Airtac TCM Triple Axis Cylinder TCM20X150SH
The AirTAC TCM Triple Axis Cylinder TCM20X150SH is a genuine JIS-standard guided cylinder with a Ø20mm bore and 150mm 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 TCM20X150SH
The AirTAC TCM20X150SH is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. Because the drive piston operates between two integrated guide rods, it inherently resists rotation and carries side loads without needing an external linear rail. This double-acting unit delivers 157 N of push and 118 N of pull at 0.5 MPa, making it well-suited for mid-range transfer and gating tasks. The integrated guide keeps an off-centre load square, holding a tight ±0.08° non-rotating tolerance even during dynamic movements. A standard built-in magnet enables position detection.
Designed for harsh environments, the brass sliding bearing shrugs off dust, grit, and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder. It runs at 30-500 mm/s on 1/8" PT ports and features a Ø10 mm piston rod. Stroke termination relies on fixed rubber (TPU) bumpers at each end, meaning there is no adjustable air cushion or cushion screw to set or maintain. The Viton (FKM) seals accommodate wider temperature ranges, ensuring reliable operation in demanding thermal conditions.

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 TCM20X150SH Is Used
Pallet Transfer Line Stop
Using its 157 N of thrust at 0.5 MPa, this cylinder halts moving pallets on a dusty conveyor. The brass sliding bearing tolerates abrasive grit and repeated side-impacts where a ball-bearing guide would fail.
Off-Centre Gripper Slide
Holding a ±0.08° non-rotating tolerance, it keeps a parts gripper perfectly square while picking off-centre loads. The twin-rod body absorbs the twisting moment without an external guide rail.
Foundry Pattern Pusher
Pushing sand mould patterns in a hot foundry, the Viton (FKM) seals withstand elevated temperatures. The impact-resistant brass bearing survives harsh, dirty duty cycles effortlessly.
Is the Airtac TCM Triple Axis Cylinder TCM20X150SH the Right Cylinder?
When sizing this model, consider the neighbouring bores in the AirTAC range: stepping down to a Ø16 bore yields about 101 N of push at 0.5 MPa, while moving up to a Ø25 bore provides 245 N. Choose this Ø20 TCM variant when your application involves dirty environments, weld spatter, or heavy radial impacts where a steel-ball linear bearing (found on the TCL series) would jam or wear prematurely. Opt for the TCL instead if you need ultra-low friction or high-precision vertical load handling. Remember that this guided cylinder will not hold its load if air pressure drops or the valve is centered; the rod will drift. For fail-safe positioning, install an external rod lock or a pilot-operated check valve. This specific SKU includes the standard S magnet and PT tapered thread.
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 TCM20X150SH FAQ
This 20 mm bore cylinder generates 157 N of push and 118 N of pull at 0.5 MPa, reaching 220 N of push at 0.7 MPa, with a theoretical maximum force of 32 kgf. It operates on 1/8" PT ports, runs at 30-500 mm/s, and has an operating pressure range of 0.15-1.0 MPa.
Stroke termination is handled by fixed rubber (TPU) bumpers at each end that soften the mechanical stop. There is no adjustable air cushion or cushion screw on the TC series. The standard built-in magnet allows you to track rod position using CS1 reed or DS1 electronic switches in the four body slots.
