Product advantages

At Bando we recognized the excellent qualities of the Flat Belt and we refined those qualities resulting in a next generation Flat Belt with further improved transmission capability:

  • An operation with ideal tension and improved transmission efficiency leads to energy saving and CO2 reduction.
  • Maintenance free is possible due to the longer service life and tension control by the auto-tensioner.
  • Because of the thin belt construction the flex distortion is very low.
  • Compact layouts are possible because the reverse bending has no influence on the durability.

Product concept

Also we developed a meandering control and prevention device that autonomously controls the belt running position. By combining that device with an auto-tensioner technology we overcame the belt side tracking and tension problems.

We hope that you will use our next generation energy saving power transmission product for your machines and applications.


HFD-Flat Belt System

The Flat Belt is constructed of long approved EPDM rubber.

HFD System Overview en

The flat belt only requires one third of height compared to V-belts. The compact belt design offers larger wrap-around angles and equal or lower pre-tension, which offers high performance power transmission.

Automatic tension and meandering device

By installing the automatic tension and meandering device an autonomous control system for the flat belt and pulley is realized. Thereby a maintenance free system is created. The tension pulley is fixed in Point A (Pivot Point) and the requested tension adjustment can be done by the elongated hole in Point B. After the positions A and B are fixed, the device can operate as a self-control tension and meandering system.
