The pneumatic activation chuck (all forward) is for machines without rear cylinders (parallel lathes, adapters, dividing tables).
It is made of tempered steel and adjusted with a light alloy incorporated cylinder, mounted on bearings.
BE traction collets can be assembled (also cup type) for holding parts on the outside and expandable cusped collets for holding parts in an inner hole.
Closing the Mst chuck takes place through pneumatic action.
