Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X200S
The AirTAC B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X200S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 200mm 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-TCM50X200S
The B02-TCM50X200S is AirTAC's welding-industry dedicated variant of the TCM50X200S, mechanically identical to the base JIS guided twin-rod cylinder. A drive piston operates between two guide rods supported by a brass sliding bearing within a single integrated body. This configuration yields roughly 982 N of push at 0.5 MPa while maintaining a non-rotating accuracy of ±0.05°, keeping fixtures square under offset loads without needing an external linear rail.
Designed for weld-cell automation, the brass sliding bearing tolerates hard knocks and shrugs off grit or spatter where a steel-ball guide might jam. The Ø20 mm piston rod uses 1/4" ports, and two independent port groups let you feed air from the top face or side. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, and the standard built-in magnet works with CS1 reed or DS1 electronic switches in any of the four sensor slots.

| 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) |

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-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X200S Is Used
Spot Welding Gun Clamp
Applies 982 N of clamping force at 0.5 MPa to hold panels. The brass sliding bearing resists weld spatter and grit, maintaining the ±0.05° non-rotating tolerance to keep electrodes perfectly aligned.
Welding Line Pallet Stop
Halts heavy pallets on a robotic fusion line. The twin guide rods absorb the radial impact of arriving loads, functioning reliably in dirty environments where a linear ball bearing would fail.
Off-centre Robot Fixture
Pushes an offset gripper carrying a heavy chassis subassembly. The integrated guide handles the torque without an external rail, while the 1/4" port feeds the 982 N push force needed to seat the part.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X200S the Right Cylinder?
This 50 mm bore delivers 982 N of thrust at 0.5 MPa. If you need less force, stepping down to a Ø40 bore yields about 628 N; moving up to a Ø63 bore provides 1559 N. Choose the sister TCL series with its steel-ball linear bearing instead if your fixture demands ultra-low friction or high-precision vertical loading. Remember that air pressure drives both extension and retraction, so the rod will drift if supply is lost—add an external rod lock for fail-safe holding. Replacement requires a 50 mm bore, 200 mm stroke, 1/4" port with PT thread, 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-TCM50X200S FAQ
At 0.5 MPa this 50 mm bore cylinder generates 982 N of push and 825 N of pull. At 0.7 MPa the push increases to 1374 N. The theoretical maximum force is 200 kgf.
The B02- prefix simply marks this as AirTAC's welding-industry dedicated variant of the TCM50X200S; the physical specs, seals, and materials are identical to the base model. It uses fixed rubber TPU bumpers at each end to soften the stop, meaning there is no adjustable air cushion screw to set.
