Airtac TCM Triple Axis Cylinder TCM40X25S
The AirTAC Airtac TCM Triple Axis Cylinder TCM40X25S is a genuine JIS-standard guided cylinder with a Ø40mm bore and 25mm 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 ±0.06° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM40X25S
The AirTAC TCM40X25S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It generates 628 N of push and 528 N of pull at 0.5 MPa, driven by a Ø16 mm piston rod on 1/8" ports. Because the drive piston runs between two integrated guide rods, you get anti-rotation control holding tight to ±0.06° without bolting on a separate linear rail. This 25 mm stroke excels in short, heavy-duty transfer movements.
The brass sleeve design is built for abusive settings, shrugging off weld spatter, grit, and coolant where a steel-ball guide would jam or score. It provides roughly double the horizontal impact resistance of a conventional plain cylinder. Stroke terminations are softened by fixed TPU bumpers, meaning there is no pneumatic cushion screw to tweak. A standard internal magnet pairs with CS1 reed or DS1 electronic sensors across four body slots, and the 1/8" port thread defaults to PT.

| 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 | ±0.06° (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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max | 128 kgf | |
Force is set by the bore and piston rod (Ø16 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 TCM40X25S Is Used
Foundry Sand-Mould Press
Delivering 880 N of push at 0.7 MPa, this cylinder compacts sand moulds while the brass sliding bearing shrugs off abrasive grit that would destroy a ball guide.
Heavy Pallet Stopper
Halting a moving pallet line is easy with 628 N of thrust; the twin guide rods absorb the severe radial side-load and hard knocks without bending the main rod.
Weld-Cell Part Clamp
Holding a steel fixture square against an off-centre weld load relies on the ±0.06° non-rotating tolerance, while the brass sleeve tolerates weld spatter and coolant spray.
Is the Airtac TCM Triple Axis Cylinder TCM40X25S the Right Cylinder?
This 40 mm bore hits 628 N of thrust at 0.5 MPa. If you need slightly less force, the Ø32 bore yields about 402 N; stepping up to the Ø50 bore provides 982 N of push at the same pressure. Choose the sibling TCL series with its steel-ball linear bearing instead if your task demands low-friction precision or high vertical lifting capacity rather than sheer impact survival. Remember that air pressure drives both extension and retraction; if the supply drops, the rod will drift and drop, so fit an external rod lock or pilot-operated check valve for fail-safe holding. The exact replacement match is a 40 mm bore, 25 mm stroke, 1/8" PT port, with 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 TCM40X25S FAQ
At 0.5 MPa it provides 628 N of push and 528 N of pull. At the maximum operating pressure of 1.0 MPa, the push reaches 880 N, with a theoretical maximum force of 128 kgf. The cylinder operates at speeds of 30-500 mm/s.
Each end of the cylinder lands on a fixed rubber TPU bumper that absorbs the impact shock. There is no adjustable air cushion or cushion screw to set, keeping the unit simple and rugged for high-impact duty.
