Maintenance-free bronze or steel friction plates
The friction plates have a vertical sliding direction.
The bronze sliding elements are maintenance-free and wear-resistant.
Thanks to the graphite inserts, lubrication is guaranteed for life.
Steel friction plates are hardened and contain no solid lubricant.
