Sealed bearing assembly

A sealed bearing arrangement comprising

• at least a bearing with an outer ring and an inner ring, that are rotatable to each other and form a rolling chamber between each other, in which a set of rolling elements is arranged, wherein the bearing is arranged in a housing, which is adapted to seal off the bearing from an outside environment, and wherein a lubricant is encompassed inside the housing, wherein
• the housing further comprises at least one opening for providing a fluid passage from the inside of the housing to the outside, wherein the opening is fluid tightly connected to an oxygen removing element and/or to a gas tank which provides an oxygen sink for a free fluid contained within the inside of the housing.

A sealed bearing arrangement comprising:

• at least a bearing with an outer ring and an inner ring that are rotatable with respect to each other and form a rolling chamber between each other, in which a set of rolling elements is arranged, wherein a lubricant is encompassed in the rolling chamber and the rolling chamber is sealed off from an environment by at least one sealing element, wherein
• the inner ring, the outer ring and/or the sealing element further comprises at least one opening for providing a fluid passage through the boundary of the sealed off rolling chamber wherein the opening is fluid tightly connected to an oxygen removing element, which provides an oxygen sink for a free fluid contained within the rolling chamber, wherein the oxygen removing element comprises a material which is adapted to absorb oxygen and releases absorbed oxygen based on a change of at least one physical parameter which impacts the oxygen removing element.

A sealed bearing arrangement comprising:

• at least a bearing with an outer ring and an inner ring that are rotatable with respect to each other and form a rolling chamber between each other, in which a set of rolling elements is arranged, wherein a lubricant is encompassed in the rolling chamber and the rolling chamber is sealed off from an environment by at least one sealing element, wherein
• the inner ring, the outer ring and/or the sealing element further comprises at least one opening for providing a fluid passage through the boundary of the sealed off rolling chamber wherein the opening is fluid tightly connected to an oxygen removing element, which provides an oxygen sink for a free fluid contained within the rolling chamber, wherein the oxygen removing element comprises a honeycomb structure.

A sealed bearing arrangement comprising:
