Airtac TCM Triple Axis Cylinder TCM40X75-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM40X75-S is a genuine JIS-standard guided cylinder with a Ø40mm bore and 75mm 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 TCM40X75-S
The AirTAC TCM40X75-S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. A central drive piston operates between two guide rods within a single integrated body, actively preventing rotation and absorbing side load. This configuration entirely removes the need for an external linear rail. Generating 628 N of push force at 0.5 MPa, it carries an off-centre load with a non-rotating accuracy of ±0.06°. The Ø16 mm piston rod and 1/8" port size provide efficient pneumatic flow for this 75 mm stroke unit.
Designed for harsh environments, the brass sliding bearing shrugs off dust, weld spatter, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder. Stroke termination relies on fixed rubber TPU bumpers at each end, meaning there is no adjustable air cushion or cushion screw to maintain. The standard built-in magnet supports CS1 reed or DS1 electronic switches across four sensor slots. Ports are PT threaded by default, accessible from either the upper face or side without extra elbows.

| Bearing | Brass sliding bearing |
| Port size | 1/8" |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Non-rotating tolerance | ±0.06° (retracted) |
| Cushion | Rubber bumper |

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 TCM40X75-S Is Used
Pallet Stop Gate
Halting heavy pallets on a dusty transfer line is ideal for this cylinder. The brass sliding bearing tolerates grit where a ball guide would jam, while the 628 N push at 0.5 MPa easily halts moving loads.
Weld Cell Clamp
Applying an off-centre clamping force in a weld cell exposes the cylinder to spatter and impacts. The TCM40X75-S handles this radial load with ±0.06° non-rotating precision, keeping the clamp face square.
Foundry Pattern Push
Pushing sand-mould patterns foundry-side involves hard knocks and debris. This cylinder's twin-rod brass bearing provides the necessary torsional rigidity and impact survival for 75 mm stroke actuation.
Is the Airtac TCM Triple Axis Cylinder TCM40X75-S the Right Cylinder?
When sizing this unit, consider stepping down to a Ø32 bore which yields 402 N of push at 0.5 MPa, or moving up to a Ø50 bore that provides 982 N. The Ø40 strikes a balance for medium radial loads. Choose the sister TCL series with its steel-ball linear bearing instead if your application demands low-friction movement or high-precision vertical handling. For this specific SKU, the built-in magnet (S) is standard, and the port thread form is PT.
Remember that guided cylinders do not hold a load unpowered; if air pressure drops or the valve centres, the rod will drift. The guide resists torsion, not gravity, so fit an external rod lock or pilot-operated check valve when fail-safe positioning is mandatory.
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 TCM40X75-S FAQ
It generates 628 N of push and 528 N of pull at 0.5 MPa, and 880 N of push at 0.7 MPa. The theoretical maximum force is 128 kgf. The twin guide rods hold a non-rotating tolerance of ±0.06°.
There is no adjustable air cushion; each end of stroke lands on a fixed TPU rubber bumper. The standard built-in magnet works with AirTAC CS1 reed switches or DS1 electronic sensors mounted in any of the four body slots.
