About the Airtac MGC Stainless Steel Mini Cylinder MGC50X150S
The AirTAC MGC50X150S is a JIS-standard round-body mini cylinder, double acting, with a variable air cushion at both stroke ends. Its 50 mm bore delivers 981.3 N push and 824.3 N pull at 0.5 MPa (72.5 psi), rising to 1373.8 N push at 0.7 MPa (101.5 psi), with a theoretical maximum of 200.1 kgf at 1.0 MPa (145 psi). The 150 mm stroke is a standard length within the 500 mm maximum for this bore, and the fitted magnet allows CMSG, DMSG or EMSG switch mounting for end-position sensing.
What sets this model apart from the bumper-type MG is the adjustable cushion: turn the needle valve at each end to dial in deceleration, so the piston settles smoothly instead of hammering the covers. That makes the MGC50X150S a better choice at higher piston speeds (up to 800 mm/s) or with heavier moving loads. The barrel is SUS304 stainless steel rolled onto the covers, the 20 mm rod is hard-chrome plated to 20 um, and the two-way piston seal also stores lubricant. Ports are 1/4", the male rod thread is M18x1.5, and mounting is via FA flange or LB foot with I and Y rod knuckles available. Note that the cushion only decelerates the stroke end; it is not a lock, so use an external rod lock or pilot check valve if the load must be held on air loss.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC50X150S Is Used
Conveyor stop and divert
The variable air cushion lets the 50 mm bore stop moving product at high line speeds without slamming the covers, while the 981.3 N push at 0.5 MPa handles heavier cartons.
Case clamp and press-fit
Around 100 kgf of push force at 0.5 MPa (72.5 psi) with smooth end-of-stroke deceleration suits clamping or light pressing in packaging machinery, with EMSG sensing on the fitted magnet.
Palletizer pusher arm
Double acting push and pull (981.3 N / 824.3 N at 0.5 MPa) plus adjustable cushioning make this cylinder a good fit for pusher arms that cycle fast and stop against a load.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC50X150S the Right Cylinder?
At 50 mm bore this is the second-largest cushioned MGC: 981.3 N push at 0.5 MPa (72.5 psi), about 100 kgf, of which roughly 60 kg is a safe working figure for horizontal or vertical duty (about 30 kg vertical lift with a 0.5 safety factor). If you need more force, step up to the 63 mm bore (1557.9 N push at 0.5 MPa); if you need less, the 40 mm bore gives 628.3 N. For bores 20 to 40 where no cushion is needed, the plain bumper MG is the lower-cost alternative. Choose the -S suffix (as here) only if you will mount CMSG, DMSG or EMSG switches. Pick FA flange or LB foot mounting, and PT, G or NPT ports. At 150 mm stroke the 20 mm rod is fine for axial loads, but for long strokes near the 500 mm standard maximum (or made-to-order strokes to 800 mm) guide side loads externally to protect the rod and bushing.

- ✓ Magnet (-S) for sensors?
- ✓ Mounting (LB / FA) & knuckle
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 and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MGC Stainless Steel Mini Cylinder MGC50X150S FAQ
At 0.5 MPa (72.5 psi) it pushes 981.3 N and pulls 824.3 N; at 0.7 MPa (101.5 psi) it pushes 1373.8 N and pulls 1154 N; theoretical maximum is 200.1 kgf at 1.0 MPa (145 psi). A practical rule of thumb is to size at about 0.6 of the 0.5 MPa push force, so roughly 60 kg safe working load, or about 30 kg for vertical lifting.
The needle at each stroke end throttles exhaust air to decelerate the piston smoothly, and you adjust it to match speed and load; it is an adjustable air cushion, not a fixed bumper pad. It only cushions the end of travel, so it is not a position lock. If the load must be held on air loss, add an external rod lock or pilot check valve. The SUS304 stainless barrel and hard-chrome 20 mm rod suit washdown-prone areas, and the fitted magnet accepts CMSG, DMSG or EMSG switches.
