Airtac TCM Triple Axis Cylinder TCM50X125-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM50X125-S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 125mm 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 TCM50X125-S
The AirTAC TCM50X125-S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. A central drive piston runs between two guide rods in a single integrated body, eliminating the need for an external linear rail while preventing rotation. Delivering 982 N of push force at 0.5 MPa, this double-acting unit is built for demanding radial-load applications. The brass bearing shrugs off dust, grit, and hard knocks, offering about twice the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam from contamination.
Precision is maintained under off-centre loads with a non-rotating tolerance of ±0.05°, keeping grippers or plates perfectly square. The Ø20 mm piston rod operates on 1/4" ports, and two independent port groups let you feed air from the top or side without extra elbows. Stroke ends are damped by fixed TPU bumpers rather than an adjustable air cushion. A standard built-in magnet works with CS1 reed or DS1 electronic switches in the four sensor slots.

| 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 |

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 TCM50X125-S Is Used
Pallet Transfer Line Stop
Halts heavy moving pallets using 982 N of thrust. The brass sliding bearing tolerates continuous dusty impacts and side loads that would stall a ball-bearing guide.
Foundry Sand Mould Press
Compacts sand moulds under dirty, high-temperature conditions. The robust brass sleeve handles abrasive grit and knocks without jamming, maintaining a ±0.05° non-rotating accuracy.
Off-Centre Gripper Slide
Shifts an offset gripper carrying heavy parts. The integrated twin guide rods absorb the torsional moment, keeping the Ø20 rod perfectly square during part transfer.
Is the Airtac TCM Triple Axis Cylinder TCM50X125-S the Right Cylinder?
This 50 mm bore generates 982 N of thrust at 0.5 MPa. If you need less force, stepping down to the Ø40 bore yields roughly 628 N of push, while moving up to the Ø63 bore provides 1559 N for heavier duty. Choose the sister TCL series with its steel-ball linear bearing instead if your task demands low-friction precision or high vertical loading. To replace this unit, match the 50 mm bore, 125 mm stroke, 1/4" PT ports, and the standard S magnet.
Remember that air pressure drives both extension and retraction; if supply is lost or the valve centres, the rod drifts and drops. The twin-rod guide resists torsion, not gravity, so fit 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 TCM50X125-S FAQ
At 0.5 MPa it provides 982 N of push and 825 N of pull force. At 0.7 MPa the push increases to 1374 N, with a theoretical maximum force of 200 kgf. Operating pressure ranges from 0.15-1.0 MPa, and it operates at speeds of 30-500 mm/s.
No, the TC series uses a fixed rubber TPU bumper at each end to soften the stroke stop. There is no adjustable air cushion or cushion screw to set. The standard built-in magnet also allows tracking via CS1 reed or DS1 electronic switches in the four body slots.
