The unique SKF G-ECOPUR seals in the toughest environments

SKF South Africa’s Sealing Division recently presented a unique sealing system, the world-renowned G-Ecopur, to a global rock boring and drilling service provider. This innovative large size machined seal solution has optimised boring and drilling equipment reliability and service life, subsequently boosting productivity and production volumes. The turnkey solution also provides the end-user with access to SKF’s professional technical support services. 

The company required a high-quality sealing solution in the form of a new seal design for their rock boring equipment, prompting them to approach SKF South Africa. Tunnel boring and hard rock face mining is one of the most challenging operations and the equipment used in this harsh environment takes a beating. 

Andre Weyers, SKF Product Manager: Seals, explains how SKF gained tremendous experience with seal solutions for this particular application. “During the development of a new prototype tunnel boring machine, SKF became very involved in developing the unit’s challenging sealing arrangement. The sealing system has to be able to withstand very high contaminants and pressures. We also had to address the challenge of large seal sizes. This gave rise to the G-Ecopur which is specially designed to overcome these exact challenges. After careful assessment of the service provider’s requirement, we recommended the SKF G-Ecopur as it was hands down the most optimum sealing solution for this stringent application.”
