The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM63X40S is a genuine JIS-standard guided cylinder with a Ø63mm bore and 40mm 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.
The B02-TCM63X40S is AirTAC's welding-industry dedicated variant of the TCM63X40S, engineered for clamping and fixturing in automated weld cells. Mechanically identical to the base model, it is a JIS twin-rod guided cylinder featuring a brass sliding bearing. The dual guide rods and integrated body eliminate the need for an external linear rail, absorbing spatter and hard knocks where a steel-ball bearing would jam. Delivering 1559 N of push at 0.5 MPa, this double-acting actuator easily handles heavy off-centre loads.
A Ø20 mm piston rod drives the tooling, fed by 1/4" ports. The brass sleeve design provides roughly double the horizontal impact resistance of a plain cylinder, ensuring durability in demanding robotic spot-welding environments. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion. With a non-rotating accuracy of ±0.05°, your gripper or clamp plate stays perfectly square under severe eccentric forces during the weld cycle.

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.
| 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.

Sister type: TCL63X40 (steel-ball linear bearing, lower friction & higher precision). Thread codes: blank = PT · G · T = NPT.
Tolerates weld spatter and grit where a ball guide would jam. The 1559 N push at 0.5 MPa securely clamps heavy steel panels, while the brass sliding bearing absorbs the mechanical shock of the gun closing.
Holding a heavy locater pin block square against an off-centre workpiece. The ±0.05° non-rotating tolerance ensures the fixture plate does not twist under eccentric load, maintaining precise part alignment.
Halting a loaded pallet entering a weld assembly line. The twin guide rods carry the severe radial impact of the moving load, protecting the internal Ø20 mm piston rod from bending forces.
Selecting this 63 mm bore provides 1559 N of thrust at 0.5 MPa. If you need less clamping force, stepping down to a Ø50 bore yields 982 N of push; conversely, moving up to a Ø80 bore provides 2513 N for heavier fixturing. The standard built-in magnet (S) enables position feedback via CS1 reed or DS1 electronic switches in the four body slots. Thread form defaults to PT.
Because the brass guide resists rotation but not gravity, the rod will drift downward if air pressure is lost or the valve is centred; fit an external pilot-operated check valve if the weld fixture must stay clamped during an emergency stop. The sibling TCL series uses a steel-ball linear bearing, which is preferable for low-friction, high-precision vertical lifting, whereas this TCM excels in dirty, high-impact radial-load duty.
Quick checklist
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 maximum theoretical force is 318 kgf.
The B02- prefix designates this as AirTAC's welding-industry dedicated line of the TCM63X40S; mechanically, every spec matches the base cylinder exactly. There is no adjustable air cushion; instead, a fixed rubber TPU bumper at each end softens the end-of-stroke impact.
