Airtac TCL Triple Axis Cylinder TCL20X40-S
The AirTAC Airtac TCL Triple Axis Cylinder TCL20X40-S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 40mm stroke on twin guide rods. Its integrated steel-ball linear bearing gives low-friction, high-precision travel — well suited to vertical lifts and high-load, high-accuracy moves, holding the tool square to ±0.06° of rotation without any external linear guide.

About the Airtac TCL Triple Axis Cylinder TCL20X40-S
The AirTAC TCL20X40-S is a JIS-standard twin-rod double-acting guided cylinder featuring an integrated steel-ball linear bearing. A center drive piston runs between two guide rods, eliminating the need to align a separate external linear slide. This compact 20mm bore unit delivers 157N of push force at 0.5MPa, while the precision ball bearing ensures smooth, stick-slip-free vertical travel and accurate high-cycle positioning.
The twin guide unit provides a non-rotating tolerance of ±0.06°, keeping a gripper or workplate perfectly square under off-centre loads. It features a Ø10mm piston rod and 1/8" PT ports. Stroke termination relies on fixed TPU rubber bumpers at both ends to absorb impact, as no adjustable air cushion is present. The standard built-in magnet works seamlessly with CS1 reed or DS1 electronic switches across four sensor slots, and dual independent upper and side port groups simplify 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 TCL Triple Axis Cylinder TCL20X40-S Is Used
PCB Handling Lift
Raises delicate electronic panels using 157N of thrust at 0.5MPa. The steel-ball linear bearing ensures smooth, stick-slip-free vertical motion without needing a separate rail.
Off-Centre Gripper Transfer
Moves parts via an offset gripper while maintaining a ±0.06° non-rotating tolerance. The twin guide rods keep the jaws square under moment loads during transfers.
3D Printer Head Change
Actuates a tool carriage with high precision. The four sensor slots accept DS1 electronic switches for exact positioning, while the fixed TPU bumpers soften end stops.
Is the Airtac TCL Triple Axis Cylinder TCL20X40-S the Right Cylinder?
When sizing this 20mm bore unit, consider stepping down to a Ø12 bore which provides roughly 57N of push at 0.5MPa, or moving up to a Ø25 bore which generates 245N at 0.5MPa. Choose the TCL steel-ball linear bearing for low-friction precision vertical lifts, but switch to the TCM series if your application involves heavy radial impacts or dusty environments requiring a brass sliding bearing. For replacement, match the 20mm bore, 40mm stroke, 1/8" port, PT thread, and standard S magnet. Remember that this guided cylinder will drift and drop if air pressure is lost or the valve is centered, as the rods resist rotation but not gravity; install an external rod lock or pilot check valve for fail-safe load 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 TCL Triple Axis Cylinder TCL20X40-S FAQ
At 0.5MPa, this 20mm bore double-acting cylinder generates 157N of push force and 118N of pull force. At 0.7MPa, the push increases to 220N. The maximum theoretical force is 32kgf at 1.0MPa.
No, the TC series uses fixed rubber TPU bumpers at each end to soften the stroke termination. There is no adjustable air cushion or cushion screw to set, which simplifies setup.
