Airtac TCM Triple Axis Cylinder TCM20X15S
The AirTAC TCM Triple Axis Cylinder TCM20X15S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 15mm 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 TCM20X15S
The AirTAC TCM20X15S is a JIS-standard twin-rod guided cylinder featuring a brass sliding bearing. Because the drive piston runs between two integrated guide rods, it prevents rotation and carries side load without needing an external linear rail. Generating 157 N of push force at 0.5 MPa, this 20 mm bore, 15 mm stroke unit is built for short, heavy-duty movements.
The brass sliding bearing shrugs off grit, coolant, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder. It holds a tight ±0.08° non-rotating tolerance, keeping a gripper square under offset loads. A moulded rubber bumper absorbs the stop at both ends, with no air-cushion screw to set. The standard built-in magnet works with CS1 reed or DS1 electronic switches in the four body slots.

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 TCM20X15S Is Used
Pallet Transfer Line Stop
Halts heavy pallets on a dusty conveyor using 157 N of thrust at 0.5 MPa. The brass sliding bearing tolerates abrasive grit where a ball guide would jam.
Weld-Cell Clamp Arm
Clamps parts in a dirty weld cell. The twin guide rods handle the side torque from off-centre loading, while the brass bearing shrugs off weld spatter.
Off-Centre Gripper Slide
Moves a 15 mm stroke gripper that picks uneven parts. The ±0.08° non-rotating tolerance keeps the jaws square, preventing grip failure.
Is the Airtac TCM Triple Axis Cylinder TCM20X15S the Right Cylinder?
This 20 mm bore generates 157 N of thrust at 0.5 MPa. If your application needs less force, stepping down to the Ø16 bore yields about 101 N of push at 0.5 MPa. For heavier radial loads, moving up to the Ø25 bore provides 245 N of push at 0.5 MPa. The 1/8" port and Ø10 piston rod are fixed by this bore size. The code includes a standard S magnet and PT thread.
Choose the sister TCL series with its steel-ball linear bearing when you need low-friction, high-precision, or vertical high-load handling instead of impact tolerance. Note that this guided cylinder does not hold its load if air pressure is lost or the valve is centred; the rod will drift. For a fail-safe hold, 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 TCM20X15S FAQ
At 0.5 MPa it delivers 157 N of push and 118 N of pull. At 0.7 MPa the push increases to 220 N. The theoretical maximum force is 32 kgf.
The TCM uses a brass sliding bearing built for impact resistance, radial load, and dirty environments. The TCL uses a steel-ball linear bearing for low-friction, high-precision, vertical high-load tasks.
