Airtac TCM Triple Axis Cylinder TCM12X50-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM12X50-S is a genuine JIS-standard guided cylinder with a Ø12mm bore and 50mm 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 TCM12X50-S
The AirTAC TCM12X50-S is a JIS-standard twin-rod guided cylinder engineered for double-acting operation. A central Ø6 mm piston rod drives the load while twin guide rods supported by brass sliding bearings carry the radial load and moment, eliminating the need for an external linear rail. Delivering 57 N of push at 0.5 MPa, it integrates the guide and drive into one compact body.
This 12 mm bore unit holds a strict ±0.1° non-rotating tolerance, keeping a gripper or blade perfectly square under off-centre loads. The brass sliding bearing is built for dirty environments, shrugging off grit and hard knocks where a steel-ball guide would jam. Stroke termination relies on fixed TPU rubber bumpers at both ends, meaning there is no adjustable air cushion to tune. Air is plumbed via M5x0.8 ports, and the standard built-in magnet works with 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 |
| 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 TCM12X50-S Is Used
Transfer Line Gating
With 57 N of thrust at 0.5 MPa, this cylinder stops lightweight packages on a dusty transfer line, where the brass sliding bearing tolerates grit that would jam a ball guide.
Off-Centre Gripper Slide
The ±0.1° non-rotating tolerance keeps a small part gripper square during rapid side-mount pick-and-place maneuvers without needing a separate external rail.
Lab Sample Blade Stop
Delivering 79 N of push at 0.7 MPa, the twin guide rods safely support an off-centre cutting blade in a gritty lab automation station, absorbing side shocks via the brass bearing.
Is the Airtac TCM Triple Axis Cylinder TCM12X50-S the Right Cylinder?
If your application requires less force, stepping down to the Ø10 bore yields about 39 N of push at 0.5 MPa. For heavier pushing, moving up to the Ø16 bore provides 101 N at 0.5 MPa. Choose the sibling TCL series with its steel-ball linear bearing instead of this TCM if your task demands low-friction precision or high vertical load handling rather than impact tolerance. To replicate this exact unit, specify a 12 mm bore, 50 mm stroke, M5x0.8 port size, PT thread, and the standard S magnet. Note that a guided cylinder will not hold a load if air pressure drops; the rod drifts, so add an external rod lock or pilot check valve 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 TCM12X50-S FAQ
At 0.5 MPa, this 12 mm bore cylinder provides 57 N of push and 42 N of pull. At 0.7 MPa, the push increases to 79 N. The theoretical maximum force is 12 kgf.
No, there is no adjustable air cushion screw. Each end of the cylinder uses a fixed rubber TPU bumper to soften the stop. The standard built-in magnet also allows you to track position with CS1 reed or DS1 electronic switches.
