Airtac TMIC Guided Cylinder with Guide Unit TMICM20X100S
The AirTAC Airtac TMIC Guided Cylinder with Guide Unit TMICM20X100S 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 100mm stroke stays true, giving you a ready-to-mount linear slide without a separate guide.

About the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X100S
Built around a twin-rod aluminium guide frame on brass bearings, the TMICM20X100S is a double-acting guided cylinder that keeps the rod true under twisting and side loads. A needle-set variable air cushion at both ends soaks up high-speed shock for smooth, square motion. The 20 mm bore delivers 157 N of push force at 0.5 MPa, making it a solid mid-range choice for demanding pick-and-place tasks.
The brass bearing design gives high torsional stiffness, so it shrugs off radial loads that would deflect a bare cylinder. With a 100 mm stroke and a 1/8" port, it moves at 30-500 mm/s. Remember that the allowable load falls as the weight sits further from the plate; always size from the load-offset curve rather than relying on thrust alone. The built-in magnet (-S) supports CMSG, DMSG, and 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 TMICM20X100S Is Used
High-Speed Part Transfer
Uses the variable air cushion to decelerate a 5 kg tooling plate smoothly across the 100 mm stroke, eliminating end-impact shock on rapid cycles.
Lateral Carton Pusher
Leverages the brass bearings' torsional stiffness to push offset cartons sideways without rod deflection, handling loads that would twist a standard cylinder.
Vertical Component Lift
Pushes up to 8 kg of components with a 2:1 safety margin at 0.5 MPa, using the twin-rod frame to keep the lift square under asymmetrical weight.
Is the Airtac TMIC Guided Cylinder with Guide Unit TMICM20X100S the Right Cylinder?
Size this model against its siblings: step down to the 16 mm bore (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 you need more force. Choose this brass-bearing TMICM variant when the load twists or pushes sideways; switch to the TMICL if you need lower-friction linear bearings. The variable air cushion matters most when cycling at high speeds or moving heavy masses, preventing end-of-stroke banging.
For vertical lifts, the 157 N thrust at 0.5 MPa gives a safe working thrust of about 94 N, pushing roughly 8 kg vertically with a 2:1 safety margin—provided the load-offset curve allows it. The guide frame resists side load but does not hold position on air loss; the piston will drift. For a locked load, add an external rod lock or pilot check valve. The -S magnet on this unit is required for CMSG/DMSG/EMSG switches.

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 TMICM20X100S 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 load depends on the load-offset distance and must be verified from the TMI/TMIC maximum-load curves.
It features a needle-set variable air cushion at both ends that decelerates the piston near stroke end for quiet, shock-free motion; it is not a brake. The brass bearings handle side load, but on air loss the piston drifts. The -S magnet enables CMSG/DMSG/EMSG sensors for position detection.
