About the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-100S
Reach 175 mm and stop anywhere within a 100 mm window: the MAJ25X175-100S is double-acting, so air both extends and retracts the 10 mm hard-chrome rod, and the external stop screw sets the extend limit on site during commissioning. At 0.5 MPa the 25 mm bore develops 245.3 N of push force.
Fixed anti-impact bumper pads decelerate the piston at stroke ends, cutting noise and metal-on-metal hammering - note they are passive pads, not adjustable air cushions (that feature belongs to the MAC family). The riveted stainless round body is compact and corrosion-tolerant. The 245.3 N push works out to roughly 25 kg; halved for a 2:1 margin, expect about 12.5 kg of vertical lift at 0.5 MPa.

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.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-100S Is Used
Deep-draw parts kickers
Push deep-drawn cups out of a die pocket at up to 175 mm depth, trimming the extend stop inside the 100 mm window to suit different cup heights.
Custom test rigs
Drive a probe or weight stack in a benchtop endurance rig where the stop screw sets a repeatable end position across a wide 100 mm tuning range.
Palletizer nudging arms
Nudge cartons square on the pallet infeed; 245.3 N at 0.5 MPa squares light loads and the bumper pads quiet the 175 mm stroke ends.
Is the Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-100S the Right Cylinder?
Compare bores before buying: the 20 mm size offers 157.0 N at 0.5 MPa and the 32 mm size 402.2 N, so pick 25 mm for mid-range push on a long 175 mm stroke. Long strokes amplify side load, so guide the tooling and keep the load in line with the M10x1.25 rod thread. The adjuster is a hard end stop for the extend direction only - under air loss the piston drifts, so add a separate locking valve if you must hold position. FA flange or LB foot mounting; I and Y rod knuckles are available (no SDB code on adjustable models). The built-in magnet works with CMSG / DMSG / EMSG switches as shipped.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
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 Bumper models: keep speed within the rated range.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAJ Double Rod Adjustable Stainless Steel Mini Cylinder MAJ25X175-100S FAQ
The 25 mm bore yields 245.3 N push and 206.1 N pull at 0.5 MPa; push climbs to 343.4 N at 0.7 MPa and the theoretical peak at 1.0 MPa is 50 kgf. Supply air filtered to 40 um within 0.15-1.0 MPa (22-145 psi).
The high-precision stainless tube is rolled onto aluminium covers with a stainless block - a riveted build that stays compact and shrugs off mild corrosion and washdown better than painted-steel minis. Ports are 1/8" on this 25 mm bore and the rod thread is M10x1.25.
