Air Chucks
& Shafts
|
Advantages
of Air Chucks and Shafts
- Pays for
itself in very little time due to decreased down time during roll
changes.
- No tools
necessary.
- Empty cores
remove instantly.
- Less chance
of telescoping rolls when placing roll on arbor.
- No parts
to remove or lose.
- Compensates
for wide variation of core inside diameters automatically.
- Eliminates
possibility of core damage.
- Drives equally
in both directions (accelerating and decelerating)
- Interchangeable
with any arbor mounted type chuck.
Unique Design
Features
- Fully expanding
periphery for maximum holding power.
- Leaves are
limited by "U" shaped restrainers in order to prevent over expansion
(inflation without a core does not damage bladder)
- Bladder is
fully protected by leaves and restrainers whether inflated or
deflated.
- Return springs
are provided to bring leaves back to minimum diameter when deflated.
- Large bladder
diameter produces maximum possible holding torque.

view of typical air chuck showing its cross section. This
view clearly shows the unique (patented) leaf locking design
which provides the best bladder protection of any chuck
presently available. |
This photo of a chuck with the leaves removed shows the new
(state-of-the-art) extended life bladder and the (patented)
interlocking clamps which seal the bladder to the chuck
body. |
