Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X60S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X60S is a genuine JIS-standard guided cylinder with a Ø40mm bore and 60mm 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 ±0.06° of rotation without any external linear guide.

About the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X60S
The B02-TCM40X60S is AirTAC's welding-industry dedicated variant of the TCM40X60S, mechanically identical to the base JIS guided twin-rod cylinder. A central drive piston runs between two guide rods supported by a brass sliding bearing, integrating the actuator and linear guide into one body to eliminate external rails. The B02- prefix simply designates its optimization for welding-line automation, without altering the core physical specs. Delivering 628 N of push at 0.5 MPa, this double-acting unit handles solid mid-weight clamping tasks. Its brass sliding bearing shrugs off grit and hard knocks, offering about twice the horizontal impact resistance of a plain cylinder where a steel-ball guide would jam from contamination. Anti-rotation precision is held to ±0.06°, keeping a fixture or clamp plate perfectly square under off-centre loads. Stroke termination relies on fixed TPU rubber bumpers at each end, deliberately omitting adjustable air cushions to keep the mechanism robust and simple.
Plumbing is simplified by two independent port groups on the upper face and side, allowing 1/8" air lines to connect from whichever direction is clear of the cell. The Ø16 mm piston rod moves at 30-500 mm/s, and the standard built-in magnet feeds position signals to CS1 reed or DS1 electronic switches mounted in any of the four sensor slots. Thread form is PT as standard. Note that while the twin-rod guide resists torsion, it will not hold a load vertically if air pressure drops; fit an external rod lock for fail-safe clamping.

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 (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max | 128 kgf | |
Force is set by the bore and piston rod (Ø16 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-TCM40X60S Is Used
Spot Welding Cell Clamp
Holds heavy steel panels in a robot spot-welding cell. The brass sliding bearing tolerates weld spatter and knocking where a ball guide would fail, while 628 N of push secures the part.
Off-Centre Gripper Slide
Actuates an offset gripper on a transfer line. The ±0.06° non-rotating tolerance keeps the jaws square under asymmetric load, preventing workpiece distortion during handling.
Weldment Pallet Stop
Halts pallets carrying raw weldments at a staging station. Twin guide rods absorb the radial impact of the arriving load, leveraging roughly double the impact resistance of a plain cylinder.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM40X60S the Right Cylinder?
Selecting this 40 mm bore provides 628 N of thrust at 0.5 MPa (880 N at 0.7 MPa). If your welding fixture needs less force, stepping down to the Ø32 bore yields 402 N of push, while moving up to the Ø50 bore provides 982 N for heavier stamping or holding duties. When precision linear movement with low friction is required instead of impact tolerance, the sister TCL series with its steel-ball linear bearing is the better choice for vertical or high-load sliding. To replace this unit, specify the full B02-TCM40X60S code, confirm the 1/8" PT ports, the 60 mm stroke, and the standard S magnet. A 60 mm stroke is well within the 250 mm maximum for this bore, so it ships as a standard catalog item. Remember that the guide prevents rotation but not gravity drop; add a pilot check valve if the clamp must stay engaged during an air loss event.
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-TCM40X60S FAQ
At 0.5 MPa it generates 628 N of push and 528 N of pull. At 0.7 MPa the push force is 880 N, with a theoretical maximum force of 128 kgf. Operating pressure spans 0.15-1.0 MPa, and the cylinder runs at speeds of 30-500 mm/s.
The B02- prefix denotes AirTAC's welding-industry dedicated line; mechanically, it is identical to the standard TCM40X60S guided cylinder. It uses fixed rubber TPU bumpers at both stroke ends to absorb impacts, meaning there is no adjustable air cushion or cushion screw to set or maintain.
