Features and Operation
- Alternating the supply and exhaust at the two cylinder ports drives extension and retraction.
- The tube and end-cover construction is not intended for dismantling. Protect the rod and sliding surfaces, and keep the load aligned with the cylinder axis.

Compatible Accessories and Sensors
| Accessory code |
Purpose and compatibility |
| F-MG40LB |
F-MG40LB: foot bracket for MG series, 40 mm bore. Optional; not implied by this model code. |
| F-MG40FA |
F-MG40FA: front flange for MG series, 40 mm bore. Optional; not implied by this model code. |
| F-MG40SDB |
F-MG40SDB: rear pivot bracket for MG series, 40 mm bore. Matches the mounting code selected in this model. The bracket is supplied with its matching pin. Requires the matching CB rear clevis; SDB alone is not the complete pivot connection. |
| F-MG40CB |
F-MG40CB: rear clevis for MG series, 40 mm bore. Optional; not implied by this model code. |
| F-ACQ32I |
F-ACQ32I: rod-end eye joint for MG series, 40 mm bore. Optional; not implied by this model code. |
| F-ACQ32Y |
F-ACQ32Y: rod-end fork joint for MG series, 40 mm bore. Optional; not implied by this model code. |
This MG40X200SDBT has no S magnetic-piston code. CMSG/DMSG magnetic detection is listed for the corresponding magnetic version, not for this nonmagnetic cylinder. Adding a sensor band does not add a piston magnet.
Cylinder-port connection matching
Match each 1/8 NPT cylinder port with an NPT fitting and the exact metric tube OD used in the circuit. PT and G threads do not mate directly with NPT, and similarly sized inch tubing is not interchangeable with the metric tubing in the circuit reference in this description.
If you choose an inch-tube circuit instead of the metric reference, order these NPT1/8 male options separately. Use either a connector or a controller at each port. Match the listed inch OD along the branch and at both tube ends; do not fit metric tubing to these inch sockets.

Straight connection: No speed adjustment
NPC5/32-1/8 (5/32 in), NPC1/4-1/8 (1/4 in), NPC5/16-1/8 (5/16 in), NPC3/8-1/8 (3/8 in)
-
Cylinder-port meter-out control: Speed adjustment
NPTL5/32-1/8A (5/32 in), NPTL1/4-1/8A (1/4 in), NPTL5/16-1/8A (5/16 in)
Type A restricts flow from the cylinder port to the tube; reverse flow is free. Maximum knob-rotation torque is 0.08 N·m, not thread-tightening torque.
Use soft nylon or polyurethane tubing. Fitting limits are 0–1 MPa and −20 to +70°C; stay within every connected part’s limits. Check tube insertion, thread sealing and clearance.
Weight Reference
1065.2 g — estimated configuration weight. Matched to the printed series, bore, stroke, cover and magnetic-option weight reference. The selected SDB mount adds an approximate 197.2 g based on its catalog plate envelope and steel density; holes and supplied fasteners are not individually weighed. Catalog weights and estimates are for reference only; actual product weight prevails.
Force Reference
Calculated theoretical force at 0.5 MPa: extension 628.0 N; retraction 527.5 N, using bore 40 mm and rod diameter 16 mm. This pressure × effective-area calculation excludes friction, acceleration and safety/load factors; it is not a guaranteed usable load. Check the actual operating pressure and mechanism load.

Series Ordering Reference
Standard strokes listed for this bore and operating variant: 10, 15, 20, 25, 30, 40, 50, 60, 75, 80, 100, 125, 150, 175, 200, 250, 300 mm. These are alternative order selections; they are not additional travel available from the current cylinder.
The catalog separately lists a long-stroke construction range of 301–500 mm. It is distinct from the standard-stroke list above; use the long-stroke dimensions and weights for that range. The separately printed maximum and permissible strokes are 500 and 800 mm respectively.
Select the operating variant, bore, stroke, magnetic option, rear-cover form, mounting accessory and pipe-thread option from the corresponding ordering chart. Do not transfer rear-cover or mount choices between single-rod, double-rod and adjustable-stroke versions without checking their dedicated row.
Selection, Installation and Use
- Select the bore and operating pressure from the required force, then check the stroke, moving load, speed, cushioning and mounting method for the mechanism.
- Flush the air lines before connection. Keep sealing tape or sealant clear of the first 1–2 thread turns and prevent water, particles or corrosive gases entering the cylinder.
- Keep the rod axis aligned with the load. Provide guides or supports where needed; avoid direct side loading and twisting of an unguided piston rod.
- Start speed adjustment with the flow-control valve closed and open it gradually. Meter-out control is the usual reference circuit; verify the actual single-acting or double-acting circuit.
- Factory-prelubricated cylinders can be used without additional lubrication. If a lubricator is used, the general instructions specify additive-free ISO VG32 turbine oil and continued lubrication.
- Isolate the air supply and exhaust residual pressure before servicing. Secure retained loads and prevent unexpected movement on restart. Protect against freezing, corrosion and strong external magnetic fields where magnetic sensing is used.
Circuit-selection reference at a theoretical 500 mm/s: for 40 mm bore the general catalog lists effective area 3.3 mm², valve examples 5V11006 / 5V12006, pneumatic-pilot alternatives 4A11006 / 4A12006, flow control PTL01, silencer BSL01, and tubing 8 mm OD × 5 mm ID. These are selection examples, not included components or a guaranteed installed speed; check actual port/thread adapters, pressure loss, tube length and load.
