• All international and domestic production locations work uniformly according to Total Quality Management (see “Certificates”).
  • In the Optibelt research laboratory, the materials are tested under the hardest conditions.
  • Suppliers are chosen according to quality, not according to price criteria.
  • The sales department maintains constant informational exchange with our customers. In this way, our developers can react promptly to the needs of the market.
  • We invest in bright minds: The ideas of our employees represent our innovation pool.

Success proves us right: With extremely low manufacturing tolerances, Optibelt high performance drive belts set standards. We are especially proud of this because every charge of the natural product, rubber – the main component of our drive belts –, is composed of slightly different properties.
