1. A non-locating bearing assembly comprising:
a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a first stationary bearing ring and a second rotatable bearing ring, the rotatable bearing ring being fixedly connectable to the rotatable component,
a bearing carrier, the stationary bearing ring being axially and rotationally fixed to the bearing carrier, and
biasing means for biasing the bearing carrier away from the stationary component,
wherein the bearing carrier is configured to connect to the stationary component in a rotationally fixed but axially displaceable manner,
wherein the bearing carrier is pot-shaped and includes a cylindrical pot wall that extends axially around the stationary bearing ring,
wherein a pot base at one end of the pot wall supports an axial end of the stationary bearing ring, and a flange at another end of the pot wall is configured to cooperate with at least one connecting means for connecting the bearing carrier to the stationary component, and
wherein the biasing means comprises resilient tabs integrally formed from and bent out of the pot base or formed from and bent out of the flange.
 
8. A non-locating bearing assembly comprising:
a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a first stationary bearing ring and a second rotatable bearing ring, the rotatable bearing ring being fixedly connectable to the rotatable component,
a bearing carrier, the stationary bearing ring being axially and rotationally fixed to the bearing carrier, and
biasing means for biasing the bearing carrier away from the stationary component, the biasing means comprising a wave spring,
wherein the bearing carrier is configured to connect to the stationary component in a rotationally fixed but axially displaceable manner, and
wherein the wave spring includes a first axially resilient spring section including at least one one-layer wave-shaped spring layer that provides a spring force in the axial direction of the wave spring, and includes a further radially resilient spring section that is configured to exert a radial spring force.
 
14. A non-locating bearing assembly comprising:
a bearing unit configured to support a rotatable component relative to a stationary component, the bearing unit including a first stationary bearing ring and a second rotatable bearing ring, the rotatable bearing ring being fixedly connectable to the rotatable component,
a bearing carrier, the stationary bearing ring being axially and rotationally fixed to the bearing carrier,
biasing means for biasing the bearing carrier away from the stationary component, the biasing means comprising a plurality of spring elements disposed circumferentially around a flange of the bearing carrier, and
projections on the flange configured to extend into complementary openings in the stationary component to axially guide the bearing carrier and prevent rotation between the bearing carrier and the stationary component,
wherein the bearing carrier is configured to connect to the stationary component in a rotationally fixed but axially displaceable manner.
