About the Airtac MGC Stainless Steel Mini Cylinder MGC20X175
The AirTAC MGC20X175 is a double acting, JIS-standard round-body mini cylinder with a 20 mm bore and 175 mm stroke, fitted with a variable air cushion at both stroke ends. Unlike the bumper-type MG, the cushion needle is adjustable, so you can dial in smooth deceleration near end of travel and run higher piston speeds or heavier moving loads without hammering the covers. 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 maximum of 32 kgf at 1.0 MPa. The 8 mm hard-chrome plated rod carries an M8x1.25 male thread, and the air port is M5x0.8.
Construction follows the JIS mini-cylinder footprint: covers and stainless blocks are riveted and rolled onto a SUS304 stainless barrel, with a two-way piston seal that also stores lubricant, so there are no tie-rods and no extruded profile to service. Operating pressure is 0.15-1.0 MPa (22-145 psi) with a 1.5 MPa (215 psi) proof pressure, air filtered to 40 um, temperature range -20 to +70 C, and speeds of 30-800 mm/s. Mounting is via FA flange or LB foot, with I and Y rod knuckles available; add the optional S magnet code to enable CMSG, DMSG or EMSG switches. As a rule of thumb, keep vertical lifting loads to about 60 percent of push force, roughly 9 kg here.

Where the Airtac MGC Stainless Steel Mini Cylinder MGC20X175 Is Used
High-cycle small-part ejection
The variable air cushion lets this 20 mm bore cylinder run at the upper end of its 30-800 mm/s range and decelerate smoothly at stroke end, protecting the covers during fast push-off of small components.
Light diverting and stopping on conveyors
With 157 N push at 0.5 MPa and adjustable end-of-stroke deceleration, the MGC20X175 diverts or stops light cartons and trays without the jolt a non-cushioned mini cylinder would deliver.
Compact test and press fixtures
The SUS304 stainless barrel and hard-chrome rod resist corrosion in labs and light assembly stations, while the cushion gives controlled contact force for small pressing, marking or sample-handling fixtures.
Is the Airtac MGC Stainless Steel Mini Cylinder MGC20X175 the Right Cylinder?
At 20 mm bore this is the smallest MGC in the range, so there is no smaller cushioned option; if you need more force, step up to the 25 mm bore (245 N push at 0.5 MPa) or larger. If your application does not need adjustable deceleration, the plain bumper-type MG in 20 mm bore is the no-cushion alternative. Choose the MGC20X175 when a 175 mm stroke and up to 157 N of push at 0.5 MPa (219.8 N at 0.7 MPa) fit the job and you want the cushion to absorb end-of-stroke energy at higher speeds. Specify FA flange or LB foot mounting, I or Y rod knuckles where the load articulates, and the S magnet code if you need CMSG/DMSG/EMSG position sensing. For strokes beyond the 500 mm standard maximum, non-standard versions up to 800 mm are made to order. At long strokes, guide the load externally so side forces do not load the 8 mm rod.

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 MGC20X175 FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N; at 0.7 MPa those rise to 219.8 N push and 184.7 N pull. The theoretical maximum force at 1.0 MPa is 32 kgf. For safe vertical lifting, apply a rule of thumb of about 60 percent of push force, roughly 9 kg.
The cushion needle at each end is adjustable, letting you throttle the exhaust air so the piston decelerates smoothly near end of travel; it is an adjustable air cushion, not a fixed bumper pad. It only decelerates the stroke end and is not a lock or brake, so the MGC20X175 will not hold position on air loss. Use an external rod lock or pilot check valve for a held load.
