Abstract: A replaceable bearing insert may include a bearing surface including a curvature configured to be complementarily contoured to a trunnion ball. The bearing surface may be configured to be in confronting engagement with the trunnion ball. An outer surface opposite the bearing surface may be configured to be received in confronting engagement with an inner surface of an adapter. A first semi-annular flange may extend radially outwardly beyond the outer surface. A second semi-annular flange may extend radially outwardly beyond the outer surface. The first semi-annular flange and the second semi-annular flange may be configured to extend along a first side and a second side of the adapter, respectively, such that the inner surface of the adapter is positioned between the first semi-annular flange and the second semi-annular flange.

Abstract: A pin connection for a machine is provided that comprises a structural member that defines a pin receiving bore, a bearing housing that defines a bearing receiving bore, a self-lubricating bearing that defines a pin receiving bore, and a pin that is disposed in the bores of the bearing and the structural member. The pin connection may further comprise a seal assembly that is disposed in the bearing receiving bore of the bearing housing, the seal assembly comprising a micro-cellular closed cell foam member and a first rigid member.
