Airtac TCM Triple Axis Cylinder TCM20X75S
The AirTAC Airtac TCM Triple Axis Cylinder TCM20X75S 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 TCM20X75S
The AirTAC TCM20X75S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It produces 157 N of push and 118 N of pull at 0.5 MPa, making it well-suited for mid-range actuation. Because the drive piston moves between two integrated guide rods, this unit prevents rotation entirely on its own, eliminating the need to align an external linear rail. With a tight non-rotating tolerance of ±0.08°, it keeps a gripper or blade perfectly square under off-centre loads.
The brass sliding bearing is specifically engineered for harsh, dirty environments. It shrugs off grit, coolant, and hard knocks, offering about twice the horizontal impact resistance of a plain cylinder. Stroke termination is handled by fixed TPU rubber bumpers at each end, meaning there is no adjustable air cushion screw to set. The standard built-in magnet works seamlessly with CS1 reed or DS1 electronic switches across the four sensor slots, and the 1/8" ports on this 20 mm bore body offer flexible pneumatic plumbing.

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 TCM20X75S Is Used
Pallet Stop Gate
Halting heavy pallets on a dusty transfer line is easy for the brass sliding bearing, which absorbs the radial impact where a ball guide would jam from contamination. The 157 N push at 0.5 MPa provides firm stopping power.
Off-Centre Gripper Slide
Picking asymmetric parts keeps the tool square thanks to the ±0.08° non-rotating tolerance. The twin guide rods carry the moment load directly, removing the need to bolt on a separate linear slide.
Foundry Pattern Push
In a sand-moulding line, grit and heat are constant. The brass sleeve handles the dirty environment with high torsional rigidity, while the 1/8" port feeds the 32 kgf theoretical force needed to seat patterns.
Is the Airtac TCM Triple Axis Cylinder TCM20X75S the Right Cylinder?
When sizing this model, consider stepping down to the Ø16 bore, which yields roughly 101 N of push at 0.5 MPa, or moving up to the Ø25 bore, which provides about 245 N of push at 0.5 MPa. This 20 mm bore sits comfortably in the middle, delivering a theoretical maximum of 32 kgf. Choose the sibling TCL series with its steel-ball linear bearing instead if your application demands exceptionally low friction, high positioning precision, or heavy vertical load handling.
Remember that this guided cylinder relies on live air pressure to hold its position; if air is lost or the valve is centred, the rod will drift, so add an external rod lock or pilot check valve for fail-safe holding. The 75 mm stroke is well within the 250 mm maximum standard stroke for this bore. The S in the TCM20X75S code denotes the standard built-in magnet, and the ports are PT (tapered) thread by default.
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 TCM20X75S FAQ
This 20 mm bore double-acting cylinder generates 157 N push and 118 N pull at 0.5 MPa, and 220 N push at 0.7 MPa. The theoretical maximum force is 32 kgf. It operates on filtered air at 0.15-1.0 MPa pressure, with a proof pressure of 1.5 MPa, and runs at speeds between 30 and 500 mm/s.
No, there is no adjustable air cushion or cushion screw. Each end of the stroke relies on a fixed rubber TPU bumper to soften the impact. This design matches the brass sliding bearing's strength in rugged, high-impact duty where delicate cushion adjustments would fail.
