About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X50
The AirTAC MGCD40X50 is a double acting, double rod JIS round-body mini cylinder with a 40 mm bore and 50 mm stroke. Because a 16 mm hard-chrome rod exits both covers with the same M14x1.5 male thread at each end, the piston works on the rod-side area in both directions, so the output force is equal either way: about 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. A variable air cushion at both ends lets you dial in smooth deceleration at each end of travel, so this 40 mm cylinder can run at higher speeds or carry heavier loads without hard metal-to-metal stops. The rear rod end also gives you a second working surface for a stop, flag or second load, and the through-rod resists rotation.
Construction follows the JIS mini-cylinder footprint: a riveted round body in SUS304 stainless steel with hard-chrome plated rods for long seal and bearing life. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), handles proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C and covers speeds of 30-800 mm/s. Ports are 1/8" on both ends. For a realistic working load, size around 60% of the push force, roughly 316 N, which is about 32 kgf; halved for a vertical figure that is roughly 16 kg. Mounting options are LB foot and FA flange plus I and Y rod knuckles, and the optional -S magnet enables CMSG, DMSG or EMSG switches.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X50 Is Used
High-speed anti-rotation transfer
The through-rod keeps the load from rotating while the variable air cushion at both ends allows fast 30-800 mm/s cycling with smooth stops, moving trays or parts between stations with about 527.8 N of push and pull.
Twin-load press with soft stop
Rod ends on both covers let the MGCD40X50 press or mark two workpieces at once, each seeing roughly 32 kgf of usable force, while the adjustable cushions decelerate the tooling gently at the end of the 50 mm stroke.
Rear-switch slide with flag
Use the rear rod end to carry a switch-actuating flag or mechanical stop while the front rod drives the slide; with the -S magnet and a CMSG or DMSG switch the cylinder reports both end positions.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD40X50 the Right Cylinder?
Choose the MGCD40X50 when you need equal force in both directions, anti-rotation and adjustable cushioning at both stroke ends in a compact 40 mm bore. At 527.8 N per side at 0.5 MPa it sits mid-range in the MGCD family: step down to bore 32 (345.6 N) for lighter duties or up to bore 50 (824.3 N) for heavier loads. If you need a double-rod cylinder at bores 20-40 without cushioning, the MGD with fixed bumpers is the alternative; if a single rod plus cushion is enough, pick the MGC. Standard strokes for this bore run to 500 mm, so the 50 mm stroke is a short-travel positioner. Specify the -S option if you plan to fit CMSG, DMSG or EMSG switches, and note the cushion decelerates the piston only: it is not a lock, so use an external rod lock or pilot check valve where the load must hold on air loss. For long strokes or side loads, add LB foot or FA flange mounting and an I or Y knuckle on the 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 MGCD Stainless Steel Mini Air Cylinder MGCD40X50 FAQ
Because it is a double rod cylinder, force is equal in both directions: 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa, with a theoretical maximum of 107.6 kgf at 1.0 MPa. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure is 1.5 MPa (215 psi), the fluid is air filtered to 40 um, temperature range is -20 to +70 C and speed is 30-800 mm/s.
The MGCD40X50 has a variable air cushion at both ends: you adjust the deceleration with the cushion needles for smooth stops at higher speeds or with heavier loads. It is not a fixed bumper pad (that is the MGD, a double-rod cylinder without cushioning) and not the MGC, which is a single-rod cushioned cylinder. The through-rod gives equal force both ways and anti-rotation. The optional -S magnet enables CMSG, DMSG or EMSG position switches.
