Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X80S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X80S is a genuine JIS-standard guided cylinder with a Ø50mm bore and 80mm 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-TCM50X80S
The B02-TCM50X80S is AirTAC's welding-industry dedicated variant of the standard TCM50X80S, meaning the B02- prefix simply designates its factory alignment with welding-line automation rather than altering any base mechanics. It is a JIS guided twin-rod double-acting cylinder where a central drive piston runs between two guide rods in a single integrated body. Because the guide unit itself prevents rotation and absorbs side load, you can skip mounting an external linear rail. The brass sliding bearing is specifically chosen for dirty, high-impact environments, shrugging off grit and hard knocks that would jam a steel-ball guide. Delivering 982 N of push at 0.5 MPa, this 50 mm bore unit handles heavy fixturing tasks with ease.
Precision is tightly controlled, offering a ±0.05° non-rotating tolerance that keeps a clamping plate perfectly square under an off-centre load. The Ø20 mm piston rod is fed by 1/4" ports, and you can plumb from either the upper face or side port groups without needing elbow fittings. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, absorbing the shock of heavy weldments. The standard built-in magnet supports CS1 reed or DS1 electronic switches across four sensor slots, while the brass bearing provides roughly double the horizontal impact resistance of a plain cylinder for rugged weld-cell duty.

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-TCM50X80S Is Used
Robot Welding Cell Clamp
Holds heavy steel frames square for a robot torch, using its 982 N thrust at 0.5 MPa while the brass sliding bearing tolerates weld spatter and grinding dust that would destroy a ball guide.
Weldment Transfer Stop
Acts as a rugged pallet stop on a transfer line, absorbing the horizontal impact of arriving loads at double the resistance of a plain cylinder without bending the Ø20 rod.
Off-Centre Spot Weld Gun
Maintains ±0.05° non-rotating accuracy on an offset spot-welding tip, keeping the electrodes aligned despite the twisting moment generated during the squeeze cycle.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM50X80S the Right Cylinder?
When sizing this model, stepping down to a Ø40 bore yields about 628 N of push at 0.5 MPa, whereas stepping up to a Ø63 bore provides 1559 N. Choose this 50 mm option when your weld fixture demands high force alongside serious radial load tolerance. If your task instead requires low-friction precision for a vertical high-load slide, the sister TCL series with its steel-ball linear bearing is the better route. To replace this unit, match the 50 mm bore, 80 mm stroke, 1/4" port, PT thread, and standard S magnet. Note that a TC cylinder will drift and drop its load if air pressure is lost, as the guide resists rotation but not gravity; install an external rod lock for fail-safe holding. Stroke ends rely on fixed rubber bumpers, so there is no cushion screw to tune.
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-TCM50X80S FAQ
This 50 mm bore cylinder generates 982 N of push and 825 N of pull at 0.5 MPa, and 1374 N of push at 0.7 MPa, with a theoretical maximum force of 200 kgf. It operates on filtered air between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
The B02- prefix simply marks this as a welding-industry dedicated variant of the TCM50X80S; it is mechanically identical to the base model with no special seals or dimensions. For end-of-stroke damping, it uses fixed rubber TPU bumpers at each end—there is no adjustable air cushion or cushion screw to set.
