Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X30S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X30S is a genuine JIS-standard guided cylinder with a Ø63mm bore and 30mm 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-TCM63X30S
The B02-TCM63X30S is AirTAC's welding-industry dedicated variant of the TCM63X30S, a JIS guided twin-rod double-acting cylinder. The 'B02-' prefix designates its role in welding-line automation without altering the base mechanics. A drive piston operates between two guide rods supported by a brass sliding bearing, which tolerates grit and weld spatter where a steel-ball guide would jam. Delivering 1559 N of push at 0.5 MPa, this 63 mm bore unit handles heavy clamping duty.
Anti-rotation accuracy holds at ±0.05°, keeping a fixture or clamp plate square under off-centre loads. The Ø20 mm piston rod uses 1/4" ports, and stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. The standard built-in magnet works with CS1 reed or DS1 electronic switches in the four body slots.

| Acting type | Double acting |
| Bearing | Brass sliding bearing |
| Port size | 1/4" |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Non-rotating tolerance | ±0.05° (retracted) |
| Cushion | Rubber bumper |
| Max std stroke | Up to 250 mm |
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-TCM63X30S Is Used
Robot Welding Cell Clamp
Secures heavy steel frames in a robot weld cell. The brass sliding bearing shrugs off spatter and debris while 1559 N of thrust at 0.5 MPa holds the part rigidly against the weld gun.
Weldment Transfer Stop
Halts palletized weldments on a transfer line. The twin guide rods absorb the radial impact of arriving loads, maintaining a ±0.05° non-rotating tolerance to keep the stop plate perfectly square.
Spot Weld Tip Dresser
Drives the cutter for spot weld tip maintenance. The integrated guide handles the side-load of the cut without needing an external rail, operating reliably in a gritty, high-knock environment.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X30S the Right Cylinder?
Select this 63 mm bore when a welding cell demands high impact resistance alongside 1559 N of thrust at 0.5 MPa. If you need less force, stepping down to a 50 mm bore yields 982 N of push; moving up to an 80 mm bore provides 2513 N. Choose the sibling TCL series with its steel-ball linear bearing instead only if your application requires extreme vertical precision and low friction rather than dirty-duty radial load tolerance.
To replace this unit, match the 63 mm bore, 30 mm stroke, 1/4" port size, and PT thread form, ensuring the standard magnet (S) is included. Note that a TC cylinder will drift and drop if air pressure is lost, so fit an external rod lock or pilot check valve for fail-safe load holding.
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-TCM63X30S FAQ
This 63 mm bore cylinder generates 1559 N of push and 1402 N of pull at 0.5 MPa. At 0.7 MPa, the push force increases to 2182 N. The theoretical maximum force is 318 kgf.
The B02- prefix marks this as AirTAC's welding-industry dedicated line; mechanically, it is identical to the standard TCM63X30S. It uses fixed rubber (TPU) bumpers at each end to soften the stroke stop, meaning there is no adjustable air cushion or cushion screw to set.
