Airtac TCM Triple Axis Cylinder TCM80X70S
The AirTAC Airtac TCM Triple Axis Cylinder TCM80X70S is a genuine JIS-standard guided cylinder with a Ø80mm bore and 70mm 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 TCM80X70S
The AirTAC TCM80X70S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. A drive piston moves between two guide rods within a single integrated body, actively preventing rotation and absorbing side load so no external linear rail is required. Generating 2513 N of push and 2268 N of pull at 0.5 MPa, this double-acting unit is built for heavy radial duty. The brass sleeve shrugs off weld spatter, coolant, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide would jam.
This 80 mm bore model secures an off-centre gripper or heavy plate square under load via a non-rotating tolerance of ±0.05°. The Ø25 mm piston rod and Ø30 mm guide rods feed air through 3/8" ports, while operational velocity spans 50-400 mm/s. Stroke termination relies on fixed TPU elastomer pads at each end, meaning there is no air-cushion needle to adjust. An integrated magnet comes standard, enabling position tracking via CS1 reed or DS1 electronic switches in any of the four sensor grooves.

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 TCM80X70S Is Used
Foundry Sand Mould Press
Tolerates extreme heat and abrasive grit while packing sand moulds, leveraging 2513 N of thrust at 0.5 MPa where a rolling ball guide would seize from contamination.
Heavy Pallet Stopper
Halts loaded pallets on a transfer line by absorbing the radial shock via the brass sliding bearing, preventing rod rotation under off-centre impact.
Weld Cell Clamp
Positions heavy welding fixtures squarely with a ±0.05° non-rotating accuracy, shrugging off weld spatter and coolant spray without jamming.
Is the Airtac TCM Triple Axis Cylinder TCM80X70S the Right Cylinder?
Select the TCM80X70S when your application demands high thrust alongside severe impact or contamination resistance. It delivers 2513 N of thrust at 0.5 MPa, while the smaller Ø63 bore provides 1559 N and the maximum Ø100 bore yields 3927 N, allowing you to step up or down in force as needed. The built-in magnet (S) and PT thread are standard on this SKU.
If your task instead requires low-friction precision or high vertical load capacity, the sibling TCL series with its steel-ball linear bearing is the better choice. Remember that this guide resists rotation, not gravity: the rod will drift downward if air pressure is lost or the valve is centered, so deploy an external rod lock or pilot-operated check valve for fail-safe position holding.
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 TCM80X70S FAQ
At 0.5 MPa it provides 2513 N of push and 2268 N of pull. At 0.7 MPa the push increases to 3519 N, with a theoretical maximum force of 513 kgf. Operating pressure is 0.15-1.0 MPa and speed ranges from 50-400 mm/s.
Moulded rubber TPU bumpers absorb the impact at both stroke ends. The TC series does not feature an adjustable air cushion or cushion screw, relying entirely on these fixed elastomer pads to soften the mechanical stop.
