Airtac TCM Triple Axis Cylinder TCM40X170S
The AirTAC Airtac TCM Triple Axis Cylinder TCM40X170S is a genuine JIS-standard guided cylinder with a Ø40mm bore and 170mm 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 ±0.06° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM40X170S
The AirTAC TCM40X170S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. As a double-acting drive, it generates 628 N of push and 528 N of pull at 0.5 MPa. The integrated twin guide rods eliminate the need for an external linear rail, saving space and assembly time. With a non-rotating tolerance of ±0.06°, it keeps a gripper or blade perfectly square even under offset loads. A standard built-in magnet (S) is included for position detection.
This 40 mm bore unit features a Ø16 mm piston rod and 1/8" PT ports. The brass sliding bearing is specifically engineered for harsh environments, shrugging off dust, grit, and coolant where a steel-ball guide would jam or wear prematurely. It offers roughly double the horizontal impact resistance of a plain cylinder. Stroke termination relies on fixed TPU rubber bumpers at each end, meaning there is no adjustable air cushion screw to set or maintain.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max | 128 kgf | |
Force is set by the bore and piston rod (Ø16 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 TCM40X170S Is Used
Pallet Stop Gate
Halting heavy pallets on a transfer line, the brass sliding bearing absorbs the repeated radial impacts, leveraging the 628 N push to halt loads where contamination would quickly degrade a ball guide.
Foundry Pattern Strip
Pushing sand-casting patterns out of moulds, the ±0.06° non-rotating tolerance keeps the pattern plate perfectly level during the off-centre extraction stroke.
Weld Cell Clamp
Positioning a clamp in a dirty robotic weld cell, the brass bearing shrugs off weld spatter and grit, while the Ø16 rod handles the side loading without an external slide.
Is the Airtac TCM Triple Axis Cylinder TCM40X170S the Right Cylinder?
When sizing this model, compare its 628 N thrust (at 0.5 MPa) against neighbouring bores: the Ø32 delivers about 402 N, while the Ø50 provides 982 N, allowing you to step up or down depending on your load. Choose the sister TCL series with its steel-ball linear bearing instead if your application demands low friction, extreme precision, or high vertical load handling. To match this cylinder for a replacement, specify bore 40, stroke 170, 1/8" ports, PT thread, and the standard S magnet.
Remember that the guide unit resists rotation, not gravity; if air pressure drops or the valve is centered, the rod will drift and drop. For fail-safe load holding, fit an external rod lock or a pilot-operated check valve. The 170 mm stroke is within the 250 mm standard limit for this bore.
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 TCM40X170S FAQ
At 0.5 MPa it provides 628 N of push and 528 N of pull. At 0.7 MPa the push increases to 880 N. The theoretical maximum force is 128 kgf.
No, there is no adjustable air cushion screw. Each end of the cylinder uses a fixed rubber TPU bumper to soften the impact stop. For position sensing, the standard built-in magnet works with CS1 reed or DS1 electronic switches in the four sensor slots.
