Airtac TCM Triple Axis Cylinder TCM40X25SH
The AirTAC Airtac TCM Triple Axis Cylinder TCM40X25SH 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 TCM40X25SH
The AirTAC TCM40X25SH is a JIS double-acting twin-rod guided cylinder featuring a robust brass sliding bearing. A central drive piston runs between two guide rods in a single integrated body, eliminating the need for an external linear rail. Generating 628 N of push and 528 N of pull at 0.5 MPa, this 40 mm bore unit is built for demanding radial loads. Its brass sliding construction shrugs off grit, coolant, and hard knocks, offering roughly twice the horizontal impact resistance of a plain cylinder where a steel-ball guide would jam.
Precision is tightly controlled with a non-rotating tolerance of ±0.06°, keeping grippers or plates square under off-centre loads. The 25 mm stroke operates at 30-500 mm/s, landing on fixed rubber TPU bumpers at each end without any adjustable air cushion screw to maintain. Featuring a standard built-in magnet, the body provides four sensor slots for CS1 reed or DS1 electronic switches. A Viton (FKM) seal extends the operating temperature range, while twin independent port groups (upper face and side) on 1/8" PT threads and a Ø16 mm piston rod simplify plumbing and mounting.

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 TCM40X25SH Is Used
Foundry Sand Mould Press
Pushing heavy sand mould patterns with 628 N of force at 0.5 MPa, where the brass sliding bearing tolerates abrasive grit and extreme heat that would destroy a ball-bearing guide.
Pallet Stop Gate
Halting loaded pallets on a transfer line using 880 N of thrust at 0.7 MPa; the twin guide rods absorb the harsh horizontal impact without bending the Ø16 mm piston rod.
Off-Centre Gripper Slide
Holding an asymmetric part square during machining thanks to the ±0.06° non-rotating tolerance, resisting torsional twist even when the workpiece is heavily loaded to one side.
Is the Airtac TCM Triple Axis Cylinder TCM40X25SH the Right Cylinder?
Selecting the TCM40X25SH provides 628 N of thrust at 0.5 MPa, striking a balance between the smaller Ø32 bore (402 N push) and the larger Ø50 bore (982 N push). If your application involves low-friction, high-precision vertical lifting rather than dirty, heavy-side-load duty, consider the sister TCL series with its steel-ball linear bearing instead. For exact replacement matching, specify the 40 mm bore, 25 mm stroke, 1/8" PT port thread, and the standard built-in magnet (S). Note that air pressure both extends and retracts this double-acting unit; it will not hold a load if air is lost or the valve is centered, so add an external rod lock or pilot-operated check valve for fail-safe positioning.
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 TCM40X25SH FAQ
At 0.5 MPa it provides 628 N of push and 528 N of pull. At 0.7 MPa the push increases to 880 N. The theoretical maximum force is 128 kgf.
No, stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. There is no air-cushion screw to set on the TC series.
