FLS Self Aligning Mainshaft Upgrade Kit - Eliminating risks, minimising downtime

The FLS self-aligning mainshaft is a retrofit-ready upgrade for gyratory crushers that removes the need to work beneath suspended loads during mainshaft installation. Re-engineered geometry guides and centres the shaft into position, protecting the oil contact seal from off-axis loading and reducing the rework that follows a damaged seal. Guide blocks and a controlled taper create a defined path to the final position, cutting reliance on manual adjustment and shortening time on task. Backed by FLS lifecycle service and global support, the upgrade helps standardise a safer maintenance procedure while improving crusher availability.
