About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X100S
The AirTAC MGCD50X100S is a double acting, double-rod JIS mini cylinder with a 50 mm bore and 100 mm stroke, built with a variable air cushion at both ends. Because a 20 mm rod exits both covers with the same M18x1.5 male thread, the piston sees the rod-side area in each direction, so the output force is equal both ways: about 824.3 N at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. The adjustable cushion decelerates the piston smoothly at each end of stroke, letting you run higher speeds or carry heavier loads without hard metal-to-metal stops.
The through-rod design also gives you anti-rotation guidance and a free rear rod end you can use for a position stop, a cam flag or a second load. The magnet fitted by the S code allows CMSG, DMSG or EMSG switches to be mounted for end-of-stroke signalling. Construction follows the JIS round-body footprint: a riveted SUS304 stainless barrel with hard-chrome plated rods, 1/4" ports, an operating range of 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), -20 to +70 C, and speeds of 30-800 mm/s. As a working rule, size your load at about 0.6 of the thrust: roughly 50 kg horizontal, or about 42 kg for a safe vertical lift on this 50 mm bore.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X100S Is Used
High-speed anti-rotation transfer
The through-rod keeps the workpiece from twisting while the variable air cushion absorbs the stop at 100 mm travel, letting the 50 mm bore cycle faster at 824.3 N per direction.
Twin-load press with soft stop
Rod ends on both covers each deliver about 824.3 N at 0.5 MPa, so two light pressing or staking points run from one cylinder, with the adjustable cushion easing the final approach.
Rear-switch positioning slide
The rear rod end drives a cam flag past the fitted CMSG/DMSG/EMSG switch while the front rod carries the load, giving a cushioned 100 mm slide with position feedback.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X100S the Right Cylinder?
Choose the MGCD50X100S when you need equal force in both directions, anti-rotation guidance and a controlled, cushioned stop at each end of a 100 mm stroke. At 824.3 N per side at 0.5 MPa it sits in the upper-mid force range of the MGCD family; step down to bore 32 or 40 for lighter loads, or up to bore 63 for the largest thrust. If you want a double-rod cylinder without adjustable cushioning in bores 20-40, the MGD with fixed bumpers is the alternative, and for a single-rod cushioned cylinder pick the MGC. Mount with the FA flange or LB foot, add I or Y rod knuckles on the rod ends, and note the fitted magnet already supports CMSG/DMSG/EMSG switches. Keep side loads off the rod on long strokes and guide external slides separately.

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 MGCD50X100S FAQ
This 50 mm bore double-rod cylinder delivers 824.3 N in each direction at 0.5 MPa and 1154 N at 0.7 MPa, with a theoretical maximum of 168.1 kgf at 1.0 MPa. It runs on filtered air at 0.15-1.0 MPa (22-145 psi), tolerates proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C at 30-800 mm/s, and uses 1/4" ports with M18x1.5 male rod threads on both ends.
The adjustable air cushion at both ends decelerates the piston near each end of stroke for smooth, high-speed stops; it is not a brake and will not hold position if air is lost, so add an external rod lock or pilot check valve for load holding. Unlike the MGD (double rod with fixed bumpers) or the single-rod MGC, the MGCD combines a through-rod with adjustable cushioning, and the fitted magnet on this -S model accepts CMSG, DMSG or EMSG switches.
