A combustor for a turbine engine is provided. The combustor includes a first liner having a first hot side and a first cold side; a second liner having a second hot side and a second cold side, the second hot side and the first hot side forming a combustion chamber therebetween, the combustion chamber configured to receive an air-fuel mixture for combustion therein; and an insert including a body portion extending through the first liner, a shoulder circumscribing the body portion and abutting the first hot side, and an inlet portion coupled to the body portion and abutting the first cold side such that the inlet portion and the shoulder capture the second liner therebetween to retain the insert.

A bearing arrangement is disclosed having a bearing and a bearing support. The bearing is coupled to the bearing support at an axial side. The bearing provides first and second bearing rings that define a bearing interior there between. A first groove is formed at the first bearing ring's radial side facing the second bearing ring. A coupling element is arranged at the bearing's axial side facing the bearing support. The coupling element includes a first, preferably nose-shaped, radial protrusion that is in engagement with the first groove, and a second radial protrusion, which at least partially encompasses the bearing support at a side facing away from the bearing, so that the coupling element fastens the bearing to the bearing support. A coupling element for such a bearing arrangement is also provided.

A roller tappet includes a housing, and the housing includes a first housing element and a second housing element. The first housing element has a receiving region configured to receive a roller of the roller tappet, and the second housing element is separate from the first housing element and is forged. The first housing element may be formed from metal sheet.

An unbalanced shaft for compensating inertial forces and/or moments of inertia for a reciprocating internal combustion engine includes at least one shaft section and a bearing journal adjacent to the at least one shaft section and an unbalance mass disposed on the shaft section. The bearing journal is formed from at least two parts including a first solid bearing segment and a second solid bearing segment, and a center of gravity of the shaft section and the bearing journal is eccentric to an axis of rotation of the unbalanced shaft. The first solid bearing segment includes a portion projecting into the second solid bearing segment and the second solid bearing segment include a portion projecting into the first solid bearing segment such that the first and the second solid bearing segment are secured at least axially relative to each other.
