About the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X50S
The AirTAC MGCD50X50S is a double acting, double-rod JIS mini cylinder with a 50 mm bore and 50 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 either direction, so output 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 travel, letting this cylinder run at higher speeds or carry heavier loads than an unbuffered equivalent, while the through-rod resists rotation and gives you a rear rod end for a stop flag or a second load. A practical rule of thumb for sizing: halve the 0.5 MPa force figure, which leaves roughly 42 kg as a safe vertical load for this model.
Construction follows the JIS round-body mini format: a riveted SUS304 stainless barrel with hard-chrome plated carbon-steel rods and two-way lubricant-storing piston seals. It runs on air filtered to 40 um at 0.15-1.0 MPa (22-145 psi), tolerates a proof pressure of 1.5 MPa (215 psi), operates from -20 to +70 C, and covers speeds of 30-800 mm/s. Air ports are 1/4". The S code in MGCD50X50S means a magnet is fitted, so CMSG, DMSG or EMSG switches can be clipped on for end-of-stroke sensing. Mounting options are FA flange or LB foot, with I and Y rod knuckles available; note that the cushion decelerates the stroke ends only and does not lock the load, so use an external rod lock or pilot check valve where position must hold on air loss.

Where the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X50S Is Used
High-speed anti-rotation transfer
The double rod keeps the load from twisting while the variable air cushion brakes each end, so the MGCD50X50S can shuttle trays or pallets at up to 800 mm/s without hard stops or end-of-stroke bounce.
Twin-load press with soft stop
With 824.3 N available in both directions at 0.5 MPa, the front rod can press a light part while the rear rod drives a flag or second fixture, and the adjustable cushion gives a gentle landing on both ends.
Rear-switch slide positioning
The fitted magnet accepts CMSG, DMSG or EMSG switches at both rod ends, so the 50 mm stroke can be confirmed electrically while the cushion absorbs the stop and the through-rod holds alignment.
Is the Airtac MGCD Stainless Steel Mini Air Cylinder MGCD50X50S the Right Cylinder?
Size the MGCD50X50S by force, not bore: at 824.3 N per direction at 0.5 MPa it sits in the upper-middle of the MGCD range, below the 63 mm bore (1400.9 N) and above the 40 mm (527.8 N). Choose it when you need equal push and pull in a compact round body, smooth adjustable deceleration at both stroke ends, and anti-rotation from the through-rod. If you need a double-rod cylinder at 20-40 mm bore without cushioning, the MGD with fixed bumpers is the lighter option; if a single rod with a cushion is enough, step to the MGC. Mount with the FA flange or LB foot, add an I or Y knuckle for rod-side articulation, and order the -S suffix (as here) only if you will fit CMSG, DMSG or EMSG switches. Standard strokes for the 50 mm bore run to 500 mm; for strokes beyond that, confirm application side-loading and consider external guides.

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 MGCD50X50S FAQ
It is a double acting, double-rod JIS mini cylinder, 50 mm bore and 50 mm stroke, with a 20 mm rod and M18x1.5 male thread on both ends and 1/4" air ports. Output is equal both ways: 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. Operating pressure is 0.15-1.0 MPa (22-145 psi), proof pressure 1.5 MPa (215 psi), temperature range -20 to +70 C, and speed 30-800 mm/s on air filtered to 40 um. The barrel is SUS304 stainless with hard-chrome plated rods.
The cushion is an adjustable air brake at both stroke ends: you tune it to decelerate the piston smoothly, which permits higher speeds and heavier loads than an unbuffered cylinder. It only slows the piston near the ends; it is not a lock, so fit an external rod lock or pilot check valve if the load must hold on air loss. Unlike the MGD, which is a double-rod cylinder with fixed bumper pads, the MGCD has adjustable air cushioning. Unlike the single-rod MGC, the MGCD's rod exits both covers, so force is equal in both directions and the rear rod end can carry a stop flag or second load. The fitted magnet also allows CMSG, DMSG or EMSG position switches.
