Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM32X125S
The AirTAC Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM32X125S is a genuine JIS-standard guided cylinder with a Ø32mm bore and 125mm 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 B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM32X125S
The B07-TCM32X125S is an AirTAC JIS guided twin-rod cylinder engineered for automotive assembly lines, where the "B07-" prefix designates this as the vehicle-industry dedicated variant of the standard TCM32X125S. Mechanically identical to its base model, it integrates a drive piston between two guide rods within a single body. This construction entirely removes the need for an external linear slide, saving space and eliminating alignment work. The brass sliding bearing is specifically chosen for dirty, knocking duty; it shrugs off weld spatter, grit, and coolant where a steel-ball guide would jam, providing roughly double the horizontal impact resistance of a plain cylinder.
Operating double-acting on 1/8" ports with a Ø16 mm piston rod, this unit delivers 402 N of push at 0.5 MPa. The twin guide rods hold a strict ±0.06° non-rotating tolerance, keeping a gripper or clamping plate perfectly square under off-centre loads. Stroke ends are damped by fixed elastomer pads rather than an adjustable cushion, absorbing shock without requiring tuning. Two independent port groups (upper face and side) let you feed air from whichever direction is clear, while the standard built-in magnet pairs with CS1 reed or DS1 electronic switches in any of the four sensor slots.

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 B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM32X125S Is Used
Automotive Body Panel Stop
Halts moving chassis skids on the assembly line. The brass sliding bearing tolerates weld spatter and factory grit, while 402 N of push firmly gates the load without rotating under eccentric impact.
Off-Centre Gripper Slide
Actuates a heavy parts gripper during robotic transfer. The ±0.06° non-rotating accuracy keeps the jaws square against offset weight, and the twin-rod guide absorbs the radial load without an external rail.
Stamping Press Feed
Pushes metal blanks into the press bed. The robust brass sleeve survives heavy side-loading and repetitive mechanical knocks, shrugging off coolant and debris where a linear ball bearing would fail.
Is the Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM32X125S the Right Cylinder?
This 32 mm bore provides 402 N push and 302 N pull at 0.5 MPa. If you need less force, step down to the Ø25 bore which yields roughly 245 N of thrust; if your fixture requires more power, the Ø40 bore delivers about 628 N. When your application demands high-precision vertical movement or ultra-low friction instead of impact tolerance, select the sister TCL series with its steel-ball linear bearing. To replace this unit, match the 32 mm bore, 125 mm stroke, 1/8" port size, and PT thread form; the magnet (S) is standard. Note that a guided cylinder drifts if air pressure is lost or the valve is centred, so fit an external rod lock or pilot check valve if the load must stay put.
Regarding the thread form, the ports are PT (tapered) by default unless the code specifies G (BSPP) or T (NPT). This 125 mm stroke falls well within the 250 mm maximum standard stroke for a 32 mm bore, ensuring standard dimensions and immediate availability.
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 B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM32X125S 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 between 0.15-1.0 MPa, runs at 30-500 mm/s, and has a proof pressure of 1.5 MPa.
The B07- prefix marks this as AirTAC's automotive-industry dedicated variant of the TCM32X125S; mechanically, the bore, stroke, and specs are identical to the base model. Each end of the stroke lands on a fixed TPU rubber bumper—there is no adjustable air cushion or cushion screw to set.
