Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL63X25S
The AirTAC Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL63X25S is a genuine JIS-standard guided cylinder with a Ø63mm bore and 25mm 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 ±0.04° of rotation without any external linear guide.

About the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL63X25S
The B02-TCL63X25S is an AirTAC 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 base TCL63X25S, built identically for fixturing and clamping in robot welding cells. It delivers a substantial 1559 N of push and 1402 N of pull at 0.5 MPa, making it suited to heavy-duty part manipulation. A drive piston operates between two guide rods in a single integrated body, completely removing the need for an external linear slide.
The integrated twin-rod mechanism yields a non-rotating accuracy of ±0.04°, keeping fixtures or grippers perfectly square under offset loads. Its steel-ball linear bearing ensures low-friction, stick-slip-free travel, which is critical for smooth vertical lifts and high-cycle positioning. Air is plumbed via 1/4" ports feeding a Ø20 mm piston rod. Stroke terminations rely on fixed TPU bumpers rather than adjustable air cushions. Note that the guide prevents rotation but will not stop the rod from drifting downward if air pressure is lost; fit an external rod lock for fail-safe vertical holding.

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 (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1402 N |
| 0.7 MPa | 2182 N | — |
| Max | 318 kgf | |
Force is set by the bore and piston rod (Ø20 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-TCL63X25S Is Used
Robot Welding Cell Clamping
Harnessing 1559 N of clamping force at 0.5 MPa, this cylinder secures heavy steel assemblies. The ±0.04° non-rotating tolerance ensures the clamp face stays parallel to the weld seam during automated robot sequences.
Spot Welder Tip Dressing
The steel-ball linear bearing provides the low-friction vertical travel needed to lower heavy welding heads without stick-slip, ensuring repeatable positioning over thousands of maintenance cycles.
Welded Pallet Stopper Gate
With 2182 N of push available at 0.7 MPa, this unit halts heavy loaded pallets entering a welding booth. The integrated guide rods absorb the side impact of the moving load without needing an external shock absorber.
Is the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL63X25S the Right Cylinder?
Selecting this 63 mm bore provides 1559 N of thrust at 0.5 MPa. If your welding fixture requires less force, stepping down to the Ø50 bore yields roughly 982 N of push. Conversely, moving up to the Ø80 bore provides 2513 N for heavier stamping or clamping duties. For welding environments with heavy impact loads or high abrasive dust, consider the sister TCM63 series, which uses a brass sliding bearing instead of the linear ball bearing to better absorb radial shocks. To order a replacement, specify the 63 mm bore, 25 mm stroke, 1/4" port size, PT thread form, 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-TCL63X25S FAQ
At 0.5 MPa it generates 1559 N of push and 1402 N of pull. At 0.7 MPa the push force increases to 2182 N. The theoretical maximum force is 318 kgf at 1.0 MPa. The operating speed ranges from 30-500 mm/s.
The B02- prefix marks this as the welding-industry dedicated variant of the TCL63X25S; mechanically it shares the exact same specs as the base model. It uses fixed rubber TPU bumpers at each end to soften the stop, meaning there is no adjustable air cushion or cushion screw to set. It also includes a standard magnet for CS1 reed or DS1 electronic switches.
