Supply of spare parts and components for O&K machines, including legacy models no longer supported by OEM networks.
Overview
Ektennsa GmbH provides spare parts and technical components for O&K (Orenstein & Koppel) machinery used in mining and construction applications. The service focuses on legacy platforms and machine types that are no longer fully supported by original OEM supply structures.
Through structured sourcing, stock availability, and reproduction where required, we support the continued operation of O&K equipment in demanding industrial environments.

O&K machinery remains in operation across mining and heavy construction environments worldwide. As OEM supply structures have evolved or been discontinued, access to compatible spare parts requires specialized sourcing and technical verification.Components are specified according to original machine configuration, load requirements, and operational conditions to ensure compatibility and reliable performance.
