Advantages of Air Shafts and Chucks

Advantages of Air Shafts and Chucks

1. Pays for itself in very little time due to decreased down time during roll changes.
2. No tools necessary.
3. Empty cores remove instantly.
4. Less chance of telescoping rolls when placing roll on arbor.
5. No parts to remove or lose.
6. Compensates for wide variation of core inside diameters automatically.
7. Eliminates possibility of core damage.
8. Drives equally in both directions (accelerating and decelerating)
9. Interchangeable with any arbor mounted type chuck.

Unique Design Features

1. Fully expanded periphery for maximum holding power.
2. Leaves are limited by "U" shaped restrainers in order to prevent over expansion (inflation without a core does not damage bladder)
3. Bladder is fully protected by leaves and restrainers whether inflated or deflated.
4. Return springs are provided to bring leaves back to minimum diameter when deflated.
5. Large bladder diameter produces maximum possible holding torque.

Features

1. Only 0.0625" (1.5mm) difference between core & shaft diameters. Thus a 3" (76mm) core chuck has a 0.0625" (1.5mm) max. I.D. for shaft insertion.
2. Long, maintenance-free operation since contact with the core I.D. is made with wear-resistant aluminum gripping leaves.
3. Greater gripping pressure, which is achieved through the combination of the spiral-wound tubing and gripping leaves.
4. Minimum down-time since the rubber tubing size is standard on all size chucks, is available in our factory that requires only few minutes for replacement
5. Deflated Diameter = .0625" (1.5mm) under nominal core size Inflated Diameter = .1875" (4.7mm) over nominal core size

Unique Benefits

1. Positive locking over the full core length.
2. Greater gripping pressure.
3. No core damage due to reaming ... less down-time for roll changes.
4. Virtually maintenance-free operation ... aluminum locking leaves resist wear.
5. Minimum down-time ... standardized rubber tubing available easily attached to air valve ... can be replaced in minutes.

SATGURU'S shafts and chucks require only 50-80psi input to fully inflate.
