The AirTAC Airtac MTI Single Acting Stainless Steel Mini Cylinder MTI32X15R is a genuine single acting, pull (spring return) round-body mini air cylinder with a Ø32mm bore and 15mm stroke, 1/4" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Delivering 295.6 N of pull force at 0.5 MPa, this AirTAC round-body mini cylinder is built for tasks that need robust tension. The MTI32X15R is a single-acting PULL type: filtered air retracts the rod while an internal spring extends it. Because it rests in the extended position, the rod stays forward during an air loss, acting as a fail-safe hold or normally-engaged stop. The fixed TPU bumpers soften the end of stroke without locking the load mid-travel.
The stainless-steel barrel and rod resist mild corrosion and washdown environments. It requires at least 0.2 MPa of air pressure to overcome the spring and retract. This SKU lacks a magnet and cannot take a sensor; adding the -S variant enables CMSG, DMSG, or EMSG switches. It features a 1/4" port, an M10x1.25 male rod thread, and an R axial-in rear cover. For sizing, it offers a safe working load of about 177 N, or a vertical pull of roughly 15 kg with a 2:1 margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
| Pressure | Pull force (spring return) |
|---|---|
| 0.5 MPa | 295.6 N |
| 0.7 MPa | 388.8 N |
Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.
| MTI | round-body mini cylinder (single-acting pull, spring-return). |

| 32 | Bore size in mm. |
| ×15 | Stroke length in mm. |
| -S | Optional built-in magnet for CMSG / DMSG / EMSG sensors. |
MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Keeps a 15 kg workpiece clamped under spring pressure. Air retracts the clamp to load the part, and it stays engaged if air pressure drops.
Acts as a heavy conveyor stop that rests extended to halt pallets. A 0.2 MPa air signal pulls the 12 mm rod back to release the flow.
Pulls webbing or belts with up to 177 N of safe working load. The spring maintains baseline tension at rest without consuming air.
Size this actuator strictly by its pull force. If 295.6 N at 0.5 MPa is too much, step down to the Ø25 bore, which provides 151.1 N. If you need more retract strength, the Ø40 bore yields 466.8 N. Remember that the spring limits standard single-acting travel to 80 mm for this bore; this 15 mm stroke is well within that range. You must supply at least 0.2 MPa to beat the spring and pull the rod back. Mounting options include LB foot, FA flange, SDB pivot-block, and TC trunnion. Because this specific SKU has no magnet, you cannot mount position sensors; select the -S version if you need CMSG, DMSG, or EMSG switches.
Quick checklist
It provides 295.6 N of pull force at 0.5 MPa and 388.8 N at 0.7 MPa. It needs at least 0.2 MPa to overcome the internal spring. The rod is normally extended at rest, so it stays forward on air loss.
No, this SKU lacks a magnet and cannot take a position switch. You must choose the -S variant to use CMSG, DMSG, or EMSG sensors. It is a single-acting pull cylinder, not double-acting.
