Airtac TCM Triple Axis Cylinder TCM50X40-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM50X40-S is a genuine JIS-standard guided cylinder with a Ø50mm 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 TCM50X40-S
The AirTAC TCM50X40-S 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 while absorbing heavy side loads and torsion. This double-acting 50 mm bore unit generates 982 N of push force at 0.5 MPa, supported by a Ø20 mm piston rod on 1/4" ports.
Designed for harsh environments, the brass bearing shrugs off grit, coolant, and hard knocks, offering about twice the horizontal impact resistance of a plain cylinder where a steel-ball guide would jam. The twin-rod geometry maintains a non-rotating tolerance of ±0.05°, keeping a gripper or plate perfectly square under off-centre loads. Stroke termination is softened by fixed TPU rubber bumpers at each end, as this series uses no adjustable air cushion. A standard built-in magnet pairs with CS1 reed or DS1 electronic switches across four sensor slots, and PT thread ports are fitted as standard.

| Acting type | Double acting |
| Bearing | Brass sliding bearing |
| Port size | 1/4" |
| 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 | ±0.05° (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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max | 200 kgf | |
Force is set by the bore and piston rod (Ø20 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 TCM50X40-S Is Used
Heavy Pallet Stop
With 982 N of thrust at 0.5 MPa, this cylinder halts heavy pallets on a dusty transfer line, where the brass sliding bearing tolerates abrasive grit that would destroy a ball guide.
Off-Centre Gripper Slide
The ±0.05° non-rotating tolerance keeps a heavy-duty gripper square while lifting asymmetric parts, absorbing the torsional load without needing a separate external guide rail.
Foundry Pattern Push
In a hot, contaminant-filled foundry, the brass bearing shrugs off sand and scale while delivering 1374 N of push at 0.7 MPa to position heavy mould patterns reliably.
Is the Airtac TCM Triple Axis Cylinder TCM50X40-S the Right Cylinder?
When sizing this model, consider stepping down to a Ø40 bore for roughly 628 N of push at 0.5 MPa, or moving up to a Ø63 bore for 1559 N if your application requires greater thrust. Choose the sister TCL series with its steel-ball linear bearing instead if your task demands low-friction precision or vertical high-load handling rather than impact tolerance.
Note that the TCM50X40-S will not hold its load vertically if air pressure drops or the valve is centered; the guide resists rotation but not gravity, so fit an external rod lock or pilot-operated check valve for fail-safe positioning. This 40 mm stroke is a standard length, and the unit includes the standard S magnet and PT port threads.
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 TCM50X40-S FAQ
This 50 mm bore double-acting cylinder provides 982 N of push and 825 N of pull at 0.5 MPa, 1374 N of push at 0.7 MPa, with a theoretical maximum force of 200 kgf.
A moulded rubber bumper absorbs the stop at both ends, with no air-cushion screw to set. This fixed TPU bumper softens the impact but cannot be adjusted like a standard pneumatic cushion.
