The AirTAC Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X25S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 25mm 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.
The B02-TCL50X25S is an AirTAC JIS guided twin-rod double-acting cylinder featuring a steel-ball linear bearing. The B02- prefix designates this as a welding-industry dedicated variant, mechanically identical to the standard TCL50X25S, making it ideal for clamping and fixturing in automated welding cells. Driven by a 50mm bore, it generates 982N of push and 825N of pull at 0.5MPa. The integrated twin guide rods eliminate the need to align an external linear rail, saving engineering time.
A standout feature is the steel-ball linear bearing, which provides low-friction, high-precision travel without the stick-slip common to plain bearings, ensuring smooth vertical lifts. With a non-rotating tolerance of ±0.04°, it keeps fixtures square under off-centre loads. The Ø20mm piston rod operates on 1/4" ports, while dual upper and side port groups allow pneumatic plumbing from the most accessible angle. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion.

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 | 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.
| TC | Tri-rod (guided, twin-rod) cylinder, double acting. |

| L | Bearing: Steel-ball linear bearing (L = linear ball). |
| 50 | Bore size in mm. |
| ×25 | Stroke length in mm. |
| S | Built-in magnet (standard on TC) for a magnetic sensor switch. |
Sister type: TCM50X25 (brass sliding bearing, more impact/dust tolerant). Thread codes: blank = PT · G · T = NPT.
Leveraging the 982N push at 0.5MPa and the low-friction linear bearing, this cylinder smoothly positions heavy spot-welding tips without stick-slip, ensuring precise electrode alignment.
The ±0.04° non-rotating tolerance keeps clamping jaws perfectly square on off-centre workpieces, while the twin-rod guide absorbs the side torque generated during part fixturing.
With its integrated guide replacing external rails, this unit saves space in tight robotic cells, delivering 1374N of thrust at 0.7MPa to gate or position heavy pallets.
When sizing this 50mm bore model, consider stepping down to a Ø32 cylinder for lighter duties, which provides about 402N of push at 0.5MPa, or moving up to a Ø63 bore that yields 1559N if your fixture demands more clamping force. Choose the TCM sibling series instead if your application involves heavy impact loads or dusty environments, as its brass sliding bearing handles radial abuse better than the precision steel-ball bearing. For replacement, match the 50mm bore, 25mm stroke, 1/4" port, PT thread, and standard S magnet. Note that air pressure loss will cause the rod to drift downward, as the guide resists rotation but not gravity; install an external rod lock for fail-safe holding.
Quick checklist
This 50mm bore cylinder delivers 982N push and 825N pull at 0.5MPa, 1374N push at 0.7MPa, and a maximum theoretical force of 200kgf. It operates at speeds of 30-500mm/s.
The B02- prefix indicates this is AirTAC's welding-industry dedicated variant of the TCL50X25S, sharing identical mechanical specs. Instead of an adjustable air cushion, each end lands on a fixed TPU rubber bumper to soften the stop.
