Airtac TCM Triple Axis Cylinder TCM20X175S
The AirTAC Airtac TCM Triple Axis Cylinder TCM20X175S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 175mm 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 TCM20X175S
The AirTAC TCM20X175S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. A drive piston moves between two guide rods within a single integrated body, eliminating the need for an external linear rail. This double-acting actuator generates 157 N of push and 118 N of pull at 0.5 MPa, courtesy of its Ø10 mm piston rod. With a 175 mm stroke, it is built for tasks demanding precise lateral stability.
Designed for harsh environments, the brass sliding bearing shrugs off dust, grit, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder. It holds a non-rotating tolerance of ±0.08°, keeping grippers or plates square under offset loads. The unit lands on fixed TPU bumpers at each end rather than an adjustable air cushion. Air is plumbed via 1/8" PT ports, and 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 | ±0.08° (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 (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 TCM20X175S Is Used
Sawmill Fence Positioning
With 157 N of push at 0.5 MPa, this actuator easily shifts heavy wooden guide fences. The brass sliding bearing tolerates airborne sawdust and hard impacts where a steel-ball guide would jam.
Off-Centre Gripper Slide
Holding ±0.08° non-rotating accuracy, it keeps a part-gripper square during extension. The twin guide rods absorb the torsional load of picking asymmetric components without an external rail.
Weld-Cell Part Stopper
Delivering 220 N at 0.7 MPa, it halts pallets in a dirty weld cell. The brass bearing withstands weld spatter and coolant spray, shrugging off contamination that would destroy a linear ball bushing.
Is the Airtac TCM Triple Axis Cylinder TCM20X175S the Right Cylinder?
At 0.5 MPa, this Ø20 bore yields 157 N of thrust. If you need less force, the Ø16 model provides 101 N of push; if your application requires more, the Ø25 unit delivers 245 N. Choose the sibling TCL series with its steel-ball linear bearing only when you need low friction and high precision for vertical high-load work. To match this exact actuator, specify bore 20, stroke 175, 1/8" PT ports, and the standard S magnet.
Note that if air pressure drops or the valve is centered, this cylinder will not hold its load vertically, as the guide prevents rotation but not gravity drift. You must add an external rod lock or pilot-operated 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 TCM20X175S FAQ
This double-acting cylinder delivers 157 N of push and 118 N of pull at 0.5 MPa. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf.
No. Stroke ends are damped by fixed elastomer TPU pads rather than an adjustable cushion screw. This design requires no tuning and provides reliable stopping for the 175 mm travel.
