Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150S is a genuine guide-frame (guided) pneumatic cylinder — a Ø20mm double-acting MI mini cylinder built into a twin-rod guide unit running on brass bearings. The guide frame absorbs side load and torque so the 150mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150S
Built around a twin-rod aluminium guide frame on brass bearings, this double-acting AirTAC unit pairs an MIC round-body mini cylinder with a needle-set variable air cushion at both ends. The brass bearing yields high torsional stiffness and resists radial load, making it the right pick when a tool twists or pushes sideways. The frame absorbs side load and torque so the rod stays true, delivering smooth, quiet, square motion even at higher speeds.
At the 20 mm bore class, fluid filtered to 40 um operating at 0.5 MPa delivers 157 N of push and 131.9 N of pull, fed through a 1/8 inch port. For a safe working margin, plan for roughly 94 N of thrust, which pushes about 8 kg vertically with a 2:1 safety factor, load curve permitting. Remember that thrust does not set the load limit: the weight this frame can carry falls as the load sits further from the plate, so always confirm the allowable figure from the TMI/TMIC load-offset curves.

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 TMICM20X150S Is Used
High-Speed Transfer Pusher
Uses the 157 N push force to divert packages on a line, relying on the variable air cushion to decelerate the 150 mm stroke quietly at high cycle rates.
Multi-Axis Tool Head
Mounts a machining or drilling head that exerts torsional stress, where the brass bearings keep the twin-rod frame stiff and the tool plate square to the work.
Vertical Lift Gate
Lifts an 8 kg gate assembly vertically using a 2:1 safety margin on the 0.5 MPa thrust, provided the load-offset distance is approved on the load curve.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X150S the Right Cylinder?
Size this 20 mm bore both ways against your actual force needs. If 157 N of push at 0.5 MPa is too much, step down to the 16 mm bore (100.5 N push); if you need more muscle, the 25 mm bore offers 245.3 N. Choose this brass-bearing M variant over the linear-bearing TMICL when your application applies heavy side load or torsional stress to the tool plate. The variable air cushion is essential for high-speed or heavy-moving loads, using needle adjustment to decelerate the stroke smoothly without fixed bumper bounce.
Because this 150 mm stroke is standard for the 20 mm frame, it falls inside the 250 mm maximum. Always verify from the load-offset curve that your payload weight at its specific distance from the plate is within limits. This SKU includes the -S magnet, meaning it is ready to accept CMSG, DMSG, or EMSG sensors for position detection. Note that the guide frame resists side load but does not hold position on air loss; for a locked load, install an external rod lock or pilot check valve.

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 TMICM20X150S 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: the allowable payload depends on the load-offset distance and must be verified from the TMI/TMIC load curves.
Yes, the -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG switches. The needle-set variable air cushion only decelerates motion near stroke end for smooth stops; it is not a brake. The frame resists side load but on air loss the piston drifts, so use an external rod lock or pilot check valve to hold position.
