Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25S is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm double-acting MI mini cylinder built into a twin-rod guide unit running on linear bearings. The guide frame absorbs side load and torque so the 25mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25S
Built around an MIC mini cylinder inside a twin-rod aluminium guide frame, the TMICL20X25S delivers precise double-acting motion on linear bearings. The needle-set variable air cushion at both ends absorbs high-speed shock for smooth, square stops, while the frame handles side load and torque so the rod stays true. It is a ready-to-mount linear slide, not a bare cylinder.
At 20 mm bore with an 8 mm rod and 1/8" port, this unit pushes 157 N and pulls 131.9 N at 0.5 MPa. That translates to a safe working thrust of roughly 94 N, or about 8 kg of vertical push with a 2:1 margin, load curve permitting. The frame resists side load but does not hold position on air loss, so add an external rod lock for suspended loads. The -S suffix means a piston magnet is installed for CMSG, DMSG or EMSG sensors.

Specifications follow the official AirTAC TMI/TMIC datasheet. Guide frame & fixed plate: aluminum alloy; matching cylinder: MI/MIC round-body mini cylinder. Allowable load depends on the load-offset distance — consult the TMI/TMIC maximum-load curves before final selection. Thread options: PT (blank) / G.
Theoretical Output Force (Ø20mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | 185 N |
| Max (@1.0 MPa) | 32 kgf | |
Thrust equals the underlying MI cylinder. The usable load a guide frame can carry is limited by the load-offset curve, not by thrust alone — always check both. Actual force is lower than theoretical due to friction and back-pressure.

Where the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25S Is Used
Vertical Push-Up Assembly
Ideal for pushing an 8 kg component upward into a fixture, utilizing the low-friction linear bearings for smooth vertical travel and the cushion to soften the end of stroke.
High-Speed Part Insertion
Handles rapid horizontal insertion of small electronic connectors where the twin-rod frame maintains alignment and the needle-set air cushion prevents end-of-stroke shock.
Pallet Stopper Gate
Acts as a precise stop block for lightweight pallets on a conveyor, using the 157 N thrust to halt movement and the magnet for position confirmation.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25S the Right Cylinder?
Size this 20 mm bore model by checking both thrust and load capacity. If your application needs less force, the 16 mm bore variant offers 100.5 N push at 0.5 MPa; for heavier moves, the 25 mm bore provides 245.3 N. Choose these linear bearings over the brass-bearing TMICM when low friction and high travel precision matter more than torsional stiffness. The variable air cushion is essential for high-speed or heavy loads, but remember the allowable load falls as the offset distance grows, so always verify the exact figure from the load curve. Ensure your mounting setup matches the 25 mm stroke and order the -S version if you need position sensing.
Quick checklist
- ✓ Required thrust at your working pressure
- ✓ Load and offset within the load curve
- ✓ Bearing: brass (torque) vs linear (precision)
- ✓ Stroke and mounting space
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep the load within the load-offset curve.
- check Mount on a flat, rigid surface using the fixed plate.
- check Do not exceed the rated speed (30-500 mm/s).
- check Installation by qualified personnel per AirTAC docs.
Airtac TMIC Guided Cylinder with Guide Unit TMICL20X25S FAQ
This 20 mm bore cylinder provides 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa. However, thrust is not the guided-load limit; the actual load it can carry depends on the load-offset distance and must be read from the TMI/TMIC maximum-load curves.
It features a variable air cushion at both ends that decelerates the piston near stroke ends for smooth, quiet motion, but it is not a lock or brake. The linear bearings provide high precision for vertical push-up moves, but on air loss the piston will drift. For holding a suspended load, use an external rod lock or pilot check valve. The -S suffix enables CMSG, DMSG and EMSG sensors.
