About the Airtac SCJ32 Standard Cylinder SCJ32X60-20
The SCJ32X60-20 is a double-acting, single-rod pneumatic cylinder with a rear adjusting screw that provides up to 20 mm of field-adjustable stroke-end control. At 0.5 MPa, it delivers 402 N of push force and 345 N on the pull stroke, suiting it for light clamping, sorting, and positioning tasks where the final stop point needs fine-tuning during commissioning.
This 32 mm bore model uses a 12 mm diameter piston rod with an M10x1.25 rod thread and a PT1/8 air port. The adjustable air cushion is 21 mm long, and the SCJ body length is 182 mm, which is slightly longer than a fixed-stroke SC of the same envelope. It operates from 0.15 to 1.0 MPa and handles speeds of 30-800 mm/s.
Airtac SCJ32 Standard Cylinder SCJ32X60-20 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X60-20 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 60 mm |
| Stroke adjustment | Up to 20 mm (rear adjusting screw) |
| Acting type | Double acting (single rod) |
| Port size | PT1/8 |
| Rod thread | M10×1.25 |
| 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, 21 mm |
| Max stroke | Up to 1000 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
| Max (@1.0 MPa) | 82 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 SCJ32 Standard Cylinder SCJ32X60-20 Is Used
Commissioning & Setup
Fine-tune the end-of-stroke position by up to 20 mm during machine commissioning, eliminating the need to shim or reposition the cylinder body.
Small-Part Ejectors
Adjust the push stroke precisely for ejecting small plastic or metal parts from a die or fixture, preventing part damage from over-travel.
Wear Compensation
Take up mechanical wear in linkages or tooling over time by advancing the stroke end with the rear screw, maintaining consistent clamping or contact force.
Is the Airtac SCJ32 Standard Cylinder SCJ32X60-20 the Right Cylinder?
Choose the SCJ32 when you need to dial in the stroke end without swapping cylinders—ideal for format changes on small packaging machines. If you need more force, the 40 mm bore SCJ40 provides 628 N of push at the same 0.5 MPa. For applications where the stroke is fixed and never adjusted, the standard SC32 is a simpler, lower-cost alternative. A direct replacement must match the 32 mm bore, 60 mm nominal stroke, 20 mm adjust range, PT port thread, and basic mounting style.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-20)
- ✓ 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 SCJ32 Standard Cylinder SCJ32X60-20 FAQ
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. The maximum push force at the 0.9 MPa operating limit is 724 N. The pull force is lower because the rod reduces the effective piston area on the return stroke.
A screw in the rear cap limits how far the piston can retract, shortening the stroke end by up to 20 mm. You turn the screw to set the exact stop position. It adjusts the stroke length, not the force or speed, and does not lock the piston in place when air pressure is removed.
