Latest Patents

One of Ishida's latest patents is a seal device for rolling bearings. This invention features a shield plate made from a circular metal plate with notches on its periphery. The design allows for parts of the peripheral portions between adjacent notches to be folded more strongly, providing a suitable prop for fitting into the outer race. This innovation prevents deformation of the outer race during the fitting of the shield plate. Another significant patent is for a sealed ball bearing. This design includes an inner race with an inner raceway track and an outer race that is concentric with the inner race. The sealed ball bearing features a plurality of balls that roll between the inner and outer raceway tracks, along with seal plates that are held by grooves on the outer race. The elastic projections of the seal plates are forced into the holding grooves, allowing for effective sealing without complicating the design.
