Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X70S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X70S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 70mm 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-TCM32X70S
The AirTAC B02-TCM32X70S is a JIS-standard, double-acting twin-rod guided cylinder built for welding-line automation. The B02- prefix marks this as AirTAC's welding-industry dedicated variant of the base TCM32X70S, meaning it is mechanically identical to the standard unit but earmarked for fixturing and clamping in robot weld cells. 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 itself prevents rotation, you do not need to bolt on an external linear rail.
This 32 mm bore model uses a brass sliding bearing that shrugs off grit, dust and hard knocks, offering about double the horizontal impact resistance of a plain cylinder. That contamination tolerance is exactly why it suits weld cells where spatter would jam a steel-ball guide. Anti-rotation accuracy holds at ±0.06°, keeping a clamping plate square under off-centre loads. The Ø16 mm piston rod feeds via 1/8" ports, and stroke ends are damped by fixed TPU bumpers rather than an adjustable air cushion. The standard built-in magnet works with CS1 reed or DS1 electronic switches in the four body slots.

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-TCM32X70S Is Used
Spot Weld Cell Clamp
Delivers 402 N of clamping force at 0.5 MPa to hold panels in a robot spot-weld cell, where the brass sliding bearing tolerates weld spatter and grit that would destroy a ball guide.
Off-Centre Fixture Slide
Holds a fabrication part square against an off-centre load with a strict ±0.06° non-rotating tolerance, using the twin guide rods to absorb the resulting torque.
Weldment Gate Stop
Acts as a heavy-duty stop for moving weldment pallets, absorbing the horizontal impact via the impact-tolerant brass bearing instead of transferring the shock to the drive piston.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X70S the Right Cylinder?
When sizing this model, compare its 402 N push at 0.5 MPa against its neighbours: stepping down to a Ø25 bore yields roughly 245 N of thrust, while moving up to a Ø40 bore provides 628 N. Choose the sister TCL series instead if your task demands the low-friction, high-precision motion of a steel-ball linear bearing for vertical high-load work. To replace this unit, match the 32 mm bore, 70 mm stroke, 1/8" port, PT thread form, and standard S magnet. If air pressure drops or the valve centres, the rod will drift and drop, as the guide resists rotation rather than gravity; install an external pilot 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-TCM32X70S FAQ
This 32 mm bore cylinder generates 402 N of push and 302 N of pull at 0.5 MPa, and 563 N of push at 0.7 MPa, with a theoretical maximum force of 82 kgf. It operates on filtered air at 0.15-1.0 MPa, runs at 30-500 mm/s, and uses a fixed 1/8" port size.
The B02- prefix simply designates this as the welding-industry dedicated variant of the TCM32X70S; the physical specs, seals and materials remain identical to the base model. For end-of-stroke damping, it relies on fixed rubber TPU bumpers at each end, meaning there is no adjustable air cushion or cushion screw to set.
