Sunrise Group (Dongguan) Industrial Co., Ltd is an enterprise focusing on the design and quality of the products like air expanding core chucks. Our design team is composed by a master designer who has the responsibility to make decisions about the way the creative process should evolve, and a number of technical designers specialized in the industry for years. We also employ the industry experts to dominate the production process from materials selection, processing, quality control, to quality inspection.
Sunrise products are well-received at home and abroad for the stable and reliable quality and the vast diversity. Most clients have achieved significant growth in sales and now hold a positive attitude toward the market potential of these products. What’s more, the relatively low price also gives clients a rather competitive edge. Therefore, there are more and more clients coming for further cooperation.
We guarantee the products at SUNRISE including air expanding core chucks enjoy warranty. If any problem occurs under normal use, contact us immediately. We will arrange professional technicians to help solve the problems efficiently.
A safety chuck is a specialized quick coupling used for web handling operations. In order to maintain the expected tension in a web, a shaft from which a roll is being unwound must be subject to a constant level of torque from a tension brake. Similarly, a shaft onto which a roll is being wound must be subject to a constant level of torque from a motor through a slip / tension clutch. A safety chuck provides a means to transmit torque to a roll shaft as well as the ability to switch the roll shafts quickly and conveniently. Unlike most couplings, a safety chuck does not require loosening and tightening of screws or moving any component other than the shaft and the chuck itself. Tension clutches, brakes, and motors need not be moved or dismounted.
When a locking collar or handwheel of both safety chucks are rotated to zero degree, they can be tilted back (away from the roll), and the roll can be lifted out vertically. A new roll is placed in vertically and the handwheels are tilted closed to the original position. The handwheels will start to close automatically if rotated past a few degrees (this is the safety aspect of a safety chuck..
The pressure supply is fed into the cylinder via a flexible tube.
Positive disengagement is achieved by the use of return springs.
Features
¡ôSealed cylinder ensures low air consumption.
¡ôTorques can be varied by regulating the supply pressure.
¡ôSpeed of engagement can be controlled by varying the supply flow rate.
¡ôSingle friction face design virtually eliminates drag torque
¡ôAxial thrusts are contained within the units.

Expanding Core Shafts
For high speed and/or heavyweight applications requiring maximum torque capacity and minimum vibration.Mechanical design provides the most powerful gripping force possible.Activated by turning a crank (or impact wrench) that is inserted into the end of a journal.Requires just five cranks for full expansion ¨C lugs rise concentrically to center the carbon fiber shaft in the core, minimizing the roll bounce common with other types of expanding shafts.Mechanical and Pneumatic/Mechanical Shafts are also available in Double E's traditional steel design.
We manufacture to your specifications to suit your equipment, including cantilevered or custom designs. The SUNRISE Leaf Style air expanding shafts are guaranteed for one year against material and workmanship defects.
