Description

The bronze alloy provides mechanical strength and loading capacity of the bearing and the solid lubricants provides continuous lubricating source to establish the 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.

1. Initial lubricating film, 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 alloy, provides mechanical strength and improve the impact resistance and corrosion resistance.
