Airtac TCM Triple Axis Cylinder TCM25X20SH
The AirTAC TCM Triple Axis Cylinder TCM25X20SH is a genuine JIS-standard guided cylinder with a Ø25mm bore and 20mm 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 ±0.08° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM25X20SH
The AirTAC TCM25X20SH is a JIS-standard twin-rod guided cylinder that integrates a drive piston between two guide rods in a single body. Because the brass sliding bearing unit prevents rotation and absorbs side loading, you can skip mounting an external linear rail. This double-acting actuator generates 245 N of thrust at 0.5 MPa and holds a non-rotating tolerance of ±0.08°, keeping a gripper or blade perfectly square under off-centre loads. The 20 mm stroke suits short clamping and positioning moves.
Built for dirty, knocking environments, the brass sleeve shrugs off grit, weld spatter and hard radial impacts where a steel-ball guide would jam or brinell. It features a Ø12 mm piston rod and 1/8" PT ports. This configuration includes Viton (FKM) seals for elevated temperature service, and the standard built-in magnet works with CS1 reed or DS1 electronic switches across four sensor slots. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion.

| 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 – 500 mm/s |
| Non-rotating tolerance | ±0.08° (retracted) |

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 189 N |
| 0.7 MPa | 344 N | — |
| Max | 50 kgf | |
Force is set by the bore and piston rod (Ø12 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 TCM25X20SH Is Used
Weld-Cell Part Clamp
Tolerates weld spatter and dust in robotic cells. The 245 N push at 0.5 MPa secures metal blanks, while the brass sliding bearing survives heavy radial knocks where a ball guide would fail.
Pallet Stop Gate
Halts moving pallets on a dusty transfer line. Twin guide rods absorb the side impact of stopping a load, and the ±0.08° anti-rotation tolerance keeps the stop blade square.
Off-Centre Gripper Slide
Drives a gripper that lifts asymmetric parts. The integrated guide carries the offset torque without an external rail, and the 1/8" ports deliver air efficiently for rapid 30-500 mm/s cycles.
Is the Airtac TCM Triple Axis Cylinder TCM25X20SH the Right Cylinder?
If you need slightly less force, step down to the Ø20 bore which provides roughly 157 N of push at 0.5 MPa. For heavier radial duty, step up to the Ø32 bore which yields about 402 N. Choose the sister TCL series with its steel-ball linear bearing instead if your application demands low-friction, high-precision vertical movement rather than impact resistance. To replace this unit, match the 25 mm bore, 20 mm stroke, 1/8" PT ports, and standard S magnet. Remember that this cylinder will not hold a load if air pressure drops; the guide resists rotation but not gravity, so fit an external rod lock for 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 TCM25X20SH FAQ
At 0.5 MPa it provides 245 N of push and 189 N of pull. At 0.7 MPa the push increases to 344 N, with a theoretical maximum of 50 kgf. The operational speed range is 30-500 mm/s.
No. Each end of the stroke lands on a fixed TPU rubber bumper to soften the stop. There is no air-cushion screw to adjust. The standard built-in magnet works with CS1 reed or DS1 electronic switches.
