Airtac TCM Triple Axis Cylinder TCM20X75SH
The AirTAC Airtac TCM Triple Axis Cylinder TCM20X75SH is a genuine JIS-standard guided cylinder with a Ø20mm 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 ±0.08° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM20X75SH
The AirTAC TCM20X75SH is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It delivers 157 N of push and 118 N of pull at 0.5 MPa, making it well-suited for medium-duty positioning and gating tasks across a 75 mm travel. Because the guide rods and drive piston share one integrated body, you skip the alignment work of matching a separate cylinder to an external linear rail. The brass bearing shrugs off grit, weld spatter, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam from contamination.
Precision is locked in by a ±0.08° non-rotating tolerance, keeping a gripper or blade square under off-centre loads. The unit is double-acting, runs on 1/8" PT ports, and carries a Ø10 mm piston rod. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. A standard built-in magnet works with CS1 reed or DS1 electronic switches in the four body slots, and Viton (FKM) seals extend the operating temperature range for hotter environments.

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 (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max | 32 kgf | |
Force is set by the bore and piston rod (Ø10 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 TCM20X75SH Is Used
Pallet Transfer Line Stop
Halts moving pallets on a dusty conveyor using 157 N of push force at 0.5 MPa. The brass sliding bearing tolerates the repeated side impacts and grit where a ball guide would wear prematurely.
Off-Centre Gripper Slide
Transfers an asymmetric part over 75 mm with a ±0.08° non-rotating tolerance, keeping the gripper square. The twin-rod body absorbs the torsional moment without needing an external rail.
Weld Cell Clamp Positioner
Positions a clamp in a dirty weld cell. The integrated guide resists weld spatter and knocks, while the Viton seals handle the ambient heat, delivering 220 N of thrust at 0.7 MPa.
Is the Airtac TCM Triple Axis Cylinder TCM20X75SH the Right Cylinder?
This Ø20 bore provides 157 N of thrust at 0.5 MPa. If your application needs less force, stepping down to the Ø16 bore yields about 101 N of push, while moving up to the Ø25 bore delivers roughly 245 N. Choose the sibling TCL series with its steel-ball linear bearing instead if your job demands low-friction movement, high-precision vertical handling, or very heavy lifting. To replicate this unit, specify the 20 mm bore, 75 mm stroke, 1/8" PT thread, and the standard S magnet. Remember that a TCM does not hold its load if air pressure is lost or the valve is centred, as the rod will drift; the guide resists rotation, not gravity. For a fail-safe hold, add an external rod lock or a pilot-operated check valve.
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 TCM20X75SH FAQ
It generates 157 N of push and 118 N of pull at 0.5 MPa, and 220 N of push at 0.7 MPa, with a theoretical maximum force of 32 kgf. The operating speed ranges from 30 to 500 mm/s.
Each end lands on a fixed TPU rubber bumper that softens the stop. There is no adjustable air cushion or cushion screw to set. The standard built-in magnet works with CS1 reed or DS1 electronic switches in the four sensor slots.
