Pneumatic Chucks

Air adaptor
The fuel riser also can be written as an "inflated sleeve"
Use:
The gas riser sleeve is appropriate for the retracting of associated equipment such as coating, printing, rewinding, paper making, plastics, and many others. particularly in the case where the 3- or six-inch gas-growing shaft often makes use of mild load, it shows its superiority.  gas-stretching sleeves can be used instead of the six-inch air-up shaft, and the fine is mild and easy to update.
Structural features:
The fuel riser sleeve particularly comprises a the front sleeve, a rear sleeve, a cylinder body, an inner tube, an air bag, a convex keyboard etc.
The riser cloth is product of excessive nice aluminum and the floor is oxidized.
Ready with excessive exceptional airbags and brief inflation nozzles.
Good sealing effect, lengthy service lifestyles and convenient preservation.

Technique parameter

The inflatable sleeve combination can accept multiple loads and can be constructed in a variety of styles. Depending on the size of the device, it is also possible to use multiple expansion sleeves in series. When the coupling expander is overloaded, the joint effect will be lost and the equipment can be protected from damage.

  The inflatable sleeve has a long service life and high strength. The air expansion sleeve relies on the friction transmission, and there is no keyway weakening on the jointed parts, and there is no relative movement, and no wear occurs during work.

  The coupling expander is easy to disassemble and has excellent interchangeability. Because the expansion sleeve can combine the hubs of the larger cooperation gaps, and loosen the bolts when disassembling, the jointed parts can be simply disassembled.

  When the expansion is tight, the contact surface is tightly bonded and not rusted, and it is also easy to disassemble. Use the expansion sleeve to make the main parts and equipment simple. The machining of the shaft and bore of the expansion sleeve of the coupling device does not require high precision manufacturing tolerances like interference cooperation.

  There is no need to heat, cool or pressurize the air expansion device, just tighten the bolts to the required torque. And the adjustment is convenient, and the hub can be conveniently adjusted to the desired orientation on the shaft. The inflatable sleeve can also be used to join parts with poor weldability.
