Airtac TCM Triple Axis Cylinder TCM50X90-S
The AirTAC Airtac TCM Triple Axis Cylinder TCM50X90-S is a genuine JIS-standard guided cylinder with a Ø50mm 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 ±0.05° of rotation without any external linear guide.

About the Airtac TCM Triple Axis Cylinder TCM50X90-S
The AirTAC TCM50X90-S is a JIS-standard twin-rod guided cylinder with a brass sliding bearing. A central Ø20 piston rod drives the load while two flanking guide rods absorb radial force and torque, eliminating the need for an external linear rail. Delivering 982 N of push at 0.5 MPa, this double-acting unit handles heavy side loads with a ±0.05° non-rotating tolerance, keeping wide grippers or plates perfectly square.
Built for harsh environments, the brass sliding bearing shrugs off weld spatter, coolant, and grit where a steel-ball guide would jam, offering roughly twice the horizontal impact resistance of a plain cylinder. The 1/4" PT ports can be plumbed from the upper face or side, and a moulded rubber bumper absorbs the stop at both ends, with no air-cushion screw to set. A standard built-in magnet pairs with CS1 reed or DS1 electronic switches in the four body 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 (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 TCM Triple Axis Cylinder TCM50X90-S Is Used
Pallet Transfer Line Stop
Halting heavy pallets moving down a dusty conveyor, the brass sliding bearing tolerates abrasive grit while delivering 982 N of stopping force at 0.5 MPa without needing a separate shock absorber.
Off-Centre Gripper Slide
Lifting an asymmetric part, the twin guide rods maintain a ±0.05° non-rotating tolerance, keeping the wide gripper plate square and absorbing the induced torsional load.
Weld-Cell Clamp Positioner
Positioning a heavy weld clamp in a dirty cell, the brass sleeve resists spatter and contamination where a ball bearing would jam, while providing 1374 N of clamping thrust at 0.7 MPa.
Is the Airtac TCM Triple Axis Cylinder TCM50X90-S the Right Cylinder?
If 982 N of thrust is more than your space allows, stepping down to the Ø40 bore provides about 628 N of push at 0.5 MPa. For heavier gating or pressing demands, moving up to the Ø63 bore yields 1559 N. Both neighbours use the same 30-500 mm/s speed range and 0.15-1.0 MPa operating pressure.
Choose the sister TCL series with its steel-ball linear bearing only if your task demands low-friction precision or vertical high-load handling. Note that this TCM does not hold its load if air pressure is lost; the rod drifts, so fit an external rod lock or pilot-operated check valve for fail-safe positioning. This 90 mm stroke is a standard length, and the built-in S magnet is standard across the range.
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 TCM Triple Axis Cylinder TCM50X90-S FAQ
At 0.5 MPa, the Ø50 bore delivers 982 N of push and 825 N of pull. At the maximum 0.7 MPa operating pressure, the push force reaches 1374 N. The theoretical maximum force is 200 kgf.
The TCM uses an impact-tolerant brass sliding bearing for dirty, heavy-radial duty, whereas the TCL uses a low-friction steel-ball linear bearing for high-precision vertical work. This unit ships with a standard built-in magnet compatible with AirTAC CS1 reed and DS1 electronic switches in any of the four body slots.
