Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X90S
The AirTAC Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X90S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 90mm 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-TCM32X90S
The B02-TCM32X90S is AirTAC's welding-industry dedicated variant of the TCM32X90S, engineered for robot and spot welding cells where spatter and grit are prevalent. The "B02-" prefix designates this specific automation application without altering the base mechanics: it remains a JIS-standard, double-acting twin-rod guided cylinder. A central drive piston runs between two guide rods supported by a brass sliding bearing, integrating the drive and guide into one compact body to eliminate the need for an external linear rail.
Delivering 402 N of push at 0.5 MPa, this 32 mm bore unit carries heavy off-centre loads with a non-rotating accuracy of ±0.06°. The brass sliding bearing is the core advantage here, shrugging off metallic dust and hard knocks that would jam a steel-ball linear guide. It features a Ø16 mm piston rod, 1/8" PT ports, and fixed TPU bumpers at both ends to soften stroke stops without requiring adjustment. Two independent upper and side port groups allow pneumatic plumbing from whichever machine face has clearance.

| Acting type | Double acting |
| Bearing | Brass sliding bearing |
| Port size | 1/8" |
| 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 | ±0.06° (retracted) |
| Cushion | Rubber bumper |
| Max std stroke | Up to 250 mm |
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 (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 302 N |
| 0.7 MPa | 563 N | — |
| Max | 82 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-TCM32X90S Is Used
Robot Welding Clamp
Holding an off-centre fixture jaw square against a weldment. The brass sliding bearing tolerates weld spatter and dust where a ball guide would seize, while 402 N of thrust secures the part.
Weld Cell Pallet Stop
Gating heavy pallets entering a robot weld station. The twin guide rods absorb the radial impact of arriving loads, and the ±0.06° anti-rotation tolerance keeps the stop blade perfectly aligned.
Spot Weld Gun Positioning
Feeding a spot weld tip into place. The integrated guide removes the need to align a separate rail, and the brass bearing handles the side-load of the gun without premature wear.
Is the Airtac B02-TCM Welding Dedicated Triple-Axis Cylinder B02-TCM32X90S the Right Cylinder?
When sizing this model, stepping down to a Ø25 bore yields roughly 245 N of thrust at 0.5 MPa, whereas stepping up to a Ø40 bore provides 628 N. Choose the TCL series instead if your welding fixture demands high-precision vertical movement, as its steel-ball linear bearing offers lower friction than this brass slide. To replace this unit, match the 32 mm bore, 90 mm stroke, 1/8" port, PT thread, and the standard S magnet. Note that a TCM does not hold its vertical position if air pressure drops; the guide prevents rotation but not gravity drift, so fit an external pilot check valve if a fail-safe drop prevention is required.
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-TCM32X90S FAQ
At 0.5 MPa it generates 402 N of push and 302 N of pull; at 0.7 MPa the push increases to 563 N, with a theoretical maximum force of 82 kgf. It operates on filtered air at 0.15-1.0 MPa, runs at 30-500 mm/s, and the 1/8" ports are PT threaded.
The B02- prefix marks this as AirTAC's welding-industry dedicated line; mechanically it is identical to the standard TCM32X90S. It uses fixed rubber TPU bumpers at each end to absorb the stop, meaning there is no adjustable air cushion screw to set. It also ships with a standard built-in magnet for CS1 reed or DS1 electronic sensors.
