Hydraulic Expanding Holding Devices

Precision Positive Centering

Jerry Tools holding devices conform to the chucking surface of the part. They completely fill the inside diameter. Hydraulic arbors expand into holes that are bell-mouthed, tapered, and out-of-round and locate the true centerline of the part.



Complete Machine Adaptability

Jerry Tools arbors and chucks adapt to any machine spindle, adapter plate or face plate through precision hydraulics. Precision split-sleeve adapters are used with Jerry Tools hydraulic expanding arbors ... by using one arbor and several sleeves, more parts with different inside diameters can be held with one basic arbor.



Precision Split-sleeve Adapters

Split sleeves are used with hydraulic expanding arbors or chucks. By using one hydraulic tool and several sleeves, more parts with different inside diameters can be held with one basic arbor or chuck.
