About the Airtac SCJ100 Standard Cylinder SCJ100X58-50
The SCJ100X58-50 is a double-acting, single-rod tie-rod cylinder that puts 3927 N of push force at your command at 0.5 MPa, rising to 7068 N at the maximum operating pressure of 0.9 MPa. Its defining feature is the rear-cap adjusting screw, which lets you shorten the stroke end by up to 50 mm in the field, making it invaluable for commissioning fine-tuning or adapting to wear without swapping the cylinder.
With a 25 mm diameter piston rod and a PT1/2 port, this 100 mm bore actuator includes an adjustable air cushion (29 mm long) for smooth deceleration. The body length A(SCJ) is 245 mm, and it handles speeds from 30 to 800 mm/s. The standard TPU seals and PT threads suit general industrial environments from -20 to +70 °C.
Airtac SCJ100 Standard Cylinder SCJ100X58-50 Technical Specifications
| Model | Airtac SCJ100 Standard Cylinder SCJ100X58-50 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø100 mm |
| Nominal stroke | 58 mm |
| Stroke adjustment | Up to 50 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 SCJ100X58-50 Is Used
Commissioning & Setup
Fine-tune the end position of a material stop gate during initial machine setup. The 50 mm screw adjustment allows operators to dial in the exact stopping point for different product sizes without any mechanical disassembly.
Wear Compensation
Automatically compensate for tooling wear in a clamping or pressing station. As a stamping die or clamp pad wears down, the stroke can be incrementally extended via the rear screw to maintain consistent contact pressure and part quality.
Format Changeover
Quickly adapt a pusher or diverter on a conveyor line for a new box size. The adjustable stroke end eliminates the need to change the cylinder or add physical stops, reducing changeover time between production runs.
Is the Airtac SCJ100 Standard Cylinder SCJ100X58-50 the Right Cylinder?
Step up to this 100 mm bore if a 63 mm cylinder's 1559 N push at 0.5 MPa is insufficient for your load; if you need less force, the 80 mm bore provides 2513 N. The SCJ's 50 mm adjustment range is ideal when the final stroke length is uncertain at design time, unlike a fixed-stroke SC. For a direct replacement, match the 100 mm bore, 58 mm nominal stroke, 50 mm adjust range, PT port thread, and basic mounting. If your application involves a stroke of 58 mm or more with a significant side load, consider an external guide rail or a guided cylinder to protect the rod and bearing from bending moments.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-50)
- ✓ 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 SCJ100X58-50 FAQ
At 0.5 MPa, the push force is 3927 N and the pull force is 3681 N. At the maximum operating pressure of 0.9 MPa, the push force reaches 7068 N. The push force is greater than the pull force because this is a single-rod cylinder.
A rear-cap screw lets you shorten the stroke end by up to 50 mm, providing field adjustability. Choose this SCJ when you need to fine-tune the piston's end position after installation, such as for commissioning, format changes, or wear take-up. Pick a fixed-stroke SC if your stroke length is final and will never need adjustment.
