Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X75S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X75S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 75mm 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-TCM32X75S
The AirTAC B02-TCM32X75S is a JIS-standard twin-rod guided cylinder engineered for welding-line automation. The leading "B02-" prefix designates this as a welding-industry dedicated variant of the base TCM32X75S, meaning it shares the exact same physical specs while being targeted at robotic spot welding and clamping cells. A drive piston operates between two guide rods in a single integrated body, eliminating the need for an external linear rail. Delivering 402 N of push at 0.5 MPa, this double-acting actuator handles substantial mid-range work. Its brass sliding bearing shrugs off grit, coolant, and hard knocks—offering roughly double the horizontal impact resistance of a plain cylinder where a steel-ball guide would jam from contamination.
Precision is maintained under off-centre loads thanks to a tight non-rotating tolerance of ±0.06°, keeping fixtures square during dynamic positioning. The Ø16 mm piston rod is driven via 1/8" ports, while two independent upper and side port groups let you route air from whichever face is clear without extra elbows. Stroke termination relies on fixed TPU bumpers at each end to soften the impact, as there is no adjustable air cushion screw to tune. Four sensor slots accommodate CS1 reed or DS1 electronic switches to read 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-TCM32X75S Is Used
Spot Welding Cell Clamp
Holding heavy steel stampings in a robotic spot-welding cell; the brass sliding bearing tolerates weld spatter and grit where a ball guide would seize, while 402 N of push secures the part.
Off-Centre Gripper Slide
Actuating an offset gripper to load chassis components; the ±0.06° non-rotating accuracy keeps the jaws square under torsional load without needing a separate external guide rail.
Weldment Pallet Stop
Gating pallets of raw forgings into a weld fixture; the twin guide rods absorb the horizontal impact of the arriving load, surviving knocks that would damage a standard round-body cylinder.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X75S the Right Cylinder?
Selecting this 32 mm bore yields 402 N of thrust at 0.5 MPa. If your fixturing requires less force, stepping down to the Ø25 model provides roughly 245 N of push; conversely, moving up to the Ø40 bore supplies about 628 N for heavier weldment clamping. When replacing this unit, match the 32 mm bore, 75 mm stroke, 1/8" port, PT thread form, and the standard S magnet. Choose the sister TCL series with its steel-ball linear bearing instead only if your application demands low-friction, high-precision vertical movement rather than dirty, impact-heavy radial loading. Note that a TC guide resists rotation, not gravity; the rod will drift downward if air pressure is lost or the valve is centred, so fit an external rod lock or pilot-operated check valve for fail-safe load holding.
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-TCM32X75S 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 increases to 563 N, with a theoretical maximum force of 82 kgf. Operating pressure ranges from 0.15 to 1.0 MPa, and the piston speed spans 30-500 mm/s.
The B02- prefix indicates this is AirTAC's welding-industry dedicated variant of the TCM32X75S, mechanically identical to the base model. Stroke ends are damped by fixed elastomer TPU pads rather than an adjustable air cushion, meaning there is no cushion screw to adjust. The standard built-in magnet works with CS1 reed or DS1 electronic switches in the four body slots.
