SMC MGP Compact Guide Cylinder with End Lock
SMC MGP Compact Guide slide-bearing cylinders with End Lock (that holds the cylinder in position, even if the air supply is diskonnected), offer mounting points on the top, side, or bottom (and a T-slot mount option), with pneumatic ports on the top or side. CQM double-acting cylinders are non-rotatable, offer a high resistance to side loads, and are able to withstand lateral loading forces that are more than twice the force experienced by conventional stopper cylinders. SMC MGP cylinders with End Lock are suitable for conveyor line stopping, lifting, positioning, or push-off applications.
