HEVALOID®: Data sheet

Product catalog summary

Overview: The document provides technical specifications and guidelines for HEVALOID® Endless-Flat belts, which are length-stable and used for transmission and conveying purposes. It includes details on belt types, dimensions, tolerances, power transmission, and pulley design.

Specifications: The belts are available in various types (5005, 5065, 525 HF, 525, 535) with thicknesses ranging from 0.5 mm to 2.0 mm. They have a temperature resistance of -25 to 100°C and tensile strengths ranging from >800 N/cm to 3000 N/cm. The belts are made with a polyester fabric carcass and chloroprene rubber, offering antistatic and abrasion-resistant properties.

Dimensions and Tolerances: The belts come in lengths from 150 mm to 9000 mm, widths from 3 mm to 280 mm, and thicknesses from 0.5 mm to 2.0 mm. Tolerances for length, width, and thickness are +/- 0.5%, +/- 0.5 mm, and +/- 0.1 mm, respectively.

Power Transmission: The document provides a table showing the approximate power transmission capacity (kW/cm belt width) at various belt speeds (1 to 30 m/s) for different belt types. Pretension is recommended at 0.8 – 1.0%.

Pulley Design: For optimal performance, pulleys should have a smooth surface without rims and be properly crowned. The document provides recommended dimensions for pulley width, crown radius, and crown height for normal open drives.

Calculation Guidelines: Formulas are provided for calculating belt length for open and cross drives, as well as peripheral speed. Proper design ensures effective belt guidance and longevity.
