Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X30S
The AirTAC Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X30S is a genuine JIS-standard guided cylinder with a Ø40mm bore and 30mm stroke on twin guide rods. Its integrated steel-ball linear bearing gives low-friction, high-precision travel — well suited to vertical lifts and high-load, high-accuracy moves, holding the tool square to ±0.05° of rotation without any external linear guide.

About the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X30S
The B02-TCL40X30S is AirTAC's welding-industry dedicated variant of the TCL40X30S, mechanically identical to the base JIS guided twin-rod cylinder. The B02- prefix simply designates its application focus for welding-line automation, retaining the exact same physical specifications. A drive piston operates between two guide rods integrated into one body, utilizing a steel-ball linear bearing for low-friction, high-precision travel. This design entirely eliminates the need for an external linear guide. Delivering 628 N of push at 0.5 MPa, this double-acting unit handles substantial loads with smooth, stick-slip-free vertical motion.
Precision is critical in fixturing, and this model holds a ±0.05° non-rotating tolerance, keeping clamps or plates perfectly square under off-centre loads. It features a Ø16 mm piston rod and 1/8" ports. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, absorbing impact without requiring tuning. The integrated body includes precision locating holes, allowing you to remove and re-fit the unit without re-teaching the position. Four sensor slots accept CS1 reed or DS1 electronic switches to track 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 (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-TCL Welding Special Triple-Axis Cylinder B02-TCL40X30S Is Used
Spot Welding Clamp Actuation
Provides 628 N of thrust at 0.5 MPa to close welding clamps. The steel-ball linear bearing ensures smooth, low-friction travel with no stick-slip, while the ±0.05° non-rotating accuracy keeps the clamp jaws perfectly aligned during the weld cycle.
Welding Line Pallet Stop
Acts as a heavy gate stop for pallets entering a robot welding cell. The twin guide rods absorb the radial impact and side load of the moving pallet, protecting the internal drive piston from deflection.
Off-Centre Fixture Positioning
Lifts and locates uneven weldments with an off-centre gripper. The integrated guide unit handles the resulting torque up to the datasheet limit for this stroke, maintaining precise vertical positioning without needing a separate rail.
Is the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X30S the Right Cylinder?
When sizing this 40 mm bore, consider moving a step in either direction: the Ø32 bore yields roughly 402 N of push, while the Ø50 bore provides about 982 N at 0.5 MPa. Choose the TCL steel-ball linear bearing for high-precision, smooth vertical lifts; if your welding cell involves heavy impact loads or dusty radial-load duty, the sister TCM series with its brass sliding bearing is the better choice. Remember that the guide resists rotation, not gravity—air pressure loss will cause the rod to drift, so install an external rod lock or pilot-operated check valve for fail-safe holding. Replacement matches require a 40 mm bore, 30 mm stroke, 1/8" port, PT thread, and the 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-TCL Welding Special Triple-Axis Cylinder B02-TCL40X30S FAQ
At 0.5 MPa, this double-acting cylinder generates 628 N of push and 528 N of pull. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
The B02- prefix marks this as AirTAC's welding-industry dedicated variant of the TCL40X30S, meaning it is mechanically identical to the base model. Each end lands on a fixed TPU bumper that softens the stop; there is no air-cushion screw to set. The standard built-in magnet works with CS1 reed or DS1 electronic switches.
