BEARING DEVICE FOR AXLE

摘要

A bearing device adapted for use in an axle and having a bearing section using a fluorine seal for a seal section, wherein electricity is reliably conducted between an outer ring and an inner ring even if a space between the bearing section and a hub shaft is insufficient. A bearing device for an axle is provided with an inner ring (11), an outer ring (12), rolling bodies (13) interposed between the inner ring (11) and the outer rings (12), and a bearing section (10) mounted to a hub shaft (2) with seal sections (20a, 20b) respectively mounted to annular openings formed between the inner ring (11) and the outer ring (12).  The seal sections (20a, 20b) each comprise a slinger, a core, and a non-electrically-conductive seal provided between the slinger and the core.  The seal section (20b) is provided with an electrically conductive body (24) for electrically interconnecting the outer ring (12) and the inner ring (11).
