Overview of Seamless Steel Belts

The document details the features, specifications, and applications of seamless steel belts used in conveyor systems and industrial processes. These belts are designed for high precision, durability, and resistance to corrosion and fatigue.

Key Features

  • No Slip and Stable Operation: The belts maintain tension without slipping, even when driven by a crown pulley, ensuring consistent performance.
  • Fatigue Strength: The belts exhibit high fatigue resistance, critical for long-term reliability under cyclic loading.
  • Material Quality: Made primarily from stainless steel grades such as SUS304, SUS301, SUS631, and 157PH, with options for titanium and carbon steel.
  • Surface Treatments: Options include silicone rubber lining, polyurethane coatings, and super mirror finishes to enhance grip, reduce wear, and improve cleanliness.
  • Precision Manufacturing: Utilizes advanced rolling and electro-trimming processes to produce super-thin seamless tubes and belts with tight dimensional tolerances.

Specifications and Dimensions

The belts are available in various thicknesses ranging from 0.05 mm to 0.12 mm and widths up to 4000 mm. Pulley diameters and belt thicknesses are matched to ensure optimal performance, with typical pulley diameters calculated as belt thickness multiplied by 700.

Production and Quality Control

  • Production involves strict material selection, welding, and finishing processes to ensure corrosion resistance and mechanical strength.
  • Quality control includes vibration analysis using spectrum analyzers and surface roughness measurements to maintain high standards.
  • Perforated and super mirror surfaced belts are produced using high-precision punching and finishing technologies.

Applications

  • Conveyor systems in clean rooms and chemical processing environments.
  • Belt cutter saws and heat sealers requiring precise and durable belts.
  • Winding shutters and other industrial machinery where stable belt operation is critical.
  • Specialized applications requiring corrosion resistance and high tensile strength.

Ordering and Customization

Customers can specify belt dimensions, materials, surface treatments, and pulley configurations. The company offers design support for steel conveyor belt systems tailored to specific objects and processes.

Recommendations and Best Practices

  • Use stainless steel belts for environments requiring corrosion resistance.
  • Match pulley diameter to belt thickness to avoid premature wear.
  • Employ vibration analysis and surface roughness testing for maintenance and quality assurance.
  • Consider surface coatings like silicone or polyurethane for improved grip and durability.

Limitations and Considerations

  • Perforations in belts can lead to contamination if not properly managed.
  • Soft or wet objects on the belt surface should be removed carefully to avoid damage.
  • Welding and finishing processes must be carefully controlled to maintain belt integrity.

Summary

This document provides comprehensive technical information on seamless steel belts, emphasizing their construction, material properties, manufacturing processes, and applications. It highlights the importance of precision engineering and quality control to achieve high-performance conveyor belts suitable for demanding industrial environments.

Features of the seamless belt Physical Our technology of heat treatment ana characteristic railing can produce better Quality. By controlling the friction coefficient, the tension. and the belt winding angle, the belt will not slip. Using a crown pulley, the belt will stay centered while being driven. 3. High fatigue resistance Even when the belt is relatively thick, relatively smalt diameter pulleys can drive the belt. The belt edges are rounded during trie rolling processes. This shape is advantageous since it Is not damaged by repeated compression and expansion on the pulleys. 4. Withstands...

* All components including the belt and frame are made of stainless steel, in a compact size. * Since stainless steel belts do not wander, the edges do not become worn or cracked. * Both the frame and belt can be washed in water, to keep them hygienic. * The belt never elongates or shrinks while running. * The belt surface is very hard and difficult to scratch, easy to accumulate. * This type of conveyor generates very little * This conveyor can feed objects cooled to as low * The objects on the belt cannot become contaminated with metat particles since the belt does not produce metal particles....
