A bearing assembly includes a bearing unit configured to support a rotatable component relative to a stationary component which may be a bearing carrier, the bearing unit including a stationary bearing ring and a rotatable bearing ring. The rotatable bearing ring is connectable to the rotatable component and the stationary bearing ring is connectable to the bearing carrier such that they are rotationally fixed. At least part of the bearing unit is not covered by the bearing carrier.

A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, and the bearing unit includes a first stationary bearing ring and a second rotatable bearing ring that is fixedly connectable to the rotating component. The bearing assembly also includes a bearing carrier to which the stationary bearing ring is attached in a rotationally fixed but axially displaceable manner, and the bearing carrier is configured to be fixedly connected to the stationary component.

A rotational coupling including a bearing assembly including a first race rotatably coupled to a second race, wherein the first race is configured to receive a plurality of first fasteners to couple the first race and the bearing assembly to a fluid supply. The rotational coupling also including a connection flange coupled to the second race and configured to receive a plurality of second fasteners to couple the connection flange to the second race. The second race includes a first side facing the connection flange and a second side opposite the first side and facing the first race, wherein the second race includes at least one access aperture configured to enable access to the plurality of first fasteners from the first side to removably couple the bearing assembly to the fluid supply.

Vacuum pump comprising a housing, a rotor shaft disposed in the housing, at least one bearing rotatably supporting the rotor shaft against the housing including an inner race in contact with the rotor shaft and an outer race in contact with the housing, and an axial spring applying an axial force onto the outer race, wherein a bearing ring is disposed between the axial spring and the outer race, the bearing ring applying a clamping force to the housing.

A bearing box for a rotating roller for supporting or transporting a high-temperature object. The bearing box includes a bearing and seal units disposed therein. A cooling jacket is disposed at an outer periphery of the bearing box so that the cooling jacket covers at least a portion of an axial region of the bearing and at least a portion of an axial region of the seal unit. The cooling jacket has a cooling water inlet and a cooling water outlet, and the bearing box is cooled by cooling water supplied to the cooling jacket through the cooling water inlet.

An exercise tool for small animals includes a rotating wheel 1 having an opening 1 formed on a front side, a wall surface portion 15 formed on a back side, and a through hole 13 formed in the wall surface portion 15; a bearing holder 2 inserted into the through hole 13 from the back side; a bearing 3 attached to this bearing holder 2; a cap member 4 coupled to the bearing holder 2 from the front side for securing the bearing holder 2 to the wall surface portion 15 of the rotating wheel 1; and a shaft member 5 attached to a stand 100. The shaft member 5 has a shaft 52 formed thereon to be press-fit and coupled to the bearing 3.

Disclosed is a sealed bearing arrangement that provides at least a bearing with an outer ring and an inner ring, which are rotatable to each other and form a rolling chamber between each other, in which a set of rolling elements. A lubricant is encompassed in the rolling chamber and the rolling chamber is sealed off from an environment by at least one sealing element. The inner ring, the outer ring and/or the sealing element includes at least one opening for providing a fluid passage through the sealing element. The bearing is arranged in a housing that is adapted to seal off the bearing from an outside environment. A lubricant is encompassed inside the housing. The housing including the at least one opening for providing a fluid passage from the inside of the housing to the outside. The opening is fluid tightly connected to an oxygen removing element and/or to a gas tank, which provides an oxygen poor to free fluid flow to the rolling chamber.
