Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X90S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X90S is a genuine JIS-standard guided cylinder with a Ø63mm bore and 90mm 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-TCM63X90S
The B02-TCM63X90S is AirTAC's welding-industry dedicated variant of the TCM63X90S, engineered specifically for fixturing and clamping in automated weld cells. The B02- prefix designates this application focus without altering the core mechanics: it remains a JIS-standard twin-rod guided cylinder featuring a rugged brass sliding bearing. Because the drive piston runs between two integrated guide rods, you get a self-contained unit that carries heavy radial loads and torque without needing an external linear rail. Delivering 1559 N of push at 0.5 MPa, it easily handles heavy part manipulation.
The brass sliding bearing is the key advantage in a gritty weld-cell environment, shrugging off dust and spatter where a steel-ball linear guide would jam or wear prematurely. It provides approximately double the horizontal impact resistance of a plain cylinder. Anti-rotation precision is held to ±0.05°, keeping a heavy fixture plate perfectly square under off-centre loads. Plumbing is simplified by dual independent port groups (upper face and side) on 1/4" ports, while the Ø20 mm piston rod drives the load. Stroke termination relies on fixed TPU rubber bumpers at each end to soften the impact, as no adjustable air cushion is featured on this series.

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-TCM63X90S Is Used
Robot Welding Cell Clamp
Holds heavy chassis sub-assemblies square against the weld table. The brass sliding bearing tolerates weld spatter and grinding dust, maintaining its 1559 N clamping force where a linear ball guide would seize.
Spot Weld Gun Actuation
Drives the lower electrode arm with ±0.05° non-rotating accuracy to ensure perfect tip alignment. The twin-rod body absorbs the intense mechanical shock of the weld nugget formation without an external guide rail.
Hot Panel Transfer Stop
Functions as a heavy-duty gating stop on a cooling line. The integrated guide rods endure the repeated side-impact of incoming pallets, while the Ø20 piston rod cycles reliably at speeds up to 500 mm/s.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X90S the Right Cylinder?
When sizing this model, compare its 1559 N push (at 0.5 MPa) against adjacent bores: stepping down to a Ø50 yields roughly 982 N, while moving up to a Ø80 provides 2513 N, letting you tune the clamp force to the exact fixture weight. Choose the sister TCL series instead if your task demands ultra-low friction or high-precision vertical lifting, as the TCL utilizes a steel-ball linear bearing. Remember that a guided cylinder resists rotation, not gravity; if air pressure drops or the valve is centred, the rod will drift, so fit an external pilot check valve for fail-safe load holding. Replacement requires matching the 63 mm bore, 90 mm stroke, 1/4" port, 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-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X90S FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push and 1402 N of pull. At the maximum operating pressure of 1.0 MPa, it delivers 2182 N of push. The theoretical maximum force is 318 kgf.
The B02- prefix simply marks this as AirTAC's welding-industry dedicated variant of the base TCM63X90S; it is mechanically identical to the standard model. It does not have adjustable air cushions; instead, fixed TPU rubber bumpers at each end absorb the end-of-stroke impact.
