Maintenance-free bronze guide bushes
Guide bushes can be mounted radially or axially.
The sliding elements are maintenance-free and wear-resistant.
Graphite inserts provide lifelong lubrication.
Preferably for sliding speeds < 0.5 m/s. (In case of extreme loads with higher sliding speed, additional lubrication is recommended.)
