Airtac TCM Triple Axis Cylinder TCM20X125SH
The AirTAC TCM Triple Axis Cylinder TCM20X125SH is a genuine JIS-standard guided cylinder with a Ø20mm bore and 125mm 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 TCM20X125SH
The AirTAC TCM20X125SH is a JIS standard twin-rod guided cylinder that integrates a drive piston between two guide rods in a single body. Because the guide unit itself prevents rotation and carries side load, you can skip mounting an external linear rail. It is double-acting and uses a brass sliding bearing, generating 157 N of push at 0.5 MPa. The non-rotating accuracy is ±0.08°, keeping a gripper or blade square under off-centre loads. A 125 mm stroke suits medium-travel handling tasks.
This bearing shrugs off dust, grit, and hard knocks, offering roughly twice the horizontal impact resistance of a plain cylinder. It features a Viton (FKM) seal for wider temperature ranges and a Ø10 mm piston rod on 1/8" PT ports. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. The standard built-in magnet fits CS1 (reed) or DS1 (electronic) switches in any of the four sensor slots.

| 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 |

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max | 32 kgf | |
Force is set by the bore and piston rod (Ø10 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 TCM20X125SH Is Used
Pallet Stop Gate
Halting heavy pallets on a dusty transfer line is easy with 157 N of push at 0.5 MPa. The brass sliding bearing tolerates grit and hard knocks where a ball guide would jam.
Off-Centre Gripper Slide
Moving a gripper with an unbalanced load relies on the ±0.08° non-rotating tolerance. The twin guide rods carry the moment load without needing an external rail.
Weld Cell Clamp
Clamping parts in a dirty weld cell requires impact tolerance. The brass bearing survives spatter and side loads, delivering 220 N of thrust at 0.7 MPa.
Is the Airtac TCM Triple Axis Cylinder TCM20X125SH the Right Cylinder?
If 157 N of thrust at 0.5 MPa is too much, step down to the Ø16 bore which provides about 101 N. If you need more force, the Ø25 bore gives roughly 245 N. Choose the TCL series with its steel-ball linear bearing instead if your application demands low friction, extreme precision, or high vertical loads. To replicate this unit, specify bore 20, stroke 125, 1/8" PT ports, the standard S magnet, and FKM seals.
Remember that air pressure does not lock the rod if the valve is centred or supply drops; the piston will drift. Install an external rod lock or a pilot-operated check valve if your load must remain safely suspended. Stroke ends use a fixed TPU bumper, so there is no cushion screw to adjust.
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 TCM20X125SH FAQ
At 0.5 MPa it provides 157 N of push and 118 N of pull. At 0.7 MPa the push increases to 220 N. The theoretical maximum force is 32 kgf.
It resists rotation but does not hold a load if air pressure is lost; the rod will drift. For vertical fail-safe holding, add an external rod lock or pilot check valve. The TCL series is better for high vertical loads.
