A device for lubricating and cooling a turbomachine rolling bearing is at least partially annular. The device comprises a first duct and a second duct inclined with respect to the first duct. The first duct is configured to be in thermal contact with an outer ring of the rolling bearing that at least partially surrounds same. The second duct is fluidically connected to the first duct. The first duct is configured to circulate the lubricant for cooling the outer ring, towards a discharge outlet of the lubricant. The second duct is configured to eject the lubricant through a lubrication outlet towards the rolling bearing.

The sealing system seals the bearings of a floor machine. The sealing system provides a sealing base and a sealing head. A seal is positioned between the sealing base and the sealing head to seal the bearing. The sealing base secures to the driver plate. The sealing base extends upward above the bearing. The sealing head is positioned above the sealing base. The sealing head is positioned radially inward of the sealing base at the bearing. The sealing head extends upward above the sealing base and extends outward beyond an upper portion of the sealing base to be located radially outward from the sealing base. The seal is located at an upper portion of the sealing base. The seal is located radially outward from the sealing base. The seal is located below the sealing head at a sealing aperture located between a sealing shoulder and a sealing neck.

The steering function-equipped hub unit includes: a turning shaft-equipped hub bearing (15) including an inner ring, an outer ring, and rolling elements in double rows interposed between the inner ring and the outer ring, the turning shaft-equipped hub bearing having a turning shaft extending in a vertical direction; a unit support member (3) rotatably supporting the turning shaft-equipped hub bearing (15) about a turning axis of the turning shaft; and a steering actuator (5) configured to rotationally drive the turning shaft-equipped hub bearing (15) about the turning axis (A). The unit support member (3) and the steering actuator (5) include a flange (3a) and an end portion (25Aa), respectively, to be removably fixed to a knuckle (6) which is a chassis frame component of a vehicle.

A power steering device includes a bearing rotatably supporting the tip side of a worm shaft, a gear case provided with the housing hole for housing the worm shaft and a holder housing the bearing. The holder includes a first holder holding the bearing, a second holder having the guide part configured to guide a movement of the second bearing toward a worm wheel, and a spring provided in a compressed state between the first holder and the second holder and configured to bias the first holder toward the worm wheel. The second holder includes a holder opening part configured to allow the bearing and the first holder to pass through thereof in the guiding direction of the guide part to guide the bearing, and the first holder faces an inner peripheral surface of the housing hole through the holder opening part.

An object of the present invention is to provide a steering apparatus capable of improving a function of a bearing that supports a steering shaft. A steering apparatus includes a steering shaft, a first housing member, a second housing member, and a bearing. The steering shaft rotates according to a rotation of a steering wheel. The first housing member is located on one side in a rotational axial direction of the steering shaft, and includes a cylindrical portion and a flange portion. The cylindrical portion surrounds the steering shaft. The flange portion extends in a radial direction with respect to a rotational axis of the steering shaft to an outer side of the cylindrical portion in the radial direction. The second housing member is provided on the other side in the rotational axial direction, and forms a housing together with the first housing member. The second housing member includes a connection portion and a containing portion. The connection portion is connected to the flange portion of the first housing member. The containing portion contains a part of the steering shaft. The bearing is provided at a position that overlaps the flange portion in the rotational axial direction on an inner peripheral side of the cylindrical portion of the first housing member, and supports the steering shaft.
