Under Extreme
Conditions

OPTIBELT has the right ribbed V-belts for every type of environment and every drive geometry. Even at extreme temperatures and harsh weather conditions, you can rely on our optibelt RBK made of EPDM: it delivers optimal performance within a temperature range from –40 to +130°. This is so that passenger cars and lorries reliably start after standing for a long time at low temperatures in the winter.


  • Extreme performance and optimal cost effectiveness – because downtime is not an option at any time of the year.

  • Reliable in extreme situations: even at 130°C, the optibelt RBK made from EPDM does not reach its limits.
