Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X80S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X80S is a genuine JIS-standard guided cylinder with a Ø63mm bore and 80mm 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 ±0.05° of rotation without any external linear guide.

About the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X80S
The B02-TCM63X80S is AirTAC's welding-industry dedicated variant of the TCM63X80S, mechanically identical to the base JIS guided twin-rod cylinder. A central drive piston runs between two guide rods supported by a brass sliding bearing, integrating the drive and anti-rotation guide into one body. This construction eliminates the need to align a separate cylinder to an external linear rail. Delivering 1559 N of push at 0.5 MPa, it carries heavy off-centre loads with a non-rotating accuracy of ±0.05°.
The brass sliding bearing is specifically advantageous in weld cells, shrugging off grit and hard mechanical knocks where a steel-ball linear guide would wear or jam. It provides roughly double the horizontal impact resistance of a plain cylinder. Stroke terminations are absorbed by fixed rubber TPU bumpers, as no adjustable air cushion is featured. The standard built-in magnet enables position feedback, and the 1/4" ports can be plumbed from either the upper face or side without extra elbows.

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-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X80S Is Used
Spot Welding Gun Clamp
Tolerates weld spatter and grit where a ball guide would jam, using its 1559 N thrust to hold heavy frame members square during the spot welding cycle.
Robotic Fixture Positioning
Maintains ±0.05° non-rotating accuracy on an off-centre gripper, leveraging the brass sliding bearing to absorb side-load impacts when loading heavy steel parts.
Welding Line Pallet Stop
Halts moving pallets carrying fabricated assemblies, using the twin guide rods to withstand the radial shock that would bend a standard plain cylinder rod.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X80S the Right Cylinder?
When sizing this 63 mm bore, stepping down to a 50 mm bore yields roughly 982 N of push at 0.5 MPa, while moving up to an 80 mm bore provides 2513 N. Choose this model when your weld-cell fixturing demands high radial load tolerance alongside 1559 N of thrust. If the application instead requires low-friction precision for vertical lifting, the sister TCL series with its steel-ball linear bearing is the better option. To replace this unit, match the 63 mm bore, 80 mm stroke, 1/4" PT ports, and the standard S magnet.
Note that a TCM guide prevents rotation but does not resist gravity; if air pressure drops or the valve is centred, the rod will drift. For fail-safe clamping in robotic welding, install an external rod lock or a pilot-operated check valve. The 80 mm stroke is well within the 250 mm standard maximum, so no made-to-order wait is required.
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-TCM63X80S FAQ
This 63 mm bore cylinder generates 1559 N push and 1402 N pull at 0.5 MPa, reaching 2182 N push at 0.7 MPa, with a theoretical maximum force of 318 kgf. It operates on filtered air at 0.15-1.0 MPa, runs at 30-500 mm/s, and uses a Ø20 mm piston rod with 1/4" ports.
The B02- prefix designates this as AirTAC's welding-industry dedicated line of the TCM63X80S; mechanically, every spec matches the base cylinder exactly. For end-of-stroke damping, it relies on fixed rubber TPU bumpers at each end. There is no adjustable air cushion or cushion screw to set.
