Abstract: A method of forming a bearing cage is generally disclosed herein. The method includes (i) forming a bearing cage from either titanium or a titanium alloy; and (ii) applying a plasma-nitriding treatment to at least one surface of the bearing cage to form a compound layer of titanium nitride including TiN and Ti2N on an outer region of the at least one surface. Step (ii) further forms a diffusion zone adjacent to the outer region, in one aspect. A surface hardness of the bearing cage that is treated by the plasma-nitriding step is at least 1000 HV. The bearing cage is configured to be used in a turbofan, turboprop, or turboshaft engine or in a helicopter gearbox, in one aspect.

Abstract: A rolling bearing, particularly for a gas turbine, includes a plurality of rolling elements (4) arranged between an inner ring (2) and outer ring (3), and a housing structure (8) on which the outer ring (3) is elastically mounted. The outer ring (3) is constructed in one piece and has a raceway section (7) forming a raceway (6) for the rolling elements (4), a spring section (21) and a flange (10) screwed to the housing structure (8). The spring section (21) is constructed from a plurality of spring bars (12) which adjoin a deflection section (9) adjoining the raceway section (7) at the end face thereof and adjoin the flange (10), are arranged radially outside the raceway section (7) and do not protrude axially beyond the deflection section (9) and the race way section (7).

Abstract: A rolling bearing for a radial bearing, in particular a cylindrical roller bearing, including a number of cage pockets (8), each intended for receiving a rolling element (6), circumferential edge strips (10, 11) which are connected to each other by webs (12, 13) to form the cage pockets (8), wherein at least one of the edge strips (10) has an end-face section of reduced wall thickness designed as an oil-collecting ring (9), a first type of oil-guiding grooves (14, 15) running parallel to the webs (12, 13) at the inner circumference of at least one edge strip (10, 11), from which grooves a respective radial bore (17) extends to the outer circumference of the edge strip (10, 11), and a second type of oil-guiding grooves (16) running at the inner circumference of at least one edge strip (10, 11), which each extend from the oil-collecting ring (9) to a cage pocket (8).
