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.
