About the Airtac MG Stainless Steel Mini Air Cylinder MG20X100SLB
Compact and corrosion-ready, the MG20X100SLB is a double acting JIS round-body mini cylinder with a 20 mm bore and 100 mm stroke. Its SUS304 stainless barrel and hard-chrome plated 8 mm rod shrug off damp washdown corners that quickly ruin painted-steel minis, and the riveted covers keep the body short and light. At 0.5 MPa it delivers 157 N push and 131.9 N pull, rising to 219.8 N push at 0.7 MPa, with a theoretical ceiling of 32 kgf at 1.0 MPa.
In practice, plan on roughly 94 N of usable push at 0.5 MPa, which means this cylinder lifts about 8 kg vertically with a sensible margin. The fitted magnet (the S code) lets you mount CMSG, DMSG or EMSG switches for end-of-stroke signalling, and the fixed anti-impact bumper pads soften the direction change at each end. Note that the bumpers only decelerate the piston; if air is lost the rod drifts freely, so use an external rod lock or pilot check valve where a load must stay put.

Where the Airtac MG Stainless Steel Mini Air Cylinder MG20X100SLB Is Used
Small-part presence ejection
The built-in magnet and CMSG switch confirm rod position while the 157 N push at 0.5 MPa kicks rejected caps or components off a packaging line conveyor.
Bench-top test fixture clamping
About 94 N of practical clamping force at 0.5 MPa holds small housings or PCB assemblies in a lab jig, and the stainless barrel wipes clean after coolant splashes.
Light lift-and-lower station
Lifts roughly 8 kg vertically with margin, lowering filled vials or small trays between levels on an assembly bench at speeds from 30 to 800 mm/s.
Is the Airtac MG Stainless Steel Mini Air Cylinder MG20X100SLB the Right Cylinder?
At 157 N push (0.5 MPa) this 20 mm bore suits light clamping, ejecting and small-part transfer up to about 8 kg vertical lift. If you need more muscle in the same JIS footprint, step up to the 25 mm bore MG for 245 N push, or drop to a smaller non-MG actuator since 20 mm is the smallest MG bore. The LB foot mount bolts down on a base plate; switch to FA flange, CB clevis or SDB pivot if the kinematics demand it. The 100 mm stroke is well within the 500 mm standard range, and the 8 mm rod tolerates only modest side load, so guide the load externally on long or offset strokes.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion/impact settings and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MG Stainless Steel Mini Air Cylinder MG20X100SLB FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N; at 0.7 MPa those figures rise to 219.8 N push and 184.7 N pull. The theoretical maximum is 32 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, and rod speed runs 30-800 mm/s.
The S in MG20X100SLB means a magnet is built into the piston, so CMSG, DMSG or EMSG reed/solid-state switches can be clipped onto the 1/8"-ported body to signal extend and retract positions. A standard MG without the S code has no magnet and cannot drive these sensors.
