Product catalog summary

Technical Summary of Expanders and Components

1. Body Diameter and Number of Expanders

The document specifies configurations with 5 or 6 expanders. Body diameters mentioned include Ø69, Ø75, and Ø148, with options for special sizes.

2. Air Inlet Options

Air inlet configurations include a rear air inlet through the journal-end, allowing for different mounting and airflow arrangements.

3. Expander Types and Expansion Range

  • Linear Expanders: Made of rubber, capable of expansion ranges from +Ø4mm to +Ø9mm.
  • Segmented Expanders: Constructed from aluminum or special materials, designed for specific applications.

4. Construction Materials

  • Body and covers are primarily made from F-125 AISI 304 stainless steel or aluminum extrusion F-125.
  • Bushings are also made from F-125 AISI 304 or aluminum AISI 304, with special materials available upon request.

5. Machine Mounting and Bushings

Multiple mounting options for bushings are detailed, including flange-mounted and foot-mounted bushings for journal-ends of various diameters (Ø35 and Ø45) and lengths (long and short). These are compatible with body diameters Ø69, Ø75, and Ø148.

  • Flange-mounted bushings are available for both short and long journal-ends.
  • Foot-mounted bushings accommodate both short and long journal-ends across the specified diameters.

6. Additional Components

Rotary couplings and special components are mentioned, indicating customization possibilities for specific machine requirements.

7. Ordering and Customization

A checkbox order sheet is referenced, suggesting a structured process for selecting configurations and options.

Critical Information and Best Practices

  • Selection of expander type and material should align with the required expansion range and application environment.
  • Proper mounting and bushing selection are crucial for machine compatibility and operational reliability.
  • Special materials and configurations are available for customized needs, emphasizing the importance of specifying requirements clearly during ordering.

Cantilever shafts-2

axial displacementAgility and Productivity This type of expanding shafts is designed to streamline the loading and unloading process, similar to cantilever shafts, but with the added feature of being able to shift the expanding section of the shaft laterally to align the web of the coil. Anchored at only one end, the other remains free to load, unload, and manipulate the displacement knob. There are two models of axial displacement shafts: one with simple displacement and a second with a stationary knob displacement, which allows adjustment without stopping the machine. This design is aimed at...

Cantilever shafts-3

Custom body dimensions upon request: 0 25 mm to 0 300 mm Standard axial displacement range ± 15MM Simple Axial This is the basic model of expanding shaft with axial displacement. It has a knob that allows us to adjust the alignment of the expandable area. This knob is fixed to the rest of the shaft, so when the shaft rotates, the knob rotates as well. This requires axial displacement to be performed with the machine stopped or at very slow speeds to safely manipulate the knob. On the other hand, it is more compact due to its simpler mechanics.

Cantilever shafts-4

This is the most sophisticated model for regulating axial displacement. In addition to a knob, it includes a counter-knob that allows us to separate the knob from the shaft's rotation. By holding the counter-knob, the knob stops automatically regardless of the shaft's rotation. This feature allows material alignment adjustments to be made without stopping the machine, regardless of speed, increasing productivity and operator comfort.

Standard flange-mounted bushings, designed for pneumatic shafts of size 069 / 075, offer a reliable anchoring solution for cantilever shafts installed on machinery with vertical stands. These bushings are precisely machined from a single piece, ensuring exceptional performance in terms of rigidity and concentricity. By maximizing contact with the vertical stand, the wide flange surface provides optimal stability and precise alignment.

Standard flange-mounted bushings for shafts with a diameter of 0148 provide a reliable solution for anchoring cantilevered shafts in machinery with vertical beds. These bushings are precisely machined from a single piece, ensuring superior performance in terms of rigidity and concentricity. By maximizing contact with the vertical bed wall, the wide flange surface provides optimal stability and precise alignment.

The air expanding shaft selection table provides an overview of the stress calculation for the set consisting of the expandable shaft and the selected bushing. Key factors such as the weight and length of the coil and other relevant specifications influence it. The table is a valuable tool for easily selecting the correct model. For precise recommendations, consulting the technical team is advisable.
