Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X250S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X250S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 250mm 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-TCM32X250S
The AirTAC B02-TCM32X250S is a JIS-standard twin-rod guided cylinder engineered for welding-line automation. The B02- prefix designates this as a welding-industry dedicated variant, mechanically identical to the standard TCM32X250S. A drive piston operates between two guide rods in a single integrated body, completely eliminating the need for an external linear slide. Double-acting air drives the Ø16 mm piston rod, delivering 402 N of push at 0.5 MPa. Brass sliding bearings support the rods, shrugging off grit and weld spatter where a steel-ball guide would jam.
This 32 mm bore model achieves a non-rotating accuracy of ±0.06°, keeping clamps and fixtures square under off-centre loads. Operating at 30-500 mm/s, the cylinder provides 250 mm of travel. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. Two independent port groups (upper face and side) on the 1/8" ports let you route pneumatic lines from whichever side is clear, while four sensor slots accept CS1 reed or DS1 electronic switches via the standard built-in magnet.

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-TCM32X250S Is Used
Robot Welding Cell Clamp
Secures heavy steel frames in a robot welding cell. The brass sliding bearing tolerates weld spatter and dust, delivering 402 N of clamping force while maintaining ±0.06° alignment against off-centre loads.
Welding Line Pallet Stop
Halts pallets carrying raw assemblies on a transfer line. The twin-rod design absorbs the horizontal impact of arriving loads—about double the resistance of a plain cylinder—without bending the Ø16 mm piston rod.
Spot Weld Gun Actuator
Positions a spot weld gun tip onto sheet metal parts. The integrated guide removes the need for a separate rail, saving space in tight robotic arms, while the 1/8" ports allow flexible hose routing.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X250S the Right Cylinder?
Selecting this 32 mm bore yields 402 N push and 302 N pull at 0.5 MPa. If you need less force, the Ø25 model provides roughly 245 N of thrust; stepping up to the Ø40 bore gives about 628 N. For welding fixtures requiring extreme vertical precision or low-friction movement, consider the sister TCL series with its steel-ball linear bearing instead of this brass sliding version. Remember that a TC guide resists rotation, not gravity: if air pressure drops, the rod drifts, so fit an external rod lock or pilot check valve for fail-safe holding.
This SKU uses PT (tapered) ports by default and includes the standard S magnet. The 250 mm stroke sits right at the maximum standard limit for this bore. To replace it, specify bore 32, stroke 250, 1/8" port, PT thread, and the 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-TCM32X250S FAQ
At 0.5 MPa, this 32 mm bore cylinder generates 402 N of push and 302 N of pull. At 0.7 MPa, the push force increases to 563 N. The theoretical maximum force is 82 kgf.
The B02- prefix indicates this is an AirTAC welding-industry dedicated variant of the TCM32X250S; the physical specs, seals, and materials are identical to the base model. Each end lands on a fixed TPU bumper to soften the stop—there is no air-cushion screw to set or adjust.
