Abstract: An improved bearing assembly includes one unique shaft washer (158) rather than using separate forward and aft shaft washers as in the prior art; a slight lengthening of the forward roller (174) as compared to the aft roller (176); an increase in the diameter of the forward roller relative to the aft roller; an increase in the number of rollers; improved materials, particularly in the shaft washer (158) where fewer inclusions are present in the metal; and an osculation configured to provide less space and unconstrained movement between the rollers and runways. The improvements result in decreased movement or play between the shaft washers, the bearings/rollers, and the outer rings. The improvements and changes provide a compact design that fits within existing pod propulsion systems.

Abstract: A pod unit including a pod housing (1) and an assembly unit (6), a so called seating, for the pod housing (1), wherein the seating (6) has a lower portion (6A) and an upper portion (6F) as well as a base (15) for the installation of the pod housing (1) which comprises a lower casing portion (1A) for the accommodation of a propulsion unit (2, 3, 4), an intermediate portion (1B) comprising air ducts (9, 10), and an upper portion (13), which is fixedly connected to a steering engine (14, 18, 19), with a gear ring (14) to be fixed at the base (15). A cooling system having at least one fan (7) is mounted within the seating.
