Airtac TCM Triple Axis Cylinder TCM80X40S
The AirTAC Airtac TCM Triple Axis Cylinder TCM80X40S is a genuine JIS-standard guided cylinder with a Ø80mm bore and 40mm 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 TCM80X40S
The AirTAC TCM80X40S 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 in a single integrated body, completely eliminating the need for an external linear rail. Delivering 2513 N of push force at 0.5 MPa, this double-acting unit is built for punishing environments. The brass bearing shrugs off weld spatter, dust and coolant where a steel-ball guide would jam, offering roughly double the horizontal impact resistance of a plain cylinder.
Precision is maintained under harsh conditions, with a non-rotating tolerance of ±0.05° keeping heavy plates or blades square against off-centre loads. The Ø25 mm piston rod is driven via 3/8" ports, operating at 50-400 mm/s. Stroke termination is softened by fixed TPU bumpers at both ends, as this series uses no adjustable air cushion. The standard built-in magnet allows position detection, and precision locating holes ensure repeatable mounting without re-teaching.

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 TCM80X40S Is Used
Foundry Mould Pattern Push
With 2513 N of thrust, this cylinder shifts heavy sand mould patterns. The brass sliding bearing tolerates extreme heat and abrasive grit that would destroy a ball guide.
Heavy Pallet Stopper Gate
Halting loaded pallets on a transfer line subjects the rod to severe radial impact. The twin guide rods and impact-tolerant brass bearing absorb these hard knocks effortlessly.
Weld Cell Clamp Positioning
Clamping thick steel frames in a robotic weld cell exposes the mechanism to spatter and slag. The fixed TPU bumpers and brass bearing survive this hostile environment while maintaining ±0.05° accuracy.
Is the Airtac TCM Triple Axis Cylinder TCM80X40S the Right Cylinder?
Selecting the TCM80X40S provides 2513 N of thrust at 0.5 MPa. If your application requires less force, stepping down to the Ø63 bore yields 1559 N of push; conversely, scaling up to the Ø100 bore provides 3927 N. When your task demands low-friction precision or high vertical load capacity rather than impact tolerance, the sister TCL series with its steel-ball linear bearing is the superior choice.
Note that air pressure drives both extension and retraction; if pressure drops, the rod will drift and drop, as the guide resists rotation but not gravity. For fail-safe holding, install an external rod lock or pilot-operated check valve. This specific SKU includes the standard magnet (S) and PT tapered ports. The 40 mm stroke falls well within the 250 mm maximum, making it a stock configuration.
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 TCM80X40S FAQ
At 0.5 MPa, this 80 mm bore cylinder generates 2513 N of push and 2268 N of pull. At 0.7 MPa, the push force reaches 3519 N, with a theoretical maximum force of 513 kgf. It operates between 0.15 and 1.0 MPa, runs at 50-400 mm/s, and uses a 3/8" port.
This cylinder uses fixed rubber TPU bumpers at each end to soften the impact at stroke termination. It does not feature an adjustable air cushion or cushion screw, which suits dirty, high-impact environments where adjustment screws might freeze up from contamination.
