Cast Iron Steel Flanged Bearings / JDB Bearings Energy Saving
Steel Bearings with Flange
Solid Lubricant
Applicable conditions of C303T: Normal conditions (Atmosphere)
Applicable conditions of F404: In Conditions of sea water and heavier load
Primary compositions of C303T: Graphite
Primary compositions of F404: Graphite, PTFE, paraffin
Steel Flanged JDB Bearings is backed with cast iron. The surface is regularly and finely machined with sockets in which solid lubricant is filled. Steel Flanged JDB Bearings is a typical energy saving product, which could reduce energy consumption cost while meet application requirements. Steel Flanged Bearings can be applied to auto molds and frame of the injection molders, etc.
