Patent number: 9797453Abstract: A wheel bearing apparatus has an outer member, an inner member, at least one inner ring fit onto the inner member. Double row rolling elements are rollably arranged between the outer and inner raceway surfaces, via cages. A seal is mounted on one end of the outer member. The seal has side lips adapted to be in sliding contact with the wheel hub. The seal has three inclined side lips each extending radially outward from the seal body. The lips are adapted to be in sliding contact with the base of the wheel mounting flange. Interference of the side lips against the base of the wheel mounting flange is set so that the radially inner side lip has a smaller interference than that of the radially outer side lips, in order.Type: GrantFiled: October 3, 2006Date of Patent: October 24, 2017Assignee: NTN CorporationInventors: Takayuki Norimatsu, Hiroaki Itakura, Hironori Imanaka, Syougo Suzuki, Isao Hirai, Hiroya Kato, Akira Fujimura, Kikuo Fukada

Patent number: 7878411Abstract: To provide a wheel support bearing device, in which the status of actual use is detected and stored as a history, an IC tag (9) capable of a contactless communication is affixed to the wheel support bearing device. This IC tag (9) is rendered to be a sensor incorporated IC tag integrated with or electrically connected with a sensor for detecting an object to be detected of the wheel support bearing device and a detection of the sensor is inputted through an input channel separate from a channel for the contactless communication. The sensor referred to above may be, for example, a coil and a magnet (10) capable of passing in the vicinity of the sensor incorporated IC tag (9) by the effect of a relative rotation.Type: GrantFiled: July 25, 2005Date of Patent: February 1, 2011Assignee: NTN CorporationInventors: Masahiro Muranaka, Hiroaki Itakura, Shinji Morita, Yoshiaki Kuchiki
