Airtac TCM Triple Axis Cylinder TCM50X25-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM50X25-S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 25mm stroke on twin guide rods. Its integrated brass sliding bearing gives high radial-load and impact resistance — about double the horizontal impact tolerance of a plain cylinder, holding the tool square to ±0.05° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM50X25-S
The AirTAC TCM50X25-S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. A central drive piston runs between two guide rods in a single integrated body, eliminating the need for an external linear rail. Delivering 982 N of push force at 0.5 MPa, this double-acting unit is built for heavy radial loads and demanding industrial environments.
The brass sliding bearing shrugs off dust, grit, and hard knocks, offering about twice the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam. It holds a non-rotating accuracy of ±0.05°, keeping grippers or plates square under offset loads. Stroke termination relies on fixed rubber TPU bumpers at both ends, as there is no adjustable air cushion to tune. Plumbing is straightforward via 1/4" ports, and the standard built-in magnet supports CS1 reed or DS1 electronic sensors across four body slots.

|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |

Specifications follow the official AirTAC TCL/TCM series datasheet (JIS standard). Confirm against the product label before installation. Thread options: PT (blank) / G / NPT. Every TC model ships with a built-in magnet for sensor switches.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max | 200 kgf | |
Force is set by the bore and piston rod (Ø20 mm); the twin guide rods carry side load and torque, not thrust. Actual usable force is lower than theoretical due to friction and back-pressure.

Where the Airtac TCM Triple Axis Cylinder TCM50X25-S Is Used
Pallet Transfer Line Stop
Halts heavy pallets moving on a conveyor using 982 N of thrust. The brass sliding bearing survives constant impacting and dusty warehouse grit without jamming.
Foundry Sand Mould Press
Compresses sand moulds where dirty environments would destroy a ball bearing. The twin guide rods handle the heavy side load while maintaining ±0.05° torsional accuracy.
Off-Centre Gripper Slide
Actuates a heavy gripper on a machining cell. The integrated guide rods absorb the offset moment load, keeping the tooling square without needing a separate linear carriage.
Is the Airtac TCM Triple Axis Cylinder TCM50X25-S the Right Cylinder?
Choosing this 50 mm bore yields 982 N of thrust at 0.5 MPa. If your application requires less force, stepping down to the Ø32 bore provides 402 N; conversely, moving up to the Ø63 bore offers 1559 N to handle heavier payloads. For applications needing low-friction movement or high vertical precision rather than impact tolerance, the sister TCL series with its steel-ball linear bearing is the better choice.
To replace this unit, match the 50 mm bore, 25 mm stroke, 1/4" port size, and PT thread form, ensuring the built-in magnet (S) is included. Note that the guide prevents rotation but will not hold a load vertically if air pressure drops; adding an external rod lock or pilot-operated check valve ensures fail-safe positioning.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Side load / torque the guide must carry
- ✓ TCL (precision, low friction) vs TCM (impact, radial load)
- ✓ Stroke & mounting face (top / bottom / rear)
- ✓ Port/thread type (PT/NPT/G)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check The guide unit takes side load & torque — but do not exceed the max safe load/torque for your stroke.
- check Mount from the top, bottom (screw or T-slot) or rear face; use the precision locating holes.
- check Do not disassemble the fixing block or guide unit — factory-set precision.
- check Fit CS1 / DS1 magnetic switches in the four sensor slots as needed.
Airtac TCM Triple Axis Cylinder TCM50X25-S FAQ
At 0.5 MPa it generates 982 N of push and 825 N of pull. At 0.7 MPa the push increases to 1374 N. The theoretical maximum force is 200 kgf, operating within a 0.15-1.0 MPa pressure range.
No, there is no adjustable air cushion. Each end of the cylinder uses a fixed rubber TPU bumper to soften the impact. You must size the load and speed accordingly, as there is no cushion screw to tune.
