The AirTAC AirTAC MBL63X150SCA Mini Cylinder | 63mm Bore 150mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 150mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL63X150SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces where high force is still required. Operating at 0.5 MPa, it provides 1558 N of push force and 1457 N of pull force, making this 63 mm bore, 150 mm stroke unit ideal for driving heavier small-part tooling. The body features a riveted rolling-packed aluminum barrel that crimps the covers directly to the tube, yielding a lightweight footprint that is not designed to be disassembled like a tie-rod cylinder.
This SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, or EMSG sensor switches to track rod position. It uses a carbon-steel piston rod with a 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for long service life. The rear end is a CA pivot (clevis) cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable cushion.

Provides 1558 N of push at 0.5 MPa to knock small stamped metal parts out of progressive dies, where the CA pivot rear absorbs die-misalignment stress.
Swings a diverter arm on a packaging line conveyor; the 150 mm stroke moves small cartons laterally while the clevis mount handles the arcing load path.
Drives an upper test head down onto printed circuit boards, using the -S magnet and a DMSG solid-state switch to signal the control system when the head is fully lowered.
This 63 mm bore is the largest standard MBL size, delivering 1558 N push at 0.5 MPa. If you need less force to save space, step down to the 50 mm bore, which provides 981 N of push force at 0.5 MPa. Because this is the top of the range, there is no larger MBL bore; for even higher loads, consider moving to an ISO 15552 profile cylinder. If your application needs end-of-stroke speed control for heavier moving masses, step up to the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion.
With a 150 mm stroke, side-load stress on the 16 mm rod is moderate, but the CA pivot back cover on this specific SKU is highly beneficial as it allows the body to articulate and prevents rod-bearing binding under slight misalignment. For purely rigid linear pushes, the U flat-end cover is preferred. Note that this cylinder does not hold its load if air pressure is lost or the valve is centered; the rod will drift. Use an external pilot-operated check valve or rod lock if position must be maintained without live pressure.
Quick checklist
This 63 mm bore cylinder provides 1558 N push and 1457 N pull at 0.5 MPa, 2181 N push at 0.7 MPa, and a maximum theoretical force of 318 kgf at 1.0 MPa. The -S suffix indicates a built-in magnet compatible with AirTAC CMSG (reed), DMSG, and EMSG (electronic) sensor switches.
The base MBL uses a fixed rubber bumper at the end of stroke to soften impact, which cannot be adjusted for speed. If your application requires deceleration control for heavy moving loads, the MBLC variant offers an adjustable air cushion. The bumper is not a braking lock, so the rod will drift if air pressure is removed.
