The flange sleeve bushing brass material provides mechanical strength and loading capacity of the bearing and the solid lubricants provide a continuous lubricating source to establish a reliable lubricating system. It is suitable for the application conditions of middle to high load and where the frequent restarting operation is needed. The typical applications include the plastic injection machine toggle, tie bar, port machinery, dam gate, and mining machinery.
Structure:
1. Lubricating graphite, provides initial lubricating to reduce the friction.
2. Solid Lubricants, aligned according to the bearing motion direction to form lubricating film
improving the friction coefficients and wear resistance feature.
3. Bronze Material, provides mechanical strength and improve the impact resistance and corrosion resistance.
