Products and services

optibelt RBK elastic

Elastic ribbed belts transfer torque in drive systems without the need for tension idlers. The elastic tension cord in the ribbed belt ensures automatic tension throughout the entire service life of the belt. As a rule, elastic ribbed belts are used for the mid-range performance bracket and fixed center distances.

New engine design is putting an increasing emphasis on space saving. Small pulley diameters necessitating thin, flexible belts are often the result.
OPTIBELT ribbed belts are ideal products for today’s serpentine drives and operate all of the accessories quietly and smoothly.
In passenger cars, commercial vehicles and buses, OPTIBELT ribbed belts drive the ancillaries such as the generator, the air conditioning compressor, the power steering pump smoothly and quietly.

optibelt ZRK

Optimum power transmission even after thousands of operating hours and with extreme loads – for these high requirements, OPTIBELT developed the ZRK timing belt.

The sections and belt constructions of this high capacity belt have been perfectly designed – down to the smallest detail.

The materials used are also perfect for the job: wear-resistant polyamide, zero stretch glass fibre cord and durable polychloroprene elastomer.

News & Innovations

optibelt RBK SCC 

The world’s first ribbed belt with change indicator: the optibelt RBK SCC – SECURED CHANGE CONTROL.
Every motor is affected by an individual range of factors: humidity, cleaning agents, heat and cold are just a few examples. At the same time, the ribbed belt now also plays an increasingly important role in today’s cars and vans. More and more auxiliary units, and therefore also more safety-related systems, are now driven with the help of the ribbed belt and its components.
With today’s quality products, made to the highest standards with materials such as EPDM (ethylene propylene diene monomer rubber), it is impossible to reliably check the actual wear and tear of a ribbed belt without the use of tools. This means that the wear limit can be exceeded without anyone noticing, and nothing can be done to prevent this.
The optibelt RBK SCC provides the solution: Red markings become visible on the ribbed side of the belt when the belt reaches the end of its service life. OPTIBELT recommends that you have the ribbed belt serviced and, if necessary, replaced.

This innovation was highly acclaimed at the “International Grands Prix for Automotive Innovation” at the EQUIP AUTO 2015 exhibition in Paris. The SCC belt received the Silver Trophy in the “Spare parts & aftermarket” category. The jury, comprising 60 journalists from specialist magazines, chose the winners from several hundred nominees.
