About the Airtac SCJ32 Standard Cylinder SCJ32X275-10
The SCJ32X275-10 is a double-acting, single-rod pneumatic cylinder that provides a 10 mm field-adjustable stroke end via a rear-cap screw, letting you fine-tune the 275 mm nominal stroke without swapping the unit. Its 32 mm bore delivers 402 N of push force at 0.5 MPa, driven by a 12 mm diameter piston rod with M10x1.25 threads, and the PT1/8 ports keep plumbing compact.
Built on a proven tie-rod platform, this cylinder includes an adjustable air cushion (21 mm length) for smooth end-of-travel deceleration. The body length A is 182 mm, and the operating range spans 0.15 to 1.0 MPa with a speed of 30-800 mm/s, making it a precise, repeatable actuator for commissioning and format-change tasks.
Airtac SCJ32 Standard Cylinder SCJ32X275-10 Technical Specifications
| Model | Airtac SCJ32 Standard Cylinder SCJ32X275-10 |
|---|---|
| Series | SCJ adjustable-stroke tie-rod cylinder |
| Bore size | Ø32 mm |
| Nominal stroke | 275 mm |
| Stroke adjustment | Up to 10 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 SCJ32X275-10 Is Used
Commissioning Fine-Tuning
The 10 mm screw adjustment lets technicians dial in the exact end position during machine setup, compensating for stack-up tolerances without re-machining brackets.
Small-Part Diverting
Adjust the stroke end to match different lane widths on a packaging conveyor, using the 402 N push force to reliably divert lightweight cartons.
Wear Take-Up on Clamps
In a repetitive clamping fixture, the adjustable stroke compensates for pad wear over time, maintaining consistent grip force without replacing the cylinder.
Is the Airtac SCJ32 Standard Cylinder SCJ32X275-10 the Right Cylinder?
Choose the SCJ32X275-10 when you need to dial in a stroke end on a 275 mm throw without adding external hard stops. If your force requirement grows, the 40 mm bore SCJ delivers 628 N push at 0.5 MPa; for a lighter, fixed-stroke solution, the standard SC series removes the adjuster. A direct replacement must match the 32 mm bore, 275 mm nominal stroke, 10 mm adjust range, PT port thread, and basic mounting. For strokes of 300 mm or more, evaluate side-loading on the 12 mm rod and consider an external guide or a guided cylinder if the load is not perfectly axial.
Adjustable-stroke checklist
- ✓ Need to fine-tune stroke on the line?
- ✓ Nominal stroke + adjust range (-10)
- ✓ 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 SCJ32X275-10 FAQ
At 0.5 MPa, it generates 402 N pushing and 345 N pulling due to the single-rod design. At the maximum operating pressure of 1.0 MPa, the theoretical push force reaches 804 N.
A rear-cap screw limits the piston's forward travel by up to 10 mm, setting the stroke end. It does not lock the rod; if air pressure is lost, the piston can drift. For position holding without pressure, you need an external rod brake or pilot-operated check valve.
