Airtac TMIC Guided Cylinder with Guide Unit TMICL20X250
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X250 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 250mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X250
Built around a 20 mm bore double-acting MIC unit, the TMICL20X250 guide-frame cylinder integrates twin-rod linear bearings with a needle-set variable air cushion at both ends. This combination soaks up high-speed shock for quiet, square stops while the frame carries side load and torque. At 250 mm, this model hits the maximum standard stroke for this bore, delivering 157 N push and 131.9 N pull at 0.5 MPa through a 1/8" port.
Because the linear bearings yield low friction and high precision, this unit excels in vertical push-up applications where smooth travel matters. A practical buyer insight: safe working thrust is roughly 94 N, pushing about 8 kg vertically with a 2:1 margin, load permitting. The actual payload limit depends on the load-offset distance, so always confirm allowable values from the maximum-load curve rather than relying on thrust alone.

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 TMICL20X250 Is Used
Vertical Press Push-Up
Leverages the 157 N push force and low-friction linear bearings to press light components downward smoothly without rod deflection.
Long-Stroke Diverting
Uses the full 250 mm travel to shift packages between belts, relying on the twin-rod frame to resist torsional stress during rapid lateral transfers.
High-Speed Insertion
Benefits from the needle-set variable air cushion to decelerate the 8 kg payload safely at stroke end, ensuring quiet and square component seating.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X250 the Right Cylinder?
When sizing this 20 mm frame, compare it both ways: step down to a TMICL16X250 for lighter duty (100.5 N push @0.5 MPa) or up to a TMICL25X250 for heavier loads (245.3 N push @0.5 MPa). Choose these linear bearings over the brass-bearing TMICM when low friction and precise travel outweigh torsional stiffness. The variable air cushion is essential here for high-speed moves or heavy payloads, preventing hard end-impact.
Remember that the load it can carry falls as the weight sits further from the plate, so size strictly from the load-offset curve. This specific SKU lacks a magnet and cannot take a sensor; order the -S variant if you require CMSG, DMSG, or EMSG switches. For position holding on air loss, add an external rod lock or pilot check valve, as the cushion only decelerates.
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 TMICL20X250 FAQ
This 20 mm bore double-acting cylinder delivers 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push at 0.7 MPa, and a theoretical max of 32 kgf at 1.0 MPa. However, thrust is not the guided-load limit; the actual payload depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. It runs on linear bearings for low-friction, high-precision travel ideal for vertical push-ups, and features a variable air cushion at both ends that decelerates the load near stroke end for smooth, quiet motion. It does not hold position on air loss.
