The Airtac TCL12X20S is a double-acting tri-rod guided cylinder from the AirTAC TCL/TCM series with a 12 mm bore and 20 mm stroke. The piston rod and two guide rods are tied to one front plate, and the guides run in linear ball bearings (L), so the plate resists turning and side load without an external guide.
Reading the code: TC = tri-rod cylinder (double acting), L = linear bearing, 12×20 = bore x stroke in mm, S = with magnet (every TC cylinder has one, for position sensing); no thread suffix means the standard port thread.

Typical applications
- Press-fit, clamping and lifting stations on assembly machines
- Pick-and-place and transfer units that need a non-rotating plate
- Stoppers and pushers on conveyor lines
- Gate, diverter and reject mechanisms on packaging lines
- Like-for-like replacement of an Airtac TCL12X20S
Compatibility and replacement
The TCL and TCM versions of the same bore and stroke share the ordering code layout; TCL guides run in linear ball bearings, TCM guides in brass slide bearings, and AirTAC lists tighter non-rotating accuracy and different safe-torque values for each. Port threads other than the standard are ordered with a suffix (for example T for NPT). When replacing an existing unit, match bore, stroke, bearing letter and the thread suffix printed on the old cylinder label.
Frequently asked questions
Should I choose TCL12X20S or the TCM version?
TCL (linear bearing) is what you have here. Per AirTAC, the non-rotating accuracy of this bore is ±0.08° for TCL and ±0.10° for TCM. Check the safe-torque table for your stroke as well; when replacing a cylinder, keep the bearing letter on the old label so the machine behaves the same.
How fast can it run?
AirTAC gives a speed range of 30-500 mm/s for this bore, with bumper cushioning. Use speed-control fittings to set the speed and keep impact at the stroke ends low.
What air supply does it need?
Clean compressed air filtered to 40 µm, between 0.15-1.0 MPa (22-145 psi). The M5x0.8 ports take standard push-in fittings of that thread.
