ✓ 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 SCJ100 Standard Cylinder SCJ100X75-30TC FAQ
At the standard 0.5 MPa operating pressure, the cylinder provides a push force of 3927 N and a pull force of 3681 N. The maximum push force at 0.9 MPa is 7068 N.
A screw in the rear cap allows you to shorten the stroke end by up to 30 mm. The 75 mm nominal stroke is the maximum; the screw lets you reduce it for fine-tuning the piston's stopping point.
