Airtac TCM Triple Axis Cylinder TCM80X250S
The AirTAC Airtac TCM Triple Axis Cylinder TCM80X250S is a genuine JIS-standard guided cylinder with a Ø80mm bore and 250mm 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 TCM80X250S
The AirTAC TCM80X250S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. A central drive piston runs between two Ø30 mm guide rods integrated into a single body, completely eliminating the need for an external linear rail while delivering 2513 N of push at 0.5 MPa. Because the guide unit inherently prevents rotation and carries side loads, it easily manages heavy torque and radial forces up to the datasheet limit for this 250 mm stroke. The brass sliding bearing shrugs off dust, grit, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide would wear or jam from contamination.
This double-acting actuator moves at 50-400 mm/s and uses a Ø25 mm piston rod with 3/8" PT ports. It maintains a tight ±0.05° non-rotating tolerance, keeping any gripper or blade perfectly square under off-centre loads. Stroke termination is handled by fixed TPU rubber bumpers at each end rather than an adjustable air cushion. The standard built-in magnet allows position tracking via 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 (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max | 513 kgf | |
Force is set by the bore and piston rod (Ø25 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 TCM80X250S Is Used
Foundry Sand Mould Press
Survives hot, abrasive environments where grit would destroy a ball guide, using its 2513 N push to compact sand moulds squarely without rotating.
Heavy Pallet Stopper
Halts heavy inbound pallets on a transfer line, absorbing the hard side-impact via the brass sliding bearing while maintaining a ±0.05° non-rotating tolerance.
Sawmill Fence Positioner
Pushes heavy wood-cutting guides into place in a dusty, high-debris mill, relying on the Ø25 mm piston rod and twin Ø30 mm guide rods to handle the radial load.
Is the Airtac TCM Triple Axis Cylinder TCM80X250S the Right Cylinder?
Selecting the TCM80X250S provides 2513 N of push and 2268 N of pull at 0.5 MPa, peaking at 3519 N push at 0.7 MPa with a theoretical maximum of 513 kgf. If you need slightly less force, the adjacent Ø63 bore generates 1559 N of push at 0.5 MPa; since Ø80 is the second-largest available size, the only step up is the Ø100 bore, which delivers 3927 N of push at 0.5 MPa. Choose the sister TCL series with its steel-ball linear bearing instead if your application demands low-friction, high-precision movement or vertical high-load handling rather than heavy impact resistance.
Remember that this cylinder does not hold its load if air pressure drops or the valve is centered, as the rod will drift and the guide resists rotation, not gravity. For a fail-safe hold, install an external rod lock or a pilot-operated check valve. This configuration includes the standard built-in magnet (S) and PT threaded 3/8" ports. The 250 mm stroke is the maximum standard length for this bore, meaning any longer requirement would be a non-standard, made-to-order unit.
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 TCM80X250S FAQ
At 0.5 MPa, this double-acting cylinder generates 2513 N of push and 2268 N of pull. When pressure increases to 0.7 MPa, the push force reaches 3519 N. The theoretical maximum force for this 80 mm bore is 513 kgf.
Each end of the stroke lands on a fixed TPU rubber bumper that softens the mechanical stop. There is no adjustable air cushion or cushion screw to tune on this series, simplifying setup in dirty environments.
