Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X150S
The AirTAC Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X150S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 150mm 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-TCL50X150S
The B02-TCL50X150S is AirTAC's welding-industry dedicated variant of the TCL50X150S, engineered for fixturing and clamping in automated welding cells. The leading B02- prefix denotes this specific application designation without altering the base mechanics. It is a JIS guided twin-rod double-acting cylinder where a central drive piston runs between two guide rods in a single integrated body. Because the guide unit itself prevents rotation and absorbs side loads, you can skip mounting an external linear rail. Delivering 982 N of push at 0.5 MPa, it carries substantial weight while holding a tight ±0.04° non-rotating tolerance.
This model relies on a steel-ball linear bearing that ensures low-friction, high-precision travel with absolutely no stick-slip, making it exceptionally well-suited for smooth vertical lifts and high-cycle positioning. The Ø20 mm piston rod operates on 1/4" ports, giving you robust flow for rapid actuation across the 150 mm stroke. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, simplifying setup. Four sensor slots accommodate CS1 reed or DS1 electronic switches to track position from any face, while the integrated magnet comes as a standard feature.

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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max | 200 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-TCL50X150S Is Used
Spot Welding Gun Actuation
Leveraging the 982 N push force and ±0.04° anti-rotation tolerance, this cylinder positions heavy spot-welding tips accurately on automotive frames without stick-slip, ensuring consistent weld nuggets.
Welding Fixture Clamping
The twin guide rods support off-centre clamping forces on curved metal workpieces, holding parts square while the steel-ball linear bearing maintains smooth operation through thousands of clamp cycles.
Vertical Electrode Lowering
Ideal for lowering heavy electrode assemblies; the low-friction linear bearing prevents gravity-induced drift on the way down, while the 150 mm stroke provides ample reach into the weld cell.
Is the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X150S the Right Cylinder?
When sizing this unit, compare its 982 N thrust at 0.5 MPa against neighboring bores to ensure you have the right capacity. Dropping down to a Ø32 bore yields about 402 N of push, whereas stepping up to a Ø63 bore provides 1559 N, letting you shift a step in either direction based on your actual load. If your welding cell involves heavy impact loads or high dust contamination, consider the sister TCM series instead, as its brass sliding bearing handles abusive radial loads better than the precision steel-ball bearing found here. To secure the load safely during a pneumatic failure, install an external rod lock or pilot-operated check valve, as the guide resists rotation but cannot prevent the rod from dropping if air pressure is lost. Replacement requires matching the 50 mm bore, 150 mm stroke, 1/4" port, PT thread form, and 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-TCL50X150S FAQ
At 0.5 MPa, this 50 mm bore cylinder provides 982 N of push and 825 N of pull. Increasing the pressure to 0.7 MPa raises the push force to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
The B02- prefix indicates this is AirTAC's welding-industry dedicated line of the TCL50X150S, mechanically identical to the base model for welding cell automation. It features fixed rubber TPU bumpers at each end to soften the stroke stop; it does not have an adjustable air cushion or cushion screw.
