Airtac TCL Triple Axis Cylinder TCL20X85S
The AirTAC Airtac TCL Triple Axis Cylinder TCL20X85S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 85mm 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 TCL20X85S
The AirTAC TCL20X85S is a JIS-standard twin-rod guided cylinder that operates double-acting using a steel-ball linear bearing. An internal drive piston runs between two guide rods in a single integrated body, eliminating the need for an external linear slide. The steel-ball bearing provides low-friction, high-precision travel without the stick-slip of plain bearings, making it well suited for vertical lifts and accurate high-cycle tasks. Generating 157 N of push at 0.5 MPa, this 20 mm bore unit uses a Ø10 mm piston rod and 1/8" ports.
With an 85 mm stroke, the unit keeps a gripper or workplate square under off-centre loads thanks to a non-rotating tolerance of ±0.06°. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. Two independent port groups (upper face and side) let you feed air from whichever side is free without extra elbows, while four sensor slots read rod position from any face using the standard built-in magnet.

| 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 | ±0.06° (retracted) |

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 TCL20X85S Is Used
PCB handling lift
Lifts delicate electronics on a vertical carriage with 157 N of thrust, exploiting the steel-ball linear bearing for smooth, stick-slip-free travel without an external rail.
Off-centre gripper transfer
Moves parts via a side-loaded gripper while the twin guide rods and ±0.06° non-rotating tolerance keep the jaws square under moment load.
3D printer bed actuation
Positions a toolhead precisely across an 85 mm stroke, using the integrated body to save frame space and avoid aligning a separate cylinder to a guide.
Is the Airtac TCL Triple Axis Cylinder TCL20X85S the Right Cylinder?
If 157 N of thrust at 0.5 MPa is too light, the neighbouring Ø25 bore yields roughly 245 N of push; stepping down to a Ø16 bore drops the output to about 101 N. Choose the sibling TCM series with its brass sliding bearing only if your duty involves heavy radial impacts or dusty environments. To replace this unit exactly, specify bore 20, stroke 85, 1/8" PT ports, and the standard S magnet. Note that a TC does not hold its load if air pressure is lost or the valve is centred—the rod drifts and the guide resists rotation, not gravity—so fit an external rod lock or pilot check valve for a fail-safe hold.
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 TCL20X85S FAQ
At 0.5 MPa it generates 157 N of push and 118 N of pull; at 0.7 MPa the push increases to 220 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
There is no air-cushion screw to set; a moulded rubber bumper absorbs the stop at both ends. The standard built-in magnet works with AirTAC CS1 (reed) and DS1 (electronic) switches in the four body slots.
