Latest Patents

Kametaka's latest patents include a wheel bearing apparatus for vehicles, which features an outer member with double row outer raceway surfaces. The inner member consists of a wheel hub that is integrally formed with a wheel mounting flange. This innovative design allows for double row balls to be freely contained between the outer and inner raceway surfaces. Notably, the pitch circle diameter of the outer-side ball group is larger than that of the inner-side, enhancing the performance and durability of the bearing. The materials used in the construction of the outer member and wheel hub include medium/high carbon steel, ensuring a robust and reliable product.

Another patent focuses on a vehicle wheel bearing apparatus that incorporates a double row angular ball bearing. This design also features double rows of ball groups, with the outer-side ball group having a larger pitch circle diameter than the inner-side. The outer member is made of medium carbon steel and is hardened through high-frequency induction quenching, achieving a surface hardness of 58-64 HRC. This ensures that the bearing can withstand significant stress and wear over time.
