Airtac TCM Triple Axis Cylinder TCM16X20-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM16X20-S is a genuine JIS-standard guided cylinder with a Ø16mm 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 ±0.09° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM16X20-S
The AirTAC TCM16X20-S is a JIS-standard twin-rod double-acting guided cylinder integrating a drive piston between two guide rods in a single body. It replaces an external linear slide by carrying side load and torque directly. A brass sliding bearing provides roughly double the horizontal impact resistance of a plain cylinder, shrugging off dust and hard knocks where a steel-ball guide would jam. Generating 101 N of push at 0.5 MPa, it suits compact gating tasks.
This 16 mm bore unit features an Ø8 mm piston rod and M5x0.8 ports. It holds a non-rotating tolerance of ±0.09°, keeping a gripper or blade square under off-centre loads. Stroke termination relies on fixed TPU elastomer pads at each end, 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.

| 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 | ±0.09° (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 (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 101 N | 75 N |
| 0.7 MPa | 141 N | — |
| Max | 21 kgf | |
Force is set by the bore and piston rod (Ø8 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 TCM16X20-S Is Used
Sawdust Ejector Gate
Tolerates gritty sawdust and hard knocks on a transfer line where a ball bearing would jam, using 101 N of push to divert moving wood blocks.
Off-Centre Part Stripper
Keeps an asymmetric stripper plate square during ejection, leveraging the ±0.09° non-rotating accuracy to prevent binding under an unbalanced load.
Coolant-Exposed Stopper
Brass sliding bearings shrug off contaminated coolant splash in a machining cell, providing durable 141 N stopping force at 0.7 MPa without external rails.
Is the Airtac TCM Triple Axis Cylinder TCM16X20-S the Right Cylinder?
Select this 16 mm bore when your application needs 101 N of thrust at 0.5 MPa (141 N at 0.7 MPa) within a compact footprint. If you require less force, step down to the Ø12 bore providing 57 N; for heavier pushing, step up to the Ø20 bore yielding 157 N. Choose the sibling TCL series with its steel-ball linear bearing instead if your duty demands low friction and high precision rather than impact tolerance. To replace this unit, match the 16 mm bore, 20 mm stroke, M5x0.8 port, PT thread, and standard S magnet.
Remember that this guided cylinder will not hold a load if air pressure drops or the valve centers, as the rod will drift. For fail-safe vertical holding, install an external rod lock or a pilot-operated check valve.
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 TCM16X20-S FAQ
At 0.5 MPa, it generates 101 N of push and 75 N of pull. At 0.7 MPa, the push increases to 141 N. The maximum theoretical force is 21 kgf.
The TCM uses a brass sliding bearing built for impact and dirty environments, whereas the TCL uses a steel-ball bearing for low-friction precision. Both ends of travel use fixed rubber TPU bumpers, with no adjustable air cushion screw present.
