Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM50X125S
The AirTAC Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM50X125S is a genuine JIS-standard guided cylinder with a Ø50mm 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 ±0.05° of rotation without any external linear guide.

About the Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM50X125S
The AirTAC B07-TCM50X125S is a JIS guided twin-rod double-acting cylinder built for automotive assembly lines, where the B07- prefix designates this as the vehicle-industry dedicated variant of the standard TCM50X125S. Mechanically identical to its base model, it integrates a drive piston between two guide rods supported by a brass sliding bearing. This construction completely eliminates the need for an external linear rail, handling heavy side loads and knocks with roughly double the horizontal impact resistance of a plain cylinder.
Delivering 982 N of push at 0.5 MPa, this 50 mm bore unit uses a Ø20 mm piston rod and 1/4" ports. The twin-rod geometry holds a non-rotating tolerance of ±0.05°, keeping a gripper or fixture perfectly square under off-centre loads. Stroke termination relies on fixed TPU bumpers at each end, as there is no adjustable air cushion. Furthermore, the cylinder will not hold a load if air pressure drops, requiring an external rod lock for fail-safe vertical holding.

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 B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM50X125S Is Used
Automotive Pallet Stop
Halts heavy chassis skids on an assembly line; the brass sliding bearing shrugs off weld spatter and grit while the 982 N push force securely gates the moving load.
Off-Centre Gripper Slide
Transfers engine blocks between stations; the ±0.05° non-rotating accuracy keeps the wide gripper square under offset mass without needing a separate guide rail.
Door Hinge Press
Drives a pinning fixture for body panels; the impact-tolerant brass sleeve survives repeated hard end-stops where a steel-ball bearing would jam from debris.
Is the Airtac B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM50X125S the Right Cylinder?
When sizing this unit, compare its 982 N push (at 0.5 MPa) against adjacent bores: stepping down to a Ø40 yields 628 N, while moving up to a Ø63 provides 1559 N. Choose the TCL series instead if your task demands low-friction steel-ball precision for vertical high-load work. To replace this SKU, match the 50 mm bore, 125 mm stroke, 1/4" port, PT thread form, and standard S magnet. The 125 mm stroke falls well within the 250 mm standard limit, so no made-to-order wait 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 B07-TCM Automotive-Specific Triaxial Cylinder B07-TCM50X125S FAQ
At 0.5 MPa it provides 982 N of push and 825 N of pull. At 0.7 MPa the push increases to 1374 N, with a theoretical maximum force of 200 kgf. Operating pressure spans 0.15-1.0 MPa, and speed ranges from 30-500 mm/s.
The B07- prefix marks this as an automotive-industry dedicated variant; mechanically it is identical to the TCM50X125S. It includes a standard built-in magnet (S) compatible with AirTAC CS1 reed or DS1 electronic switches, which fit into any of the four sensor slots on the body.
