The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ40X175-40S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø40mm bore and 175mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
With a 40 mm wide trim window, the MAJ40X175-40S gives machine builders the most on-site latitude in this batch: the extend stroke can sit anywhere from 135 mm up to the full 175 mm. Force output is 628 N extending and 528 N retracting at 0.5 MPa, topping out near 880 N at 0.7 MPa. It runs on 0.15-1.0 MPa (22-145 psi) filtered air at 30-800 mm/s.
The body is a rolled stainless tube, not a tie-rod stack, so the compact round profile slips between guards where bulkier minis will not. Vertical duty math: 628 N balances roughly 64 kg, so with a 2:1 margin it lifts about 32 kg vertically. Keep side loads off the 16 mm rod and guide them externally on the long 175 mm travel.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

MA-family variants: MA / MAC (double acting ±cushion), MSA / MTA (single acting push / pull), MAD / MACD (double rod ±cushion), MAJ / MACJ (adjustable stroke ±cushion), MAR (cushioned with integrated F/U mount). Mounting accessories: FA flange, LB foot, SDB pivot; plus I and Y knuckles. Thread PT (blank) / G / NPT.

Ejecting pressed parts from a compact die where 628 N at 0.5 MPa kicks the part clear and the trimmed stop protects the die face.

Below it, a 32 mm bore yields 402 N at 0.5 MPa; above, nothing larger exists in the MA range, so 40 mm at 628 N is the ceiling for this mini family. Note the stop screw is an extend-side end stop only and will not hold a load if supply pressure drops. Pick FA flange or LB foot mounting; I and Y knuckles suit rod-end linkages. Because the magnet is built in as standard, CMSG / DMSG / EMSG switches need no option code.
Quick checklist
Yes: 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, and a theoretical peak of 128.1 kgf at 1.0 MPa. Air connection is 1/8"; rod thread is M12x1.25.
The rolled stainless barrel and hard-chrome plated rod shrug off condensation, light washdown and outdoor exposure that flake painted mini cylinders, while the riveted round construction keeps the footprint narrow in tight frames.
