The ribbed belt combines the high flexibility of the flat belt with the high performance of the V-belt. The V-shaped parallel ribs are made from a wear-resistant rubber compound. The high strength tension cord is designed for the many applications of the ribbed belt.

It is embedded in a rubber adhesive mixture and covers the entire width of the ribbed belt. Fibre reinforced, wear resistant rubber compounds ensure quiet operation, oil and heat resistance and a long belt life.

The small minimum pulley diameters are suitable for drives with high speed ratios as well as slow running drives. Ribbed belts are well suited for the use of back bend idlers, such as in serpentine drives.

The optibelt OMEGA RB timing belt with an additional PK ribbed belt profile on the top surface of the belt is perfect for use in mills, such as food, cereals, fruit and flour mills, where the drive pulley direction on the top surface is reversible and slip is necessary if the drive jams.

Elastic ribbed belt sections EPH and EPJ consist of:

The superstructure is made from a fibre-reinforced rubber mixture. The fibres are laid perpendicular to the direction of belt travel and stabilise the belt during dynamic operation.

The tension cord is a high modulus polyamide material embedded in a rubber compound and covers the entire width of the ribbed belt.

The rib compound is characterised by high wear resistance and damping properties.

The elastic ribbed belts were especially developed to meet the mechanical requirements for fixed distances between centres. The unique tension cords of high-quality polyamide provide the required elasticity for the ribbed belt and consequently also increase the permanent resistance even with frequent start/stop cycles.

Elastic ribbed belts of the optibelt CONVEYOR POWER RB series are used in all fields of the transport and logistics industry. Straight roller track conveyors – curved conveyors – accumulating conveyors – continuous conveyors – sorters – transfer lines – outfeed & infeed systems, semi-automatic & fully automatic storage systems, etc.

With an efficiency of up to 97%*, the optibelt CONVEYOR POWER is used with transport weights of 1 – 1200 kg depending on the conveying speed and acceleration. The optibelt CONVEYOR POWER was also further optimised for use in curved conveyors.

Ribbed belts unite the great flexibility of the flat belt with the high performance of the V-belt.

Abrasion-proof rubber components allow for smooth running, a degree of oil and heat resistance and a long operational life.

Ribbed belts are suitable for using back bend idlers which are, for example, in serpentine drives.
