The AirTAC AirTAC MBL63X30U Mini Cylinder | 63mm Bore 30mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm bore and 30mm 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 MBL63X30U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, making it the highest thrust class in the MBL family. The 30 mm stroke provides rapid, short-travel actuation. As a U-type variant, it features a rigid flat-end rear cover for direct fixed mounting.
This model uses a riveted rolling-packed aluminum barrel that crimps the front and back covers directly to the tube, ensuring a lightweight yet durable construction that is not designed to be disassembled like a tie-rod cylinder. The carbon-steel piston rod features a 20 um hard-chrome plating for superior wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains grease for extended operational life. Because this SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Provides 1558 N of push force at 0.5 MPa to eject plastic parts from tight mold cavities where a larger ISO 15552 cylinder would not fit.
Acts as a rigid stop block for heavy pallets on a 30 mm stroke, using its U flat-end rear for direct mounting to the conveyor frame.
Delivers up to 318 kgf of theoretical force at 1.0 MPa to flatten rivets in sheet metal assembly jigs within confined workspaces.
At the top of the MBL range, the 63 mm bore provides maximum thrust. If you need less force to prevent damaging delicate parts, step down to the 50 mm bore, which yields 981 N of push force at 0.5 MPa. If you require faster cycling with heavier end-loads, consider the MBLC variant, which replaces the base MBL's fixed rubber bumper with an adjustable air cushion.
The fixed rubber bumper softens end-of-stroke impact but does not lock the rod; if air pressure drops, the rod will drift and the load will drop, so an external rod lock or pilot-operated check valve is required for position holding. This MBL63X30U uses a G1/4 port, PT thread form, U flat-end back cover, and no magnet. Replacement parts must match these exact specifications.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force is 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If you need adjustable air cushioning for heavier moving masses, choose the MBLC variant.
