Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X125S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X125S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 125mm 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 B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X125S
The AirTAC B02-TCM32X125S is a JIS-standard, double-acting twin-rod guided cylinder built for welding-line automation. The leading "B02-" prefix marks this as AirTAC's welding-industry dedicated variant of the base TCM32X125S; mechanically it is identical, delivering 402 N of push and 302 N of pull at 0.5 MPa. A central drive piston runs between two guide rods in a single integrated body, eliminating the need for an external linear rail. The brass sliding bearing shrugs off grit, weld spatter and hard knocks, offering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam.
Precision is locked down by a ±0.06° non-rotating tolerance, keeping clamps and fixtures square under offset loads. Plumbing is simplified by two independent port groups (upper face and side) on 1/8" ports, allowing air feeds from whichever side is clear of the cell. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, and the standard built-in magnet works with CS1 reed or DS1 electronic switches across four sensor slots.

| 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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max | 82 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 B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X125S Is Used
Spot Welding Gun Clamp
Holds heavy copper tips square against a panel seam. The brass sliding bearing tolerates spatter and shop dirt that would stall a ball guide, while 402 N of push secures the joint.
Robot Cell Fixture Slide
Indexes a locating pin into a subframe inside a robotic weld cell. The ±0.06° anti-rotation tolerance keeps the pin true under off-centre loads without an external guide rail.
Welding Line Pallet Stop
Gates a moving pallet into the weld station. Twin guide rods absorb the radial impact of the arriving load, relying on fixed TPU bumpers to soften the hard stop.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X125S the Right Cylinder?
This 32 mm bore provides 402 N of thrust at 0.5 MPa. If you need less force, step down to the Ø25 model (about 245 N push); if your fixturing requires more push, the Ø40 bore yields roughly 628 N. The Ø16 piston rod and 1/8" PT ports remain fixed by this bore size. Choose the sister TCL series with its steel-ball linear bearing instead if your weld cell demands exceptionally low friction or high-precision vertical loading.
Remember that this guide resists rotation, not gravity: the rod will drift downward if air pressure is lost or the valve is centred. For fail-safe load holding during an emergency stop, add an external rod lock or a pilot-operated check valve. Replacement requires matching the 32 mm bore, 125 mm stroke, PT thread form, and the standard S magnet.
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 B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X125S FAQ
At 0.5 MPa it generates 402 N of push and 302 N of pull; at 0.7 MPa the push increases to 563 N. The theoretical maximum force is 82 kgf. It operates on filtered air between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
The B02- prefix simply designates this as AirTAC's welding-industry dedicated variant of the TCM32X125S; it shares the exact same physical specs, seals, and materials as the base model. Each end of stroke is absorbed by a fixed rubber TPU bumper—there is no adjustable air cushion or cushion screw to set.
