Airtac TCM Triple Axis Cylinder TCM25X30S
The AirTAC Airtac TCM Triple Axis Cylinder TCM25X30S is a genuine JIS-standard guided cylinder with a Ø25mm bore and 30mm 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 TCM25X30S
The AirTAC TCM25X30S is a JIS-standard twin-rod guided cylinder that integrates a drive piston between two guide rods in a single body. Because the guide unit itself prevents rotation and absorbs side loading, you can skip the alignment work of fitting a separate linear rail. The brass sliding bearing is built for harsh duty, shrugging off dust, grit, and hard knocks with roughly double the horizontal impact resistance of a plain cylinder. Delivering 245 N of push at 0.5 MPa, this double-acting unit is tailored for short 30 mm movements.
Precision is locked in by a ±0.08° non-rotating tolerance, keeping an off-centre gripper or blade square under load. A Ø12 mm piston rod and 1/8" ports provide robust plumbing and thrust capacity. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, simplifying setup. The standard built-in magnet feeds position signals to CS1 reed or DS1 electronic switches mounted in any of the four sensor slots, while two independent port groups let you feed air from the upper face or side without extra elbows.

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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 189 N |
| 0.7 MPa | 344 N | — |
| Max | 50 kgf | |
Force is set by the bore and piston rod (Ø12 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 TCM25X30S Is Used
Pallet Transfer Line Stop
Halts moving pallets on a dusty conveyor using 245 N of thrust at 0.5 MPa. The brass sliding bearing tolerates the abrasive environment and shock loading where a steel-ball guide would jam.
Off-Centre Gripper Slide
Actuates a part gripper with a 30 mm stroke while maintaining a ±0.08° non-rotating tolerance. The twin guide rods carry the off-centre moment load without needing an external rail.
Weld-Cell Clamp Positioning
Drives a clamping arm in a dirty welding environment. The brass bearing shrugs off weld spatter and grit, and the fixed rubber bumpers absorb the hard end-of-stroke impacts.
Is the Airtac TCM Triple Axis Cylinder TCM25X30S the Right Cylinder?
This 25 mm bore strikes a balance between compact size and meaningful force, generating 245 N of thrust at 0.5 MPa. If your application is lighter, the neighbouring Ø20 bore provides about 157 N of push; for heavier pushing, stepping up to the Ø32 bore yields roughly 402 N. If your priority is low-friction precision or vertical high-load handling rather than impact tolerance, the sister TCL series with its steel-ball linear bearing is the better route. To replace this unit, match the 25 mm bore, 30 mm stroke, 1/8" port, PT thread, and the standard S magnet.
Keep in mind the guide resists rotation but not gravity: if air pressure drops or the valve is centred, the rod will drift downward. For a fail-safe hold, install an external rod lock or a pilot-operated check valve.
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 TCM25X30S FAQ
At 0.5 MPa, this 25 mm bore cylinder provides 245 N of push and 189 N of pull. At 0.7 MPa, the push force increases to 344 N. The theoretical maximum force is 50 kgf.
The TCM uses a brass sliding bearing for impact and radial load tolerance in dirty environments, whereas the TCL uses a steel-ball linear bearing for low-friction, high-precision tasks. This model dampens stroke ends using fixed TPU bumpers and has no adjustable air cushion screw.
