The AirTAC Airtac TCM Triple Axis Cylinder TCM25X20SG is a genuine JIS-standard guided cylinder with a Ø25mm bore and 20mm 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.
The AirTAC TCM25X20SG is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It integrates the drive piston and two guide rods into a single body, eliminating the need for an external linear rail. Generating 245 N of push force at 0.5 MPa, this double-acting unit is tailored for short-stroke gating and clamping. The brass sleeve construction shrugs off weld spatter, grit, and hard mechanical knocks, offering roughly twice the horizontal impact resistance of a conventional plain cylinder.
Precision is locked in by a non-rotating tolerance of ±0.08°, keeping gripper jaws or work plates perfectly square under offset loads. The Ø12 mm piston rod is driven through 1/8" G (BSPP) ports, while fixed TPU bumpers absorb end-of-stroke impacts without requiring any air-cushion adjustment. Four sensor slots accommodate CS1 reed or DS1 electronic switches to track the standard built-in magnet.

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.
| 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.

Sister type: TCL25X20 (steel-ball linear bearing, lower friction & higher precision). Thread codes: blank = PT · G · T = NPT.
Tolerates spatter and contamination where a steel-ball guide would jam, using its 245 N push to hold heavy steel brackets firmly during robotic welding.
The brass sliding bearing survives abrasive dust while cycling the 20 mm stroke to halt pallets, resisting deflection with its ±0.08° non-rotating accuracy.
Supports the side load of an offset part pick with its integrated twin guide rods, keeping the gripper square without needing a separate linear rail.
When sizing this actuator, compare its 245 N thrust (at 0.5 MPa) against adjacent bores: the smaller Ø20 yields 157 N of push, whereas stepping up to the Ø32 provides 402 N. Choose this Ø25 model when your application demands moderate force with high impact tolerance in a dirty environment. If your task instead requires low-friction movement, extreme vertical lifting, or high-precision linear guiding, the sister TCL series with its steel-ball bearing is the better fit. Keep in mind that the guide prevents rod rotation but will not hold a load vertically if air pressure drops; install an external rod lock or pilot-operated check valve for fail-safe positioning. This specific SKU specifies a 20 mm stroke and G-thread ports.
Quick checklist
It generates 245 N of push and 189 N of pull at 0.5 MPa, increasing to 344 N of push at 0.7 MPa, with a theoretical maximum force of 50 kgf. The operating pressure range is 0.15-1.0 MPa, and it runs at speeds between 30 and 500 mm/s.
No, stroke ends are damped by fixed elastomer TPU pads rather than an adjustable cushion. There is no cushion screw to set. Additionally, the standard built-in magnet works with CS1 (reed) and DS1 (electronic) switches across four available sensor slots.
