Latest Patents

Furukawa's latest patents include a "Bearing assembly with rotational speed detector" and a "Wheel support bearing assembly." The bearing assembly features a rotational speed detector that includes a sensor and a sensor holder made of steel. This design allows the sensor to be snap-fitted into the holder, which is treated with cationic electrocoating to improve corrosion resistance. This innovation prevents the sensor from separating from the holder after prolonged use, thereby enhancing the overall reliability of the bearing assembly.

The wheel support bearing assembly is designed to prevent foreign matter from entering the bearing assembly where a sensor is fitted. It consists of an outer member secured to a vehicle body structure, an inner member that supports a vehicle wheel, and circular rows of rolling elements positioned between the two members. A sensor cap is included to close the inboard end of the outer member, featuring an embedded insert nut and an elastic sealing member to ensure a secure fit.
