Airtac TMIC Guided Cylinder with Guide Unit TMICL20X125
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICL20X125 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 125mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X125
Built around an MIC mini cylinder inside a twin-rod aluminium guide frame, the TMICL20X125 delivers 125 mm of guided travel on linear bearings. The needle-set variable air cushion at both ends absorbs high-speed end-of-stroke shock, ensuring smooth, quiet motion while the frame handles side load and torque. This 20 mm bore unit pushes 157 N and pulls 131.9 N at 0.5 MPa, using a 1/8" port.
Because the frame carries the structural load, you must size the allowable payload from the TMI load-offset curve rather than the thrust figures. Linear bearings provide low friction and high precision, making this variant the top choice for vertical push-up applications. For a safe working margin, expect about 94 N of thrust (roughly 8 kg of vertical push, load curve permitting). Note this specific SKU lacks a magnet and cannot host 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 TMICL20X125 Is Used
Vertical Push-Up Assembly
Leverages the low-friction linear bearings to raise an 8 kg fixture smoothly, while the air cushion decelerates the 125 mm stroke without jarring the part.
High-Speed Product Diversion
Uses the 157 N push force to deflect items on a belt; the twin-rod frame absorbs the side impact so the rod stays true over thousands of cycles.
Precision Glue Dispensing
The guided frame maintains exact tip alignment across the 125 mm travel, while the needle-set cushion ensures a soft stop to prevent glue splatter.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICL20X125 the Right Cylinder?
When sizing this 20 mm bore unit, consider the 16 mm variant (100.5 N push @0.5 MPa) for lighter duties, or step up to the 25 mm bore (245.3 N push @0.5 MPa) if your payload requires more force. Choose these linear bearings over the brass-bearing TMICM when friction and precise travel matter more than torsional stiffness. The variable air cushion is essential for high-speed moves, decelerating the load smoothly before the end of stroke.
Always verify the maximum payload against the load-offset curve, as allowable weight drops significantly the further the load sits from the plate. Since this SKU is not -S coded, it has no magnet and cannot support position sensing; order the -S variant if you require CMSG, DMSG or EMSG switches. For loads that must hold position on air loss, add an external rod lock or pilot check valve.
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 TMICL20X125 FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N; at 0.7 MPa it pushes 219.8 N and pulls 184.7 N, with a theoretical max of 32 kgf at 1.0 MPa. Thrust is not the guided-load limit—you must confirm the actual allowable payload from the TMI load-offset curve.
This specific SKU has no magnet and cannot accept CMSG, DMSG or EMSG switches; you need the -S variant for sensing. The variable air cushion at both ends uses a needle valve to decelerate the load near stroke end for smooth motion, but it is not a brake or position lock.
