Latest Patents

Hashimoto's latest patents include a "Cage for Roller Bearings and Method for Manufacturing the Same." This invention features a cage that is free of fretting and abnormal noise, which can be manufactured at a low cost and easily mounted in the bearing. The cage is created by bending a metal sheet with pockets into a ring shape, temporarily joining its ends, heat-treating the formed ring to remove stress, and then separating the temporarily joined portion. This design allows the cage to rotate slower than the raceway members on the driving side of the bearing, effectively reducing fretting. Additionally, this cage is suitable for use under high-temperature conditions.
