Airtac TCM Triple Axis Cylinder TCM12X20-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM12X20-S is a genuine JIS-standard guided cylinder with a Ø12mm 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 ±0.10° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM12X20-S
The AirTAC TCM12X20-S is a JIS-standard twin-rod guided cylinder with a brass sliding bearing, built for duties where a plain rod would deflect. Being double-acting, it generates 57 N of push and 42 N of pull at 0.5 MPa. The integrated twin guide rods eliminate the need to align a separate external linear rail, saving assembly time and spatial footprint.
This 12 mm bore unit runs on M5x0.8 ports and a Ø6 mm piston rod, delivering a non-rotating accuracy of ±0.1° to keep blades or small grippers square under offset loads. Stroke termination relies on fixed TPU rubber bumpers at both ends, meaning there is no adjustable air-cushion screw to tune. Because the standard S magnet is integrated, you can drop a CS1 reed or DS1 electronic switch into any of the four sensor grooves.

| 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 | ±0.10° (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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 57 N | 42 N |
| 0.7 MPa | 79 N | — |
| Max | 12 kgf | |
Force is set by the bore and piston rod (Ø6 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 TCM12X20-S Is Used
Small Part Gripper Slide
With 57 N of thrust at 0.5 MPa, it shifts small off-centre gripper loads while the brass sliding bearing absorbs side-load impacts without jamming.
Dusty Transfer Line Diverter
The brass bearing shrugs off airborne grit and coolant where a steel-ball guide would wear, maintaining the ±0.1° non-rotating tolerance for reliable flap positioning.
PCB Edge Guide Mechanism
Its twin guide rods keep a blade perfectly square during electronic board routing, using the Ø6 mm rod on M5x0.8 ports to fit tight machine envelopes.
Is the Airtac TCM Triple Axis Cylinder TCM12X20-S the Right Cylinder?
When sizing this 12 mm bore, consider stepping down to the Ø10 bore for lighter tasks (offering 39 N push at 0.5 MPa) or moving up to the Ø16 bore for heavier radial loads (providing 101 N push at 0.5 MPa). Choose the sister TCL series instead if your application demands a steel-ball linear bearing for high-precision, low-friction vertical motion. The TCM12X20-S uses PT thread as standard, includes the S magnet, and operates within the 0.15-1.0 MPa range. Remember that this guided cylinder resists rotation but does not resist gravity; if air pressure drops, the rod will drift, so fit an external rod lock for fail-safe holding.
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 TCM12X20-S FAQ
At 0.5 MPa it provides 57 N push and 42 N pull. At 0.7 MPa the push increases to 79 N. The theoretical maximum force is 12 kgf.
Both ends utilize fixed rubber TPU bumpers to soften the stop. There is no adjustable air cushion or cushion screw to set. The standard S magnet works with CS1 reed or DS1 electronic sensors.
