Airtac TCM Triple Axis Cylinder TCM20X45S
The AirTAC Airtac TCM Triple Axis Cylinder TCM20X45S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 45mm 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 TCM20X45S
The AirTAC TCM20X45S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It integrates the drive piston and two guide rods into a single body, eliminating the need for an external linear rail while preventing rotation. Delivering 157 N of push force at 0.5 MPa, this double-acting unit is built for side-load and torque resistance in demanding environments.
Its brass sliding bearing shrugs off grit, coolant, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam. The Ø10 mm piston rod operates on 1/8" ports, and the non-rotating tolerance of ±0.08° keeps a gripper or blade square under off-centre loads. Stroke termination relies on fixed TPU rubber pads at each end, as there is no adjustable air cushion.

| Acting type | Double acting |
| Bearing | Brass sliding bearing |
| Port size | 1/8" |
| 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 | ±0.08° (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 TCM20X45S Is Used
Pallet Stop Gate
Halting heavy pallets on a dusty transfer line is easy with 157 N of push force. The brass sliding bearing tolerates abrasive grit and side-impact knocks where a ball guide would seize.
Off-Centre Gripper Slide
Moving a clamping gripper that pulls eccentrically is handled by the twin guide rods. The ±0.08° non-rotating tolerance keeps the tool square, while the Ø10 rod provides stable thrust.
Weld-Cell Part Pusher
Ejecting parts in a dirty weld-cell requires a cylinder that ignores spatter and debris. This model's integrated body needs no separate rail, and the fixed rubber bumpers absorb hard end-stops.
Is the Airtac TCM Triple Axis Cylinder TCM20X45S the Right Cylinder?
This 20 mm bore generates 157 N of thrust at 0.5 MPa, sitting between the smaller Ø16 (101 N) and the larger Ø25 (245 N) options, allowing you to step up or down for the exact force required. Choose the sister TCL series with its steel-ball linear bearing instead if your application demands low friction or high-precision vertical movement. The standard S magnet works with CS1 reed or DS1 electronic switches across four sensor slots. Ports are PT by default. Note that a TC does not hold its load if air pressure drops; 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 TCM20X45S FAQ
It generates 157 N of push and 118 N of pull at 0.5 MPa, and 220 N of push at 0.7 MPa, with a theoretical maximum force of 32 kgf. Operating pressure ranges from 0.15 to 1.0 MPa.
The TCM uses a brass sliding bearing built for impact tolerance and dirty environments, whereas the TCL uses a steel-ball linear bearing for low-friction precision. This model uses fixed TPU rubber bumpers at each end and has no adjustable air cushion.
