Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X200S
The AirTAC Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X200S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 200mm 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.

About the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X200S
The AirTAC B02-TCL50X200S is a JIS guided twin-rod double-acting cylinder equipped with a steel-ball linear bearing. The B02- prefix designates this as a welding-industry dedicated variant of the base TCL50X200S, mechanically identical to the standard unit and purpose-built for welding-line automation. It delivers 982 N of push and 825 N of pull at 0.5 MPa, utilizing a Ø20 mm piston rod and 1/4 inch ports. The integrated twin guide rods completely replace an external linear slide, saving valuable space and eliminating the alignment work of matching a separate rail to a cylinder.
Because the guide rods use a steel-ball linear bearing, travel is highly precise with no stick-slip, making it exceptionally well-suited for vertical lifts and high-cycle loads. The unit holds a non-rotating tolerance of ±0.04°, keeping a gripper or clamping plate perfectly square under an off-centre load. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, absorbing the stop at both ends without requiring any air-cushion screw adjustments. Two independent port groups (upper face and side) let you feed air from whichever side is free without extra elbows, and precision locating holes ensure you can re-fit the cylinder without re-teaching the position.

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 (Ø50mm)
| 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.

Where the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X200S Is Used
Robot Welding Clamp
Actuates an off-centre gripper in a spot-welding cell, using the 982 N push at 0.5 MPa and ±0.04° non-rotating tolerance to hold panels square during the weld.
Welding Fixture Vertical Lift
Lowers a heavy tool carriage on a welding line; the steel-ball linear bearing ensures smooth, stick-slip-free vertical travel across the 200 mm stroke.
Pallet Gate Stop
Halts heavy pallets feeding into a robotic welder, absorbing the side load on the twin guide rods while the Ø20 mm piston rod delivers the stopping force.
Is the Airtac B02-TCL Welding Special Triple-Axis Cylinder B02-TCL50X200S the Right Cylinder?
When sizing this 50 mm bore, consider stepping down or up based on your force needs. The neighbouring Ø32 bore gives roughly 402 N of push at 0.5 MPa, while the larger Ø63 bore provides 1559 N. If your application involves heavy impact loads or dusty environments rather than precision lifting, the sister TCM series with its brass sliding bearing is the better choice. To replace this unit, match the 50 mm bore, 200 mm stroke, 1/4 inch port, PT thread form, and standard S magnet. Note that a TC does not hold its load if air pressure is lost; the rod drifts, so for a fail-safe hold you must add an external rod lock or pilot check valve.
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-TCL Welding Special Triple-Axis Cylinder B02-TCL50X200S FAQ
This 50 mm bore cylinder generates 982 N of push and 825 N of pull at 0.5 MPa, 1374 N of push at 0.7 MPa, and a maximum theoretical force of 200 kgf. It operates at a speed of 30-500 mm/s.
The B02- prefix marks this as AirTAC's welding-industry dedicated variant of the TCL50X200S, mechanically identical to the base model. Each end lands on a fixed TPU bumper; there is no adjustable air cushion or cushion screw to set.
