To provide a wheel bearing which combines a satisfactory sealing function and a large pitch circle diameter from the viewpoints of technical performance and monetary cost. A wheel bearing (10) includes a sealing device (66) including at least an outer structure (76) and an inner structure (78) that together define a baffle passage (S) having an inlet (E). The outer structure (76) defines an annular gutter (82) that opens radially outward. An inlet (E) of the baffle passage (S) and a shrink-fit portion (80) of the outer structure (76) are located on each axial side of the gutter (82). The shrink-fit portion (80) of the outer structure (76) is located on one side of a reference plane (PE) of the outer ring (20) that is perpendicular to the rotation axis (XX) and tangent to an end wall (70) of the outer ring (20) opposite the baffle passage (S) and the gutter (82).

A stormproof soffit assembly for venting an attic of a building and a method for installing the same are described herein. The stormproof soffit assembly is mountable on a wall of the building proximate an airhole in the wall opening on the attic. The stormproof soffit assembly comprises an inner vent member configured to extend along the wall of the building and forming an inner chamber having an air input port allowing air to enter the inner chamber; an exposed vent member forming an outer chamber, an upper portion of the outer chamber defining an air output port in fluid communication with the airhole in the wall; and a mesh extending between the inner chamber and the outer chamber and allowing air to flow therebetween. The air follows a chicane-shaped path when circulating through the stormproof soffit assembly between the air input port and the air output port.

This invention provides an optimization method for a magnetic compressor decompression device in an energy recovery accelerator, comprising: sequentially setting first to sixth bends along the beam direction to establish a chicane-structured magnetic compressor decompression device; determining the structure of the reverse-optimized beamline based on the decompression device; establishing constraints for a total deflection angle of 0, an anti-dispersion constraint, and a transfer matrix constraint, and solving the constraint conditions; establishing corresponding criteria with minimizing the slice center shift caused by coherent synchrotron radiation as the optimization objective; optimizing the variables of the reverse-optimized beamline based on the constraints and criteria; and reversing the placement of the reverse-optimized beamline to obtain the decompression device. This invention retains the advantages of conventional chicanes, such as a smaller deflection angle, which prevents over-compression, effectively reducing peak current intensity and helping to suppress slice center shift caused by CSR effects, thereby achieving lower emittance.
