The AirTAC Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ16X35-30S is a genuine double acting, adjustable stroke standard round-body mini air cylinder with a Ø16mm bore and 35mm stroke, M5×0.8 air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Where a machine builder wants maximum tuning freedom on a short stroke, the MAJ16X35-30S offers a 30 mm extend-trim window on a 16 mm bore and 35 mm nominal stroke - the stop screw can cut travel almost back to the bumper. Rated 100.5 N push at 0.5 MPa, it targets light gating, indexing and test positions.
The heterogeneous two-way piston seal traps grease inside the barrel, so the riveted stainless body runs long intervals without relubrication in dusty plant air. Treat 100.5 N as the ceiling: about 60 N of working force at 0.5 MPa keeps cycles crisp, equal to hoisting some 5 kg vertically with margin to spare. Sensors CMSG, DMSG and EMSG snap onto the standard-fit magnet.

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 | 101 N | 86 N |
| 0.7 MPa | 141 N | 121 N |
| Max (@1.0 MPa) | 21 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.
| MAJ | Standard round-body mini cylinder (adjustable-stroke). |
|---|---|
| 16 | Bore size in mm. |
| ×35 | Stroke length in mm. |
| -30 | Adjustable stroke window (mm the extend stroke can be shortened on site). |
| -S | Built-in magnet for CMSG / DMSG / EMSG sensors (standard on MA series). |
| CA / U / CM | Back-cover type: CA pivot, U flat-end, CM round-end. |
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.
Sets how deep an electrical probe tip reaches into a connector housing; the 30 mm range covers several housing heights.
Applies around 60 N at 0.5 MPa to verify a ribbon-cable crimp before the assembly passes downstream.
Gates pill trays between lanes, with a CMSG switch confirming the gate is fully seated.
There is no smaller MAJ bore, so if 100.5 N at 0.5 MPa is marginal, the next step is the 20 mm bore at 157.0 N push. The generous 30 mm window suits prototypes and multi-product fixtures where the extend stop is reset between changeovers. Remember the stop fixes the end of travel only; it will not pin the rod against drifting when supply pressure fails. Mount on an FA flange or LB foot, or hang I / Y knuckles on the 6 mm rod.
Quick checklist
Forces: 100.5 N push and 86.4 N pull at 0.5 MPa; 140.7 N push and 120.9 N pull at 0.7 MPa; 20.5 kgf theoretical maximum at 1.0 MPa. Pressure spans 0.15-1.0 MPa (22-145 psi), proof is 1.5 MPa (215 psi), speed 30-800 mm/s, port size M5x0.8.
The stainless tube with a hard-chrome plated rod resists corrosion in wet, food-wash or outdoor corners where painted minis fail, and the riveted round body stays slim behind crowded fixtures. The fixed bumper pads simply soften stroke-end impact; adjustable cushioning belongs to the MACJ family.
