Latest Patents

Among his latest patents, Muraki has developed a "Rolling Bearing Apparatus for Swing Arm." This invention features a pair of pre-loaded ball bearings fixed to a shaft with a flange that serves as a reference surface. A clearance is secured between the flange side of the inner race of the bearing and the flange surface. Another notable patent is the "Rolling Bearing Unit," which utilizes two bearings to rotatably support a pivot in relation to a fixed shaft. This design allows for a highly precise fixation of the swing arm to the pivot, with the outer diameter of the lower bearing's outer race being larger than that of the upper bearing. The elimination of the housing used in prior art reduces the number of parts, enhancing the overall design.
