The AirTAC Airtac TCM Triple Axis Cylinder TCM20X50S is a genuine JIS-standard guided cylinder with a Ø20mm bore and 50mm 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 ±0.08° of rotation without any external linear guide.
The AirTAC TCM20X50S is a JIS-standard twin-rod guided cylinder featuring a robust brass sliding bearing. It integrates the drive piston and two guide rods into a single body, eliminating the need for an external linear rail. Generating 157 N of push and 118 N of pull at 0.5 MPa, this double-acting unit handles off-centre loads with a non-rotating accuracy of ±0.08°.
Designed for harsh environments, the brass sliding bearing shrugs off dust, weld spatter, and hard knocks, providing roughly twice the horizontal impact resistance of a plain cylinder. The Ø10 mm piston rod operates on 1/8" ports, while fixed TPU bumpers absorb end-of-stroke shocks without requiring any cushion adjustment. A standard built-in magnet enables position feedback via CS1 reed or DS1 electronic switches in 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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 118 N |
| 0.7 MPa | 220 N | — |
| Max | 32 kgf | |
Force is set by the bore and piston rod (Ø10 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.

Sister type: TCL20X50 (steel-ball linear bearing, lower friction & higher precision). Thread codes: blank = PT · G · T = NPT.
Tolerates weld spatter and grit where a ball guide would jam, using its 157 N push to hold a 50 mm clamping stroke square against off-centre parts.
The brass sliding bearing survives abrasive dust while stopping moving pallets, maintaining ±0.08° non-rotating accuracy to prevent gate binding.
Absorbs lateral knocks during part handling, using the twin guide rods to keep the gripper plate square without needing a separate linear rail.
This 20 mm bore provides 157 N of thrust at 0.5 MPa. If you need less force, stepping down to the Ø16 bore yields 101 N of push; moving up to the Ø25 bore provides 245 N. Choose the sister TCL series with its steel-ball linear bearing instead if your application demands low-friction precision or high vertical loading. To replace this unit, match the 20 mm bore, 50 mm stroke, 1/8" PT ports, and standard S magnet. Note that air pressure drives both directions; if air is lost, the rod drifts and drops, so add an external rod lock for fail-safe holding.
Quick checklist
At 0.5 MPa it generates 157 N of push and 118 N of pull. At 0.7 MPa the push increases to 220 N. The theoretical maximum force is 32 kgf.
No, the TC series uses fixed rubber TPU bumpers at each end to soften the stop. There is no adjustable air cushion or cushion screw to set.
