Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X150S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X150S is a genuine JIS-standard guided cylinder with a Ø40mm 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 ±0.06° of rotation without any external linear guide.

About the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X150S
The AirTAC B02-TCM40X150S is a JIS guided twin-rod cylinder engineered for welding-line automation, mechanically identical to the standard TCM40X150S. The B02- prefix simply designates it as AirTAC's welding-industry dedicated variant. A drive piston runs between two guide rods in a single integrated body, completely removing the need for an external linear slide. Utilizing a robust brass sliding bearing, it shrugs off grit, weld spatter, and hard knocks, delivering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide would jam.
Delivering 628 N of push at 0.5 MPa, this double-acting unit handles substantial side loads and torque up to the datasheet limit for the chosen stroke. The Ø16 mm piston rod operates on 1/8" ports, while the twin-guide design holds a tight ±0.06° non-rotating tolerance, keeping clamps or plates perfectly square under off-centre loads. Stroke termination relies on fixed TPU bumpers rather than an adjustable air cushion. Two independent upper and side port groups allow pneumatic plumbing from whichever face is clear, and precision locating holes ensure you can swap the unit without re-teaching the fixture position.

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 B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X150S Is Used
Spot Welding Clamp
Holding an off-centre spot-welding gun steady against a car body panel. The brass sliding bearing tolerates spatter and debris, while the ±0.06° non-rotating accuracy keeps the electrode aligned under the 628 N push load.
Weld Cell Pallet Stop
Gating heavy pallets entering a robotic welding station. The twin guide rods absorb the radial impact of the arriving load, shrugging off the knocks that would damage a standard cylinder's rod seals.
Fixture Alignment Pin
Driving a locating pin into a heavy steel frame before the arc starts. The integrated guide prevents pin rotation and deflection, ensuring the frame seats perfectly without needing a separate linear rail.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X150S the Right Cylinder?
This 40 mm bore generates 628 N of thrust at 0.5 MPa. If you need less force, the Ø32 bore provides about 402 N; stepping up to the Ø50 bore yields 982 N. Choose the sister TCL series instead if your weld cell demands the low-friction, high-precision movement of a steel-ball linear bearing for vertical or heavy-load positioning. To replace this unit, match the 40 mm bore, 150 mm stroke, 1/8" PT ports, and the standard built-in magnet (S). Remember that a guided cylinder drifts if air pressure drops, so fit an external rod lock or pilot check valve if the fixture must stay put during an air loss event.
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-TCM40X150S 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, with a theoretical maximum force of 128 kgf. Operating pressure spans 0.15-1.0 MPa, and the piston speed ranges from 30-500 mm/s.
The B02- prefix marks this as AirTAC's welding-industry dedicated variant; it is mechanically identical to the TCM40X150S with no special seals or coatings. For end-of-stroke damping, it uses fixed rubber TPU bumpers at both ends—there is no adjustable air cushion screw to set.
