Advantages of TBM head seal grease
TBM head seal grease is an excluder grease for tunnel boring machines. It effectively protects the main bearing and prevents soil, water or dust ingress into the main bearing sealing. It is formulated to resist high water and ground pressures, has excellent lubrication and pumping properties as well as adhesion to all surfaces. It is highly biodegradable and based on renewable raw materials.
