The AirTAC AirTAC MBL50X175U Mini Cylinder | 50mm Bore 175mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 175mm 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 MBL50X175U is a double-acting aluminum mini round cylinder engineered for tight machine spaces where high thrust is still required. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa, utilizing a 175 mm stroke to move heavier jigs or workpieces. The U suffix denotes a rigid flat-end rear cover, providing a solid fixed mounting footprint for straightforward inline pushing tasks.
Inside this riveted rolling-packed barrel, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion. This specific SKU lacks the -S magnet option, meaning it cannot be fitted with a CMSG, DMSG, or EMSG position sensor. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion.

Pushes heavy steel bar stock through a spindle bushing using 981 N of force, where the 175 mm stroke provides sufficient travel to index the material accurately.
Folds cardboard end flaps on heavy product pallets in a compact packaging line, utilizing the rigid U flat-end mount to maintain a fixed pushing angle.
Diverts faulty glass beverage bottles off a high-speed conveyor belt, using the 0.15-1.0 MPa operating range to handle varying container weights.
If 981 N at 0.5 MPa is more force than your assembly requires, stepping down to the 40 mm bore drops the push force to 628 N and saves envelope space. Conversely, if your load demands more thrust, stepping up to the 63 mm bore increases the push force to 1558 N. Because the U back cover is rigid, this cylinder is ideal for straight-line actuation; if your mechanism requires angular movement, select a CA pivot cover instead. To replace this unit, match the 50 mm bore, 175 mm stroke, G1/4 port, PT thread, U flat-end back cover, and no magnet.
With a 175 mm stroke on a mini round body, the unsupported Ø16 mm rod is susceptible to bending under side loads. For this length, you should use an external guide rail, pair the cylinder with a pivot mounting accessory, or consider the MBLD double-rod variant to prevent rod bearing wear. Remember that the fixed rubber bumper only softens end-of-stroke impacts; this cylinder will not hold a load if air pressure is lost, so add an external rod lock for vertical applications.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push force and 881 N pull force. At 0.7 MPa, the push force increases to 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. The operational speed range is 30-800 mm/s.
No, the base MBL50X175U uses a fixed rubber bumper to absorb end-of-stroke impacts and does not feature an adjustable cushion screw. If your application requires adjustable air cushioning for heavier loads or faster speeds, you should select the MBLC variant instead.
