Airtac TCM Triple Axis Cylinder TCM50X225-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM50X225-S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 225mm 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 ±0.05° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM50X225-S
The AirTAC TCM50X225-S is a JIS-standard twin-rod guided cylinder engineered for demanding double-acting linear motion. A central drive piston operates between two integrated guide rods fitted with brass sliding bearings. This architecture eliminates the need for an external linear rail, absorbing radial loads and torsional moments directly within its own frame. Delivering 982 N of push and 825 N of pull at 0.5 MPa, it carries substantial weight while maintaining a strict non-rotating tolerance of ±0.05° to keep blades or tooling perfectly square under offset loads.
Built for harsh environments, the brass sliding bearing shrugs off weld spatter, coolant, and abrasive grit that would easily jam a steel-ball guide. The Ø20 mm piston rod feeds through 1/4" ports, offering high flow for rapid cycling at 30-500 mm/s. Stroke termination relies on fixed TPU elastomer pads at each end, absorbing shock without any air-cushion needle to adjust. The standard integrated magnet enables position tracking via CS1 reed or DS1 electronic switches in any of the four sensor channels. Ports follow the default PT tapered standard.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max | 200 kgf | |
Force is set by the bore and piston rod (Ø20 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 TCM50X225-S Is Used
Foundry Sand Mould Press
Tolerates extreme heat and abrasive sand dust where a ball guide would seize, using its 982 N push at 0.5 MPa to compact heavy foundry moulds square to the pattern.
Heavy Pallet Stopper Gate
Halts loaded pallets on a transfer line by absorbing the hard horizontal impact via its brass sliding bearing, maintaining alignment within ±0.05° despite the off-centre collision.
Weld Cell Clamp Slide
Resists weld spatter and grinding grit in robotic fabrication cells, driving a 225 mm stroke to position heavy clamping fixtures with 1374 N of thrust at 0.7 MPa.
Is the Airtac TCM Triple Axis Cylinder TCM50X225-S the Right Cylinder?
Selecting this 50 mm bore makes sense when your application requires roughly 982 N of thrust at 0.5 MPa. If you need slightly less force, stepping down to a Ø40 bore yields 628 N of push. Conversely, moving up to a Ø63 bore provides 1559 N for heavier mechanisms. The 225 mm stroke falls well within the 250 mm maximum standard stroke limit for this bore, ensuring readily available dimensions. Choose the sibling TCL series instead if your workflow demands extreme vertical precision, as its steel-ball linear bearing offers lower friction than this brass sliding sleeve.
Because this is a double-acting pneumatic actuator, the rod will drift downward and drop the payload if air pressure is lost or the directional valve is centered. The twin-rod assembly resists rotation, not gravity. To maintain a fail-safe hold on a vertical lift, install an external pneumatic rod lock or a pilot-operated check valve. When ordering replacements, match the 50 mm bore, 225 mm stroke, 1/4" port size, PT thread form, 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 TCM50X225-S FAQ
At 0.5 MPa, this double-acting cylinder generates 982 N of push and 825 N of pull. When supplied with 0.7 MPa, the push force increases to 1374 N. The absolute maximum theoretical force is 200 kgf.
No, there is no adjustable air cushion or cushion screw. Each end of the stroke is damped by a fixed rubber TPU bumper that softens the mechanical stop. This design requires no manual tuning.
