Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X100S
The AirTAC Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X100S is a genuine JIS-standard guided cylinder with a Ø40mm bore and 100mm 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-TCL40X100S
The AirTAC B02-TCL40X100S is a JIS guided twin-rod double-acting cylinder featuring a steel-ball linear bearing. The leading "B02-" prefix designates this as the welding-industry dedicated variant of the TCL40X100S, meaning it is mechanically identical to the base model but tailored for welding-line automation fixturing and clamping. A central drive piston runs between two guide rods in a single integrated body, generating 628 N of push and 528 N of pull at 0.5 MPa. This architecture eliminates the need for an external linear slide, saving space and alignment effort.
Because the twin guide rods carry the torque and side load, the unit achieves a tight non-rotating tolerance of ±0.05°, keeping a fixture or clamping plate perfectly square under off-centre loads. The steel-ball linear bearing ensures low-friction, high-precision travel with no stick-slip, making it ideal for smooth vertical lifts in robotic cells. Air is plumbed via 1/8" ports, and the Ø16 piston rod handles the thrust. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, and the standard built-in magnet supports position sensing.

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-TCL40X100S Is Used
Spot Welding Gun Actuation
Leverages the 628 N push at 0.5 MPa to move the lower electrode arm. The ±0.05° non-rotating accuracy ensures the tips align perfectly every cycle, while the low-friction steel-ball bearing prevents stick-slip during high-speed approach.
Welding Fixture Clamping
Holds structural plates in a robotic welding cell. The twin-rod guide absorbs the offset torque from the clamping arm, removing the need for a separate external rail and simplifying the fixture design.
Vertical Assembly Press
Uses the smooth linear bearing to lower a component into a housing without binding. The fixed TPU bumpers soften the end of stroke, and the 880 N thrust at 0.7 MPa seats the part reliably.
Is the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL40X100S the Right Cylinder?
When sizing this model, consider stepping to a neighbouring bore: an Ø32 bore provides roughly 402 N of push at 0.5 MPa, while an Ø50 bore yields about 982 N, allowing you to adjust force capacity up or down as your fixturing payload demands. Choose the sister TCM series with its brass sliding bearing instead of this linear ball bearing if your application involves severe impact loads or heavily dusty radial-load environments. To replace this unit, match the 40 mm bore, 100 mm stroke, 1/8" port, PT thread form, and the standard S magnet.
Note that a TC cylinder does not hold its load if air pressure is lost or the valve is centred—the rod will drift, as the guide resists rotation, not gravity. For a fail-safe hold on a vertical welding fixture, incorporate an external rod lock or a pilot-operated check valve. Since the 100 mm stroke falls within the 250 mm maximum standard stroke for this bore, it is a stock configuration.
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-TCL40X100S FAQ
At 0.5 MPa, this 40 mm bore 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 simply marks this as AirTAC's welding-industry dedicated variant of the TCL40X100S; it shares the exact same physical specs as the base model. Regarding end-of-stroke damping, each end lands on a fixed TPU bumper—there is no adjustable air cushion screw to set. The standard built-in magnet works with CS1 reed or DS1 electronic switches in the four sensor slots.
