摘要：
A bearing assembly (20) with a self-lubricated liner interface (70) supported between a spherical outside surface (72) of a sealed agricultural bearing (20b) and a steel containment housing (60,62). The interface (70) includes a lubrication-impregnated plastic interposed between the housing (60,62) and the spherical surface (72) to relieve the bearing from the high forces of shaft misalignment. The plastic liner includes a compressible portion such as radially projecting protrusions (82), O-rings (82a) or other resilient band, or compressible molded plastic (H2) to accommodate varying tolerances between the outside spherical surface (72) and housing cavity surfaces (68) and liner (70) and to bias the liner (70) against the spherical surface (72) to prevent bearing rotation. The plastic liner halves (70a,70b) fit firmly over the outside bearing surface to reduce entry of dirt and contaminants into the housing and onto the spherical bearing surface (74). The sealed bearing (20b) and self-lubricated interface (70) eliminate need for external grease ports.
