Airtac TCM Triple Axis Cylinder TCM20X90S
The AirTAC Airtac TCM Triple Axis Cylinder TCM20X90S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 90mm 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 TCM20X90S
The AirTAC TCM20X90S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. Operating double-acting via a Ø10 mm central piston rod, it generates 157 N of push and 118 N of pull at 0.5 MPa. The integrated twin guide rods completely remove the need for an external linear slide, saving valuable assembly space and alignment time. With a non-rotating accuracy of ±0.08°, it keeps grippers or tooling perfectly square under offset loads.
Designed for tough environments, the brass sleeve bearing tolerates dust, coolant splashes, and hard mechanical knocks far better than a steel-ball guide. A moulded rubber bumper absorbs the stop at both ends, with no air-cushion screw to set. You can feed air from either the upper face or side ports thanks to dual plumbing groups, while the standard built-in magnet pairs directly with CS1 reed or DS1 electronic switches in any of the four sensor 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 TCM20X90S Is Used
Pallet Transfer Stop
Delivering 157 N of push, this cylinder halts heavy pallets on a dusty transfer line. The brass sliding bearing shrugs off wood grit and continuous side-knocking where a ball guide would jam.
Off-Centre Gripper Slide
With a ±0.08° non-rotating tolerance, the twin rods keep an offset gripper square while lifting asymmetrical parts. The Ø10 mm rod and 1/8" ports provide responsive actuation for pick-and-place cycles.
Weld-Cell Clamp
Tolerating weld spatter and coolant mist, the brass sleeve bearing provides the torsional rigidity needed to clamp parts securely in a robotic weld cell, delivering 220 N of force at 0.7 MPa.
Is the Airtac TCM Triple Axis Cylinder TCM20X90S the Right Cylinder?
If 157 N of thrust is insufficient for your payload, stepping up to the Ø25 bore yields roughly 245 N of push at 0.5 MPa. Conversely, if your application requires less force, dropping down to the Ø16 bore provides about 101 N. Choose the sister TCL series instead when you need low-friction steel-ball precision for vertical high-load work. Remember that this unit will not hold a load if air pressure is lost; fit an external rod lock or pilot-operated check valve for fail-safe positioning. This specific SKU features PT tapered thread ports and the standard S magnet.
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 TCM20X90S FAQ
At 0.5 MPa, it provides 157 N of push and 118 N of pull. 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 pads rather than an adjustable cushion. The twin guide rods resist rotation to ±0.08°, but a rod lock is required if the load must stay put without live air pressure.
