Airtac TCM Triple Axis Cylinder TCM20X35S
The AirTAC Airtac TCM Triple Axis Cylinder TCM20X35S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 35mm 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 TCM20X35S
The AirTAC TCM20X35S is a JIS-standard twin-rod guided cylinder built for double-acting operation. A central drive piston runs between two guide rods in a single integrated body, eliminating the need for an external linear rail. The unit uses a brass sliding bearing that tolerates dust, grit, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder. It delivers 157 N of push and 118 N of pull at 0.5 MPa, making it a solid choice for medium-duty positioning.
This 20 mm bore model features a Ø10 mm piston rod and 1/8" PT ports. It holds a non-rotating accuracy of ±0.08°, keeping a gripper or blade square under off-centre loads. Stroke motion ends are softened by fixed TPU rubber bumpers, meaning there is no adjustable air cushion screw to set. The standard built-in magnet works with CS1 reed or DS1 electronic switches across four sensor slots, and air can be plumbed from either the upper face or side ports.

| 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 |

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 TCM20X35S Is Used
Pallet Stop Gate
Halts moving pallets on a dusty transfer line; the brass sliding bearing shrugs off grit where a ball guide would jam, while 157 N of thrust handles the side load.
Off-Centre Gripper Slide
Picks and places uneven parts using 220 N at 0.7 MPa; the twin guide rods maintain a ±0.08° non-rotating tolerance to keep the gripper square under torque.
Weld-Cell Clamp
Positions a welding fixture in a dirty environment; fixed TPU bumpers absorb the hard end-stops without needing adjustment, and the 1/8" ports provide ample flow.
Is the Airtac TCM Triple Axis Cylinder TCM20X35S the Right Cylinder?
If 157 N of thrust at 0.5 MPa is too much, step down to the Ø16 bore which provides about 101 N of push. Need more force? The Ø25 bore gives roughly 245 N. Choose the sibling TCL series with its steel-ball linear bearing instead when your application demands low friction, extreme precision, or high vertical loading. Remember that this cylinder does not hold its load if air pressure is lost or the valve is centred; the rod will drift. Install an external rod lock or pilot-operated check valve for fail-safe positioning. This specific SKU includes the standard S magnet and default PT tapered port threads.
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 TCM20X35S FAQ
At 0.5 MPa it provides 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 tolerance, radial load, and dirty environments. The TCL uses a steel-ball linear bearing for low-friction, high-precision vertical work. The TCM has fixed rubber bumpers rather than an adjustable air cushion.
