Patent number: 6783129Abstract: A seal device (31) for a bearing system (21) is constituted by first and second seal rings (32) and (35). The first seal ring (32) is constituted by a lip seal (33) having a lip portion (33B) in sliding contact with an end face (23B) of a bush (23) which is fitted on a joint shaft (26), and a slide tube (34) having a seal surface (34C) on an end face at an axial end away from the lip portion (33B) which is formed integrally with a tubular body portion (33A) of the lip seal (33). The second seal ring (35) is fixedly fitted in a boss (22) radially on the outer side of the first seal ring (32), and provided with a seal surface (35D) on the inner side of an annular inward collar portion (35C) for sliding contact with the seal surface (34C) of the slide tube (34).Type: GrantFiled: October 23, 2002Date of Patent: August 31, 2004Assignees: Hitachi Construction Machinery Co., Ltd., Nippon Valqua Industries, Ltd.Inventors: Hideki Akita, Ryohei Suzuki, Osamu Gokita, Tatsuo Takamure, Hiromasa Muraki, Noriyuki Ando
