The AirTAC AirTAC MA40X40SCA Mini Cylinder 40 mm Bore, 40 mm Stroke is a genuine double acting standard round-body mini air cylinder with a Ø40mm bore and 40mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service.
Compact push comes built in here: the AirTAC MA40X40SCA is a double-acting mini cylinder with a 40 mm bore and a 40 mm stroke, rated 628 N forward and 527 N on return at 0.5 MPa, climbing to 879 N at 0.7 MPa. Its riveted round body pairs a stainless-steel barrel with a hard-chrome plated 16 mm rod, so mild corrosion and washdown splash that would eat a painted-steel mini are non-events. Fixed anti-impact bumper pads soften both stroke ends; they decelerate the load but are not an adjustable air cushion. Size real work with real numbers: plan on roughly 377 N of continuous effort at 0.5 MPa, and expect the rod to hoist about 32 kg vertically once a 2:1 margin is applied against its 64 kg theoretical lift. Every unit carries a built-in magnet as standard, so a CMSG, DMSG or EMSG switch snaps on with no special-order piston, and the CA pivot back cover teams with an SDB pivot bracket for a swinging mount with no extra fabrication.

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.

A bench press station pushing small bushings into gearbox housings needs exactly the 628 N this 40 mm bore delivers at 0.5 MPa, with the short 40 mm stroke keeping cycle time tight.
On a bottling line, this cylinder swings a reject gate at up to 800 mm/s while the standard magnet and a CMSG switch confirm open and closed positions back to the PLC.
Raising a 30 kg test-rig lid vertically sits inside the 32 kg derated lift of this bore, and the CA pivot back cover lets the cylinder swing clear for loading.
A 32 mm bore from the same series musters 402 N at 0.5 MPa, so lighter clamping duties near that figure can drop a bore size and save compressed air; duties beyond 879 N at 0.7 MPa point to the MAC family 50 mm bore, which adds a variable cushion. Keep in mind the plain MA will not hold position once air is cut - the piston simply drifts - so add a rod lock or pilot check valve wherever a load must stay put. Bore 40 takes 1/8" ports with an M12x1.25 male rod thread; keep side loads off the rod by guiding them externally, and match the CA cover with FA flange or LB foot hardware when a fixed mount beats a pivot.
Quick checklist
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N; at 0.7 MPa those rise to 879.6 N and 738.9 N. The theoretical ceiling at 1.0 MPa is 128.1 kgf. It is double acting, runs on 0.15-1.0 MPa (22-145 psi) of filtered air at 30-800 mm/s, and carries fixed bumper pads rather than an adjustable cushion.
CA marks a pivot back cover, so the cylinder can hang on a pin and follow a swinging linkage - add the SDB pivot bracket to complete it. Where the machine prefers a rigid base, the FA flange or LB foot mounts bolt straight on, and I or Y rod knuckles handle the load-side joint. Air connections are 1/8" ports on this 40 mm bore.
