A hoist machine is provided for an elevator system that includes an elevator car and a rope, connected to the elevator car and by which the elevator car is hoisted. The output shaft of the machine motor carries a traction sheave for frictionally engaging and moving the rope, and at least two bearings support and guide the output shaft. When viewed axially, the profile of the traction sheave can be circumscribed by a profile of the bearings. The traction sheave and the output shaft can be of integral, unitary construction. The machine can also include a unitary bearing frame, having a pair of openings aligned with one another for respectively receiving and supporting one of the bearings. During assembly, the traction sheave can be inserted through one of the openings of the bearing frame.

An exemplary bearing cartridge assembly includes an inner sleeve. An outer housing is supported for rotation relative to the inner sleeve. A bearing member within the outer housing and received about the inner sleeve facilitates rotation of the outer housing relative to the inner sleeve. The bearing member has an axial dimension (e.g., a width) that is smaller than an axial inner dimension of the outer housing. The bearing member is positioned relative to the inner sleeve and the outer housing to provide a first lubricant space between one side wall of the outer housing and the bearing member and a second lubricant space between an opposite side wall of the outer housing and the bearing member. There is at least one through passage between the first and second lubricant spaces to allow lubricant to move between them.
