Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X25S
The AirTAC B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X25S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 25mm 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-TCM32X25S
The B02-TCM32X25S is AirTAC's welding-industry dedicated variant of the TCM32X25S, engineered for robot cells and clamping fixtures. The B02- prefix simply denotes this welding automation scope; mechanically, it is a standard JIS guided twin-rod cylinder featuring a brass sliding bearing. A central drive piston runs between two guide rods in a single integrated body, generating 402 N of push at 0.5 MPa. Because the guide unit prevents rotation, no external linear rail is needed, saving space and alignment labor.
This model's brass sliding bearing shrugs off grit and hard knocks, offering about double the horizontal impact resistance of a plain cylinder where a steel-ball guide might jam from contamination. With a non-rotating accuracy of ±0.06°, it keeps a clamp or plate square under off-centre loads. The Ø16 mm piston rod uses 1/8" ports, and stroke ends are damped by fixed TPU bumpers rather than an adjustable air cushion. The standard built-in magnet supports CS1 reed or DS1 electronic switches in the four body slots.

| Acting type | Double acting |
| Bearing | Brass sliding bearing |
| Port size | 1/8" |
| 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) |
| Cushion | Rubber bumper |

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-TCM32X25S Is Used
Robot Weld Cell Clamp
Clamping heavy steel frames in a robot weld cell; the 402 N thrust at 0.5 MPa holds the part securely while the brass bearing tolerates weld spatter and grit.
Welding Line Gate Stop
Halting a moving pallet on a transfer line; the twin guide rods absorb the horizontal side impact, protecting the cylinder from deflection.
Off-Centre Spot Weld Gun
Positioning a spot weld gun tip; the ±0.06° non-rotating tolerance keeps the electrode square against the workpiece under unbalanced radial loads.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X25S the Right Cylinder?
If you are sizing this cylinder, stepping down to a Ø25 bore yields roughly 245 N of push at 0.5 MPa, while stepping up to a Ø40 bore provides 628 N, letting you tune the clamp force to the job. Choose the sister TCL series instead if your weld fixture needs low-friction, high-precision vertical movement via its steel-ball linear bearing. Remember that this guided rod resists rotation, not gravity; the tool drops if air pressure is lost, so fit an external rod lock or pilot check valve for fail-safe holding. Replacement requires matching the 32 mm bore, 25 mm stroke, 1/8" PT thread, and 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-TCM32X25S FAQ
At 0.5 MPa it provides 402 N of push and 302 N of pull. At 0.7 MPa the push increases to 563 N, with a theoretical maximum force of 82 kgf.
The B02- prefix marks this as AirTAC's welding-industry dedicated variant of the TCM32X25S; it is mechanically identical to the base model. It uses fixed rubber TPU bumpers at each end to soften the stop, with no adjustable air cushion screw to set.
