Airtac TCM Triple Axis Cylinder TCM12X125-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM12X125-S is a genuine JIS-standard guided cylinder with a Ø12mm 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 ±0.10° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM12X125-S
The AirTAC TCM12X125-S is a JIS-standard twin-rod guided cylinder featuring a brass sliding bearing. A central Ø6 mm piston drives between two integrated guide rods, generating 57 N of push at 0.5 MPa. Because the guide unit prevents rotation within a tight ±0.1° tolerance, it keeps a gripper or blade square under off-centre loads without needing an external linear rail. This 125 mm stroke suits compact transfer and indexing mechanisms.
Built for harsh duty, the brass sliding bearing shrugs off dust, grit, and hard knocks, delivering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam. Stroke termination relies on fixed TPU rubber bumpers at both ends, meaning there is no adjustable air cushion to tune. The standard built-in magnet works with CS1 reed or DS1 electronic switches across four sensor slots, and the M5x0.8 PT ports offer flexible plumbing from either the upper or side face.

| Acting type | Double acting |
| Bearing | Brass sliding bearing |
| Port size | M5×0.8 |
| 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) |
| Cushion | Rubber bumper |

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 TCM12X125-S Is Used
Dusty Transfer Line Diverter
Flipping a small gate on a gritty conveyor transfer line, where the brass sliding bearing tolerates contamination that would jam a ball guide while delivering 57 N of push.
Off-Centre Gripper Index
Shifting a small parts gripper laterally across 125 mm, relying on the ±0.1° non-rotating tolerance to keep the jaws square under an unbalanced payload.
Compact Assembly Pusher
Pushing light components into a fixture on an assembly line, using the twin-rod body to absorb side loads and the fixed TPU bumpers to soften the end of stroke.
Is the Airtac TCM Triple Axis Cylinder TCM12X125-S the Right Cylinder?
Choose this 12 mm bore when your application needs 57 N of push (42 N pull) at 0.5 MPa within a 125 mm stroke. If you require less force, step down to the Ø10 bore delivering 39 N; if moving heavier plates, step up to the Ø16 bore providing 101 N. Select the sibling TCL series with its steel-ball linear bearing instead if your task demands low-friction precision or high vertical loading rather than impact tolerance.
Remember that the guide resists rotation, not gravity; if air pressure drops, the rod drifts, so fit an external rod lock or pilot-operated check valve for fail-safe holding. This configuration includes the standard built-in magnet (S) and default PT tapered threads.
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 TCM12X125-S FAQ
At 0.5 MPa, this 12 mm bore double-acting cylinder provides 57 N of push and 42 N of pull. At 0.7 MPa, the push increases to 79 N, with a theoretical maximum force of 12 kgf.
No, it uses fixed rubber (TPU) bumpers at each end to soften the impact at stroke limits. There is no adjustable air cushion or cushion screw to set on the TC series.
